• Speed up lighting in deferred shading

  - by kochol

  I implemented a simple deferred shading renderer. I use 3 G-Buffer for storing position (R32F), normal (G16R16F) and albedo (ARGB8). I use sphere map algorithm to store normals in world space. Currently I use inverse of view * projection matrix to calculate the position of each pixel from stored depth value. First I want to avoid per pixel matrix multiplication for calculating the position. Is there another way to store and calculate position in G-Buffer without the need of matrix multiplication Store the normal in view space Every lighting in my engine is in world space and I want do the lighting in view space to speed up my lighting pass. I want an optimized lighting pass for my deferred engine.

• Deferred Rendering With Diffuse,Specular, and Normal maps

  - by John

  I have been reading up on deferred rendering and I am trying to implement a renderer using the Sponza atrium model, which can be found here, as my sandbox.Note I am also using OpenGL 3.3 and GLSL. I am loading the model from a Wavefront OBJ file using Assimp. I extract all geometry information including tangents and bitangents. For all the aiMaterials,I extract the following information which essentially comes from the sponza.mtl file. Ambient/Diffuse/Specular/Emissive Reflectivity Coefficients(Ka,Kd,Ks,Ke) Shininess Diffuse Map Specular Map Normal Map I understand that I must render vertex attributes such as position ,normals,texture coordinates to textures as well as depth for the second render pass. A lot of resources mention putting colour information into a g-buffer in the initial render pass but do you not require the diffuse,specular and normal maps and therefore lights to determine the fragment colour? I know that doesnt make since sense because lighting should be done in the second render pass. In terms of normal mapping, do you essentially just pass the tangent,bitangents, and normals into g-buffers and then construct the tangent matrix and apply it to the sampled normal from the normal map. Ultimately, I would like to know how to incorporate this material information into my deferred renderer.

• Deferred contexts and inheriting state from the immediate context

  - by dreijer

  I took my first stab at using deferred contexts in DirectX 11 today. Basically, I created my deferred context using CreateDeferredContext() and then drew a simple triangle strip with it. Early on in my test application, I call OMSetRenderTargets() on the immediate context in order to render to the swap chain's back buffer. Now, after having read the documentation on MSDN about deferred contexts, I assumed that calling ExecuteCommandList() on the immediate context would execute all of the deferred commands as "an extension" to the commands that had already been executed on the immediate context, i.e. the triangle strip I rendered in the deferred context would be rendered to the swap chain's back buffer. That didn't seem to be the case, however. Instead, I had to manually pull out the immediate context's render target (using OMGetRenderTargets()) and then set it on the deferred context with OMSetRenderTargets(). Am I doing something wrong or is that the way deferred contexts work?

• LIMBO fails on startup with Internal errors - invalid parameters received

  - by user61262

  I installed LIMBO from the Humble Bundle V and as far as I am aware, this has wine packaged with it (I also installed the latest from the repo's in case is was because of that). However the game doesn't even start and fails with the message: Wine Program Error Internal errors - invalid parameters received. Is there a way to log the error or does anyone know why this happens? This question was asked previously but it seems to have disappeared. My Graphics cards is a Geforece GT 250 Cheers ice. [edit: Wine outputs the following error: wine /opt/limbo/support/limbo/drive_c/Program\ Files/limbo/limbo.exe fixme:system:SystemParametersInfoW Unimplemented action: 59 (SPI_SETSTICKYKEYS) fixme:system:SystemParametersInfoW Unimplemented action: 53 (SPI_SETTOGGLEKEYS) fixme:system:SystemParametersInfoW Unimplemented action: 51 (SPI_SETFILTERKEYS) fixme:win:EnumDisplayDevicesW ((null),0,0x32f580,0x00000000), stub! err:x11settings:X11DRV_ChangeDisplaySettingsEx No matching mode found 1920x1080x32 @60!

