  • Data Structures: What are some common examples of problems where "buffers" come into action?

    - by Dark Templar
    I was just wondering if there were some "standard" examples that everyone uses as a basis for explaining the nature of a problem that requires the use of a buffer. What are some well-known problems in the real world that can see great benefits from using a buffer? Also, a little background or explanation as to why the problem benefits from using a buffer, and how the buffer would be implemented, would be insightful for understanding the concept!

  • Plays Well With Others - Influence versus Authority

    - by KKline
    Originally appearing on http://KevinEKline.com on Nov 13, 2010 You’ve probably found that the prefix “lead” is a fairly common occurrence in the technology world. We have “lead developers”, “lead DBAs”, “lead architects”, and “lead consultants”. Yet, we don’t have “lead managers”, “lead directors”, or “lead VPs”. Why is that? Well, there are probably a number of different reasons for having “lead” technologist titles depending on who you ask. For example, the HR department might say that adding “lead”...(read more)

  • The Power of AJAX and How to Use it

    Since its conception in 2005, AJAX (Asynchronous Javascript and XML) has changed the web world as we know it today. It's helped websites evolve into RIAs (rich internet applications) by allowing webpages to make direct requests to a web server without reloading the page. This capability is vital in replicating the rich user experiences achieved in client applications. The purpose of this post is to help newcomers understand the different ways that AJAX can be used to create RIAs.

  • vJUG: Worldwide Virtual JUG Created

    - by Tori Wieldt
    London Java Community leader and technical evangelist Simon Maple has created a Meetup called vJUG, with aim toward connecting Java Developers in the virtual world. The aim for vJUG is: Get technical leaders from around the world to present to the vJUG members (without travel cost concerns!). Work with local JUGs to provide worldwide content to their members and help JUGs present to a worldwide audience. Provide content to devs without access to a local JUG. Be a hub that will stream content from other JUG sessions live.  The vJUG is not intended to replace local JUG efforts. "The vJUG can never be, and will never be, as vibrant and valuable to its members as a proper local JUG can. Why? Because the true value in JUG meetings are the face to face interactions and personal networking," said Maple. "However, many people do not have access to a really active JUG with great speakers and awesome content. Or, like me, the closest JUG is about 90 mins away." WebEx and Google Hangouts are great, Maple explained, he hopes vJUG will provide more coordination of online events.  Maple hopes that in the future, vJUG will provide An Events calendar with reminders and links to up coming meetings. A Newsletter with what's coming up and links to previous sessions. Coordination of links to IRC channels which are active during presentations (to create a feeling of virtual community). Comments and forums around sessions and presentations A place where physical JUGs could advertise their sessions (i.e. a NY JUG event) to a worldwide audience, when streamed, via an event that people can sign up to. A common Webex or Hangout. Maple encourages both people who need a JUG and existing JUG members to join vJUG. "I'm looking forward to talking with many of you one to get members, speakers, and JUG support!" Join vJUG now! (I sense a need for a logo...)

  • Why occlusion is failing sometimes?

    - by cad
    I am rendering two cubes in the space using XNA 4.0 and occlusion only works from certain angles. Here is what I see from the front angle (everything ok) Here is what I see from behind This is my draw method. Cubes are drawn by serverManager and serverManager1 protected override void Draw(GameTime gameTime) { GraphicsDevice.Clear(Color.CornflowerBlue); switch (_gameStateFSM.State) { case GameFSMState.GameStateFSM.INTROSCREEN: spriteBatch.Begin(); introscreen.Draw(spriteBatch); spriteBatch.End(); break; case GameFSMState.GameStateFSM.GAME: spriteBatch.Begin(SpriteSortMode.Deferred, BlendState.AlphaBlend); // Text screenMessagesManager.Draw(spriteBatch, firstPersonCamera.cameraPosition, fpsHelper.framesPerSecond); // Camera firstPersonCamera.Draw(); // Servers serverManager.Draw(GraphicsDevice, firstPersonCamera.viewMatrix, firstPersonCamera.projMatrix); serverManager1.Draw(GraphicsDevice, firstPersonCamera.viewMatrix, firstPersonCamera.projMatrix); // Room //roomManager.Draw(GraphicsDevice, firstPersonCamera.viewMatrix); spriteBatch.End(); break; case GameFSMState.GameStateFSM.EXITGAME: break; default: break; } base.Draw(gameTime); fpsHelper.IncrementFrameCounter(); } serverManager and serverManager1 are instances of the same class ServerManager that draws a cube. The draw method for ServerManager is: public void Draw(GraphicsDevice graphicsDevice, Matrix viewMatrix, Matrix projectionMatrix) { cubeEffect.World = Matrix.CreateTranslation(modelPosition); // Set the World matrix which defines the position of the cube cubeEffect.View = viewMatrix; // Set the View matrix which defines the camera and what it's looking at cubeEffect.Projection = projectionMatrix; // Enable textures on the Cube Effect. this is necessary to texture the model cubeEffect.TextureEnabled = true; cubeEffect.Texture = cubeTexture; // Enable some pretty lights cubeEffect.EnableDefaultLighting(); // apply the effect and render the cube foreach (EffectPass pass in cubeEffect.CurrentTechnique.Passes) { pass.Apply(); cubeToDraw.RenderToDevice(graphicsDevice); } } Obviously there is something I am doing wrong. Any hint of where to look? (Maybe z-buffer or occlusion tests?)

  • How do I create weapon attachments?

    - by Tron86
    My question is; I am developing a game for XNA and I am trying to create a weapon attachment for my player model. My player model loads the .md3 format and reads tags for attachment points. I am able to get the tag of my model's hand. And I am also able to get the tag of my weapon's handle. Each tag I am able to get the rotation and position of and this is how I am calculating it: Model.worldMatrix = Matrix.CreateScale(Model.scale) * Matrix.CreateRotationX(-MathHelper.PiOver2) * Matrix.CreateRotationY(MathHelper.PiOver2); Pretty simple, the player model has a scale and its orientation(it loads on its side so I just use a 90 degree X axis rotation, and a Y axis rotation to face away from the camera). I then calculate the torso tag on the lower body, which gives me a local coordinate at the waist. Then I take that matrix and calculate the tag_weapon in the upper body. This gives me the hand position in local space. I also get the rotation matrix from that tag that I store for later use. All this seems to work fine. Now I move onto my weapon: Matrix weaponWorld = Matrix.CreateScale(CurrentWeapon.scale) * Matrix.CreateRotationX(-MathHelper.PiOver2) * TagRotationMatrix * Matrix.CreateTranslation(HandTag.Position) * Matrix.CreateRotationY(PlayerRotation) * Matrix.CreateTranslation(CollisionBody.Position) * You may notice the weapon matrix gets rotated by 90 degress on the X axis as well. This is because they load in on their sides. Once again this seems pretty simple and follows the SRT order I keep reading about. My TagRotation matrix is the hand's rotation. HandTag.Position is its position in