• JQuery Deferred - Adding to the Deferred contract

  - by MgSam

  I'm trying to add another asynchronous call to the contract of an existing Deferred before its state is set to success. Rather than try and explain this in English, see the following pseudo-code: $.when( $.ajax({ url: someUrl, data: data, async: true, success: function (data, textStatus, jqXhr) { console.log('Call 1 done.') jqXhr.pipe( $.ajax({ url: someUrl, data: data, async: true, success: function (data, textStatus, jqXhr) { console.log('Call 2 done.'); }, }) ); }, }), $.ajax({ url: someUrl, data: data, async: true, success: function (data, textStatus, jqXhr) { console.log('Call 3 done.'); }, }) ).then(function(){ console.log('All done!'); }); Basically, Call 2 is dependent on the results of Call 1. I want Call 1 and Call 3 to be executed in parallel. Once all 3 calls are complete, I want the All Done code to execute. My understanding is that Deferred.pipe() is supposed to chain another asynchronous call to the given deferred, but in practice, I always get Call 2 completing after All Done. Does anyone know how to get jQuery's Deferred to do what I want? Hopefully the solution doesn't involve ripping the code apart into chunks any further. Thanks for any help.

• XNA 4 Deferred Rendering deforms the model

  - by Tomáš Bezouška

  I have a problem when rendering a model of my World - when rendered using BasicEffect, it looks just peachy. Problem is when I render it using deferred rendering. See for yourselves: what it looks like: http://imageshack.us/photo/my-images/690/survival.png/ what it should look like: http://imageshack.us/photo/my-images/521/survival2.png/ (Please ignora the cars, they shouldn't be there. Nothing changes when they are removed) Im using Deferred renderer from www.catalinzima.com/tutorials/deferred-rendering-in-xna/introduction-2/ except very simplified, without the custom content processor. Here's the code for the GBuffer shader: float4x4 World; float4x4 View; float4x4 Projection; float specularIntensity = 0.001f; float specularPower = 3; texture Texture; sampler diffuseSampler = sampler_state { Texture = (Texture); MAGFILTER = LINEAR; MINFILTER = LINEAR; MIPFILTER = LINEAR; AddressU = Wrap; AddressV = Wrap; }; struct VertexShaderInput { float4 Position : POSITION0; float3 Normal : NORMAL0; float2 TexCoord : TEXCOORD0; }; struct VertexShaderOutput { float4 Position : POSITION0; float2 TexCoord : TEXCOORD0; float3 Normal : TEXCOORD1; float2 Depth : TEXCOORD2; }; VertexShaderOutput VertexShaderFunction(VertexShaderInput input) { VertexShaderOutput output; float4 worldPosition = mul(input.Position, World); float4 viewPosition = mul(worldPosition, View); output.Position = mul(viewPosition, Projection); output.TexCoord = input.TexCoord; //pass the texture coordinates further output.Normal = mul(input.Normal,World); //get normal into world space output.Depth.x = output.Position.z; output.Depth.y = output.Position.w; return output; } struct PixelShaderOutput { half4 Color : COLOR0; half4 Normal : COLOR1; half4 Depth : COLOR2; }; PixelShaderOutput PixelShaderFunction(VertexShaderOutput input) { PixelShaderOutput output; output.Color = tex2D(diffuseSampler, input.TexCoord); //output Color output.Color.a = specularIntensity; //output SpecularIntensity output.Normal.rgb = 0.5f * (normalize(input.Normal) + 1.0f); //transform normal domain output.Normal.a = specularPower; //output SpecularPower output.Depth = input.Depth.x / input.Depth.y; //output Depth return output; } technique Technique1 { pass Pass1 { VertexShader = compile vs_2_0 VertexShaderFunction(); PixelShader = compile ps_2_0 PixelShaderFunction(); } } And here are the rendering parts in XNA: public void RednerModel(Model model, Matrix world) { Matrix[] boneTransforms = new Matrix[model.Bones.Count]; model.CopyAbsoluteBoneTransformsTo(boneTransforms); Game.GraphicsDevice.DepthStencilState = DepthStencilState.Default; Game.GraphicsDevice.BlendState = BlendState.Opaque; Game.GraphicsDevice.RasterizerState = RasterizerState.CullCounterClockwise; foreach (ModelMesh mesh in model.Meshes) { foreach (ModelMeshPart meshPart in mesh.MeshParts) { GBufferEffect.Parameters["View"].SetValue(Camera.Instance.ViewMatrix); GBufferEffect.Parameters["Projection"].SetValue(Camera.Instance.ProjectionMatrix); GBufferEffect.Parameters["World"].SetValue(boneTransforms[mesh.ParentBone.Index] * world); GBufferEffect.Parameters["Texture"].SetValue(meshPart.Effect.Parameters["Texture"].GetValueTexture2D()); GBufferEffect.Techniques[0].Passes[0].Apply(); RenderMeshpart(mesh, meshPart); } } } private void RenderMeshpart(ModelMesh mesh, ModelMeshPart part) { Game.GraphicsDevice.SetVertexBuffer(part.VertexBuffer); Game.GraphicsDevice.Indices = part.IndexBuffer; Game.GraphicsDevice.DrawIndexedPrimitives(PrimitiveType.TriangleList, 0, 0, part.NumVertices, part.StartIndex, part.PrimitiveCount); } I import the model using the built in content processor for FBX. The FBX is created in 3DS Max. I don't know the exact details of that export, but if you think it might be relevant, I will get them from my collegue who does them. What confuses me though is why the BasicEffect approach works... seems the FBX shouldnt be a problem. Any thoughts? They will be greatly appreciated :)

• DX9 Deferred Rendering, GBuffer displays as clear color only

  - by Fire31

  I'm trying to implement Catalin Zima's Deferred Renderer in a very lightweight c++ DirectX 9 app (only renders a skydome and a model), at this moment I'm trying to render the gbuffer, but I'm having a problem, the screen shows only the clear color, no matter how much I move the camera around. However, removing all the render target operations lets the app render the scene normally, even if the models are being applied the renderGBuffer effect. Any ideas of what I'm doing wrong?

• XNA Deferred Shading, Replace BasicEffect

  - by Alex

  I have implemented deferred shading in my XNA 4.0 project, meaning that I need all objects to start out with the same shader "RenderGBuffer.fx". How can I use a custom Content Processor to: Not load any textures by default (I want to manually do this) Use "RenderGBuffer.fx" as the default shader instead of BasicEffect Below is the progress so far public class DeferredModelProcessor : ModelProcessor { EffectMaterialContent deferredShader; public DeferredModelProcessor() { } protected override MaterialContent ConvertMaterial(MaterialContent material, ContentProcessorContext context) { deferredShader = new EffectMaterialContent(); deferredShader.Effect = new ExternalReference<EffectContent>("DeferredShading/RenderGBuffer.fx"); return context.Convert<MaterialContent, MaterialContent>(deferredShader, typeof(MaterialProcessor).Name); } }

• Ray Tracing Shadows in deferred rendering

  - by Grieverheart

  Recently I have programmed a raytracer for fun and found it beutifully simple how shadows are created compared to a rasterizer. Now, I couldn't help but I think if it would be possible to implement somthing similar for ray tracing of shadows in a deferred renderer. The way I though this could work is after drawing to the gbuffer, in a separate pass and for each pixel to calculate rays to the lights and draw them as lines of unique color together with the geometry (with color 0). The lines will be cut-off if there is occlusion and this fact could be used in a fragment shader to calculate which rays are occluded. I guess there must be something I'm missing, for example I'm not sure how the fragment shader could save the occlusion results for each ray so that they are available for pixel at the ray's origin. Has this method been tried before, is it possible to implement it as I described and if yes what would be the drawbacks in performance of calculating shadows this way?

• Projective texture and deferred lighting

  - by Vodácek

  In my previous question, I asked whether it is possible to do projective texturing with deferred lighting. Now (more than half a year later) I have a problem with my implementation of the same thing. I am trying to apply this technique in light pass. (my projector doesn't affect albedo). I have this projector View a Projection matrix: Matrix projection = Matrix.CreateOrthographicOffCenter(-halfWidth * Scale, halfWidth * Scale, -halfHeight * Scale, halfHeight * Scale, 1, 100000); Matrix view = Matrix.CreateLookAt(Position, Target, Vector3.Up); Where halfWidth and halfHeight is are half of the texture's width and height, Position is the Projector's position and target is the projector's target. This seems to be ok. I am drawing full screen quad with this shader: float4x4 InvViewProjection; texture2D DepthTexture; texture2D NormalTexture; texture2D ProjectorTexture; float4x4 ProjectorViewProjection; sampler2D depthSampler = sampler_state { texture = <DepthTexture>; minfilter = point; magfilter = point; mipfilter = point; }; sampler2D normalSampler = sampler_state { texture = <NormalTexture>; minfilter = point; magfilter = point; mipfilter = point; }; sampler2D projectorSampler = sampler_state { texture = <ProjectorTexture>; AddressU = Clamp; AddressV = Clamp; }; float viewportWidth; float viewportHeight; // Calculate the 2D screen position of a 3D position float2 postProjToScreen(float4 position) { float2 screenPos = position.xy / position.w; return 0.5f * (float2(screenPos.x, -screenPos.y) + 1); } // Calculate the size of one half of a pixel, to convert // between texels and pixels float2 halfPixel() { return 0.5f / float2(viewportWidth, viewportHeight); } struct VertexShaderInput { float4 Position : POSITION0; }; struct VertexShaderOutput { float4 Position :POSITION0; float4 PositionCopy : TEXCOORD1; }; VertexShaderOutput VertexShaderFunction(VertexShaderInput input) { VertexShaderOutput output; output.Position = input.Position; output.PositionCopy=output.Position; return output; } float4 PixelShaderFunction(VertexShaderOutput input) : COLOR0 { float2 texCoord =postProjToScreen(input.PositionCopy) + halfPixel(); // Extract the depth for this pixel from the depth map float4 depth = tex2D(depthSampler, texCoord); //return float4(depth.r,0,0,1); // Recreate the position with the UV coordinates and depth value float4 position; position.x = texCoord.x * 2 - 1; position.y = (1 - texCoord.y) * 2 - 1; position.z = depth.r; position.w = 1.0f; // Transform position from screen space to world space position = mul(position, InvViewProjection); position.xyz /= position.w; //compute projection float3 projection=tex2D(projectorSampler,postProjToScreen(mul(position,ProjectorViewProjection)) + halfPixel()); return float4(projection,1); } In first part of pixel shader is recovered position from G-buffer (this code I am using in other shaders without any problem) and then is tranformed to projector viewprojection space. Problem is that projection doesn't appear. Here is an image of my situation: The green lines are the rendered projector frustum. Where is my mistake hidden? I am using XNA 4. Thanks for advice and sorry for my English. EDIT: Shader above is working but projection was too small. When I changed the Scale property to a large value (e.g. 100), the projection appears. But when the camera moves toward the projection, the projection expands, as can bee seen on this YouTube video.

• Deferred rendering with VSM - Scaling light depth loses moments

  - by user1423893

  I'm calculating my shadow term using a VSM method. This works correctly when using forward rendered lights but fails with deferred lights. // Shadow term (1 = no shadow) float shadow = 1; // [Light Space -> Shadow Map Space] // Transform the surface into light space and project // NB: Could be done in the vertex shader, but doing it here keeps the // "light shader" abstraction and doesn't limit the number of shadowed lights float4x4 LightViewProjection = mul(LightView, LightProjection); float4 surf_tex = mul(position, LightViewProjection); // Re-homogenize // 'w' component is not used in later calculations so no need to homogenize (it will equal '1' if homogenized) surf_tex.xyz /= surf_tex.w; // Rescale viewport to be [0,1] (texture coordinate system) float2 shadow_tex; shadow_tex.x = surf_tex.x * 0.5f + 0.5f; shadow_tex.y = -surf_tex.y * 0.5f + 0.5f; // Half texel offset //shadow_tex += (0.5 / 512); // Scaled distance to light (instead of 'surf_tex.z') float rescaled_dist_to_light = dist_to_light / LightAttenuation.y; //float rescaled_dist_to_light = surf_tex.z; // [Variance Shadow Map Depth Calculation] // No filtering float2 moments = tex2D(ShadowSampler, shadow_tex).xy; // Flip the moments values to bring them back to their original values moments.x = 1.0 - moments.x; moments.y = 1.0 - moments.y; // Compute variance float E_x2 = moments.y; float Ex_2 = moments.x * moments.x; float variance = E_x2 - Ex_2; variance = max(variance, Bias.y); // Surface is fully lit if the current pixel is before the light occluder (lit_factor == 1) // One-tailed inequality valid if float lit_factor = (rescaled_dist_to_light <= moments.x - Bias.x); // Compute probabilistic upper bound (mean distance) float m_d = moments.x - rescaled_dist_to_light; // Chebychev's inequality float p = variance / (variance + m_d * m_d); p = ReduceLightBleeding(p, Bias.z); // Adjust the light color based on the shadow attenuation shadow *= max(lit_factor, p); This is what I know for certain so far: The lighting is correct if I do not try and calculate the shadow term. (No shadows) The shadow term is correct when calculated using forward rendered lighting. (VSM works with forward rendered lights) With the current rescaled light distance (lightAttenuation.y is the far plane value): float rescaled_dist_to_light = dist_to_light / LightAttenuation.y; The light is correct and the shadow appears to be zoomed in and misses the blurring: When I do not rescale the light and use the homogenized 'surf_tex': float rescaled_dist_to_light = surf_tex.z; the shadows are blurred correctly but the lighting is incorrect and the cube model is no longer lit Why is scaling by the far plane value (LightAttenuation.y) zooming in too far? The only other factor involved is my world pixel position, which is calculated as follows: // [Position] float4 position; // [Screen Position] position.xy = input.PositionClone.xy; // Use 'x' and 'y' components already homogenized for uv coordinates above position.z = tex2D(DepthSampler, texCoord).r; // No need to homogenize 'z' component position.z = 1.0 - position.z; position.w = 1.0; // 1.0 = position.w / position.w // [World Position] position = mul(position, CameraViewProjectionInverse); // Re-homogenize position (xyz AND w, otherwise shadows will bend when camera is close) position.xyz /= position.w; position.w = 1.0; Using the inverse matrix of the camera's view x projection matrix does work for lighting but maybe it is incorrect for shadow calculation? EDIT: Light calculations for shadow including 'dist_to_light' // Work out the light position and direction in world space float3 light_position = float3(LightViewInverse._41, LightViewInverse._42, LightViewInverse._43); // Direction might need to be negated float3 light_direction = float3(-LightViewInverse._31, -LightViewInverse._32, -LightViewInverse._33); // Unnormalized light vector float3 dir_to_light = light_position - position; // Direction from vertex float dist_to_light = length(dir_to_light); // Normalise 'toLight' vector for lighting calculations dir_to_light = normalize(dir_to_light); EDIT2: These are the calculations for the moments (depth) //============================================= //---[Vertex Shaders]-------------------------- //============================================= DepthVSOutput depth_VS( float4 Position : POSITION, uniform float4x4 shadow_view, uniform float4x4 shadow_view_projection) { DepthVSOutput output = (DepthVSOutput)0; // First transform position into world space float4 position_world = mul(Position, World); output.position_screen = mul(position_world, shadow_view_projection); output.light_vec = mul(position_world, shadow_view).xyz; return output; } //============================================= //---[Pixel Shaders]--------------------------- //============================================= DepthPSOutput depth_PS(DepthVSOutput input) { DepthPSOutput output = (DepthPSOutput)0; // Work out the depth of this fragment from the light, normalized to [0, 1] float2 depth; depth.x = length(input.light_vec) / FarPlane; depth.y = depth.x * depth.x; // Flip depth values to avoid floating point inaccuracies depth.x = 1.0f - depth.x; depth.y = 1.0f - depth.y; output.depth = depth.xyxy; return output; } EDIT 3: I have tried the folloiwng: float4 pp; pp.xy = input.PositionClone.xy; // Use 'x' and 'y' components already homogenized for uv coordinates above pp.z = tex2D(DepthSampler, texCoord).r; // No need to homogenize 'z' component pp.z = 1.0 - pp.z; pp.w = 1.0; // 1.0 = position.w / position.w // Determine the depth of the pixel with respect to the light float4x4 LightViewProjection = mul(LightView, LightProjection); float4x4 matViewToLightViewProj = mul(CameraViewProjectionInverse, LightViewProjection); float4 vPositionLightCS = mul(pp, matViewToLightViewProj); float fLightDepth = vPositionLightCS.z / vPositionLightCS.w; // Transform from light space to shadow map texture space. float2 vShadowTexCoord = 0.5 * vPositionLightCS.xy / vPositionLightCS.w + float2(0.5f, 0.5f); vShadowTexCoord.y = 1.0f - vShadowTexCoord.y; // Offset the coordinate by half a texel so we sample it correctly vShadowTexCoord += (0.5f / 512); //g_vShadowMapSize This suffers the same problem as the second picture. I have tried storing the depth based on the view x projection matrix: output.position_screen = mul(position_world, shadow_view_projection); //output.light_vec = mul(position_world, shadow_view); output.light_vec = output.position_screen; depth.x = input.light_vec.z / input.light_vec.w; This gives a shadow that has lots surface acne due to horrible floating point precision errors. Everything is lit correctly though. EDIT 4: Found an OpenGL based tutorial here I have followed it to the letter and it would seem that the uv coordinates for looking up the shadow map are incorrect. The source uses a scaled matrix to get the uv coordinates for the shadow map sampler /// <summary> /// The scale matrix is used to push the projected vertex into the 0.0 - 1.0 region. /// Similar in role to a * 0.5 + 0.5, where -1.0 < a < 1.0. /// <summary> const float4x4 ScaleMatrix = float4x4 ( 0.5, 0.0, 0.0, 0.0, 0.0, -0.5, 0.0, 0.0, 0.0, 0.0, 0.5, 0.0, 0.5, 0.5, 0.5, 1.0 ); I had to negate the 0.5 for the y scaling (M22) in order for it to work but the shadowing is still not correct. Is this really the correct way to scale? float2 shadow_tex; shadow_tex.x = surf_tex.x * 0.5f + 0.5f; shadow_tex.y = surf_tex.y * -0.5f + 0.5f; The depth calculations are exactly the same as the source code yet they still do not work, which makes me believe something about the uv calculation above is incorrect.

• Deferred rendering order?

  - by Nick Wiggill

  There are some effects for which I must do multi-pass rendering. I've got the basics set up (FBO rendering etc.), but I'm trying to get my head around the most suitable setup. Here's what I'm thinking... The framebuffer objects: FBO 1 has a color attachment and a depth attachment. FBO 2 has a color attachment. The render passes: Render g-buffer: normals and depth (used by outline & DoF blur shaders); output to FBO no. 1. Render solid geometry, bold outlines (as in toon shader), and fog; output to FBO no. 2. (can all render via a single fragment shader -- I think.) (optional) DoF blur the scene; output to the default frame buffer OR ELSE render FBO2 directly to default frame buffer. (optional) Mesh wireframes; composite over what's already in the default framebuffer. Does this order seem viable? Any obvious mistakes?

• twisted deferred/callbacks and asynchronous execution

  - by NetSkay

  hey guys, quick question about twisted and python... im trying to figure out how can i make my code more asynchronous using twisted and ive come to sort of a dead end, if a function of mine returns a deferred object, then i add a list of callbacks, the first callback will be called after the deferred function provides some result through deferred_obj.callback, then, in the chain of callbacks, the first callback will do something with the data and call the second callback and etc. however chained callbacks will not be considered asynchronous because they're chained and the event loop will keep firing each one of them concurrently until there is no more, right? however, if i have a deferred object, and i attach as its callback the deferred_obj.callback as in d.addCallback(deferred_obj.callback) then this will be considered asynchronous, because the deferred_obj is waiting for the data, and then the method that will pass the data is waiting on data as well, however once i d.callback 'd' object processes the data then it call deferred_obj.callback however since this object is deferred, unlike the case of chained callbacks, it will execute asynchronously... correct? meaning chained callbacks are NOT asynchronous while chained deferreds are, correct? thank you PS: assuming all of my code is non-blocking

• Deferred vs Immediate execution in Linq

  - by Jalpesh P. Vadgama

  In this post, We are going to learn about Deferred vs Immediate execution in Linq.  There an interesting variations how Linq operators executes and in this post we are going to learn both Deferred execution and immediate execution. What is Deferred Execution? In the Deferred execution query will be executed and evaluated at the time of query variables usage. Let’s take an example to understand Deferred Execution better. Example: Following is a code for that. using System; using System.Collections.Generic; using System.Linq; namespace ConsoleApplication1 { class Program { static void Main(string[] args) { var customers = new List<Customer>( new[] { new Customer{FirstName = "Jalpesh",LastName = "Vadgama"}, new Customer{FirstName = "Vishal",LastName = "Vadgama"}, new Customer{FirstName = "Tushar",LastName = "Maru"} } ); var newCustomers = customers.Where(c => c.LastName == "Vadgama"); customers.Add(new Customer {FirstName = "Teerth", LastName = "Vadgama"}); foreach (var c in newCustomers) { Console.WriteLine(c.FirstName); } } public class Customer { public string FirstName { get; set; } public string LastName { get; set; } } } } More on my personal blog @www.dotnetjalps.com

• Google Web Toolkit Deferred Binding Issue

  - by snctln

  I developed a web app using GWT about 2 years ago, since then the application has evolved. In its current state it relies on fetching a single XML file and parsing the information from it. Overall this works great. A requirement of this app is that it needs to be able to be ran from the filesystem (file:///..) as well as the traditional model of running from a webserver (http://...) Fetching this file from a webserver works exactly as expected using a RequestBuilder object. When running the app from the filesystem Firefox, Opera, Safari, and Chrome all behave as expected. When running the app from the filesystem using IE7 or IE8 the RequestBuilder.send() call fails, the information about the error suggests that there is a problem accessing the file due to violating the same origin policy. The app worked as expected in IE6 but not in IE7 or IE8. So I looked at the source code of RequestBuilder.java and saw that the actual request was being executed with an XMLHttpRequest GWT object. So I looked at the source code for XMLHttpRequest.java and found out some information. Here is the code (starts at line 83 in XMLHttpRequest.java) public static native XMLHttpRequest create() /*-{ if ($wnd.XMLHttpRequest) { return new XMLHttpRequest(); } else { try { return new ActiveXObject('MSXML2.XMLHTTP.3.0'); } catch (e) { return new ActiveXObject("Microsoft.XMLHTTP"); } } }-*/; So basically if an XMLHttpRequest cannot be created (like in IE6 because it is not available) an ActiveXObject is used instead. I read up a little bit more on the IE implementation of XMLHttpRequest, and it appears that it is only supported for interacting with files on a webserver. I found a setting in IE8 (Tools-Internet Options-Advanced-Security-Enable native XMLHTTP support), when I uncheck this box my app works. I assume this is because I am more of less telling IE to not use their implementation of XmlHttpRequest, so GWT just uses an ActiveXObject because it doesn't think the native XmlHttpRequest is available. This fixes the problem, but is hardly a long term solution. I can currently catch a failed send request and verify that it was trying to fetch the XML file from the filesystem using normal GWT. What I would like to do in this case is catch the IE7 and IE8 case and have them use a ActiveXObject instead of a native XmlHttpRequest object. There was a posting on the GWT google group that had a supposed solution for this problem (link). Looking at it I can tell that it was created for an older version of GWT. I am using the latest release and think that this is more or less what I would like to do (use GWT deferred binding to detect a specific browser type and run my own implementation of XMLHttpRequest.java in place of the built in GWT implementation). Here is the code that I am trying to use package com.mycompany.myapp.client; import com.google.gwt.xhr.client.XMLHttpRequest; public class XMLHttpRequestIE7or8 extends XMLHttpRequest { // commented out the "override" so that eclipse and the ant build script don't throw errors //@Override public static native XMLHttpRequest create() /*-{ try { return new ActiveXObject('MSXML2.XMLHTTP.3.0'); } catch (e) { return new ActiveXObject("Microsoft.XMLHTTP"); } }-*/; // have an empty protected constructor so the ant build script doesn't throw errors // the actual XMLHttpRequest constructor is empty as well so this shouldn't cause any problems protected XMLHttpRequestIE7or8() { } }; And here are the lines that I added to my module xml <replace-with class="com.mycompany.myapp.client.XMLHttpRequestIE7or8"> <when-type-is class="com.google.gwt.xhr.client.XMLHttpRequest"/> <any> <when-property-is name="user.agent" value="ie7" /> <when-property-is name="user.agent" value="ie8" /> </any> </replace-with> From what I can tell this should work, but my code never runs. Does anyone have any idea of what I am doing wrong? Should I not do this via deferred binding and just use native javascript when I catch the fail case instead? Is there a different way of approaching this problem that I have not mentioned? All replies are welcome.

• Use depth bias for shadows in deferred shading

  - by cubrman

  We are building a deferred shading engine and we have a problem with shadows. To add shadows we use two maps: the first one stores the depth of the scene captured by the player's camera and the second one stores the depth of the scene captured by the light's camera. We then ran a shader that analyzes the two maps and outputs the third one with the ready shadow areas for the current frame. The problem we face is a classic one: Self-Shadowing: A standard way to solve this is to use the slope-scale depth bias and depth offsets, however as we are doing things in a deferred way we cannot employ this algorithm. Any attempts to set depth bias when capturing light's view depth produced no or unsatisfying results. So here is my question: MSDN article has a convoluted explanation of the slope-scale: bias = (m × SlopeScaleDepthBias) + DepthBias Where m is the maximum depth slope of the triangle being rendered, defined as: m = max( abs(delta z / delta x), abs(delta z / delta y) ) Could you explain how I can implement this algorithm manually in a shader? Maybe there are better ways to fix this problem for deferred shadows?

• Deferred Open Source licensing

  - by Thomas W.

  Are there established models for releasing an initially proprietary piece of software under FLOSS conditions after a defined period or a certain point of time? The main problem here is that all parties involved must be able to trust that the Open Source licensing will actually take place at the defined time and no party can further defer or cancel this process. Clearly such a model has its problems, for example it's problematic to deal with contributions from "outside", legally and technically. Ghostscript is a prominent example where a deferred model has been used and abandoned. However, if certain parties involved will insist on keeping the software proprietary, at least for a certain period of time, then the only options are a deferred Open Source licensing model or no Open Source licensing at all. I think I read about services that serve as trusted parties who take care of Open Sourcing the software. However, I was not successful in spotting any of those.

• What are deferred callbacks?

  - by tentimes

  I understand the idea of a callback, where I pass a function into another function and that function then uses the supplied function at will. I am struggling to understand deferred callbacks, even after googling it. Could someone provide a simple explanation please? I program in Ruby, but also know C/C++ a bit, but most of all I was a experienced assembly language programmer. So I am wondering is it a bit like a stack of callback addresses that get pop'd? I am hoping to learn jquery or node.js and these deferred callbacks seem integral to both. I understand basic threading principles (though mutex object makes my head hurt ;)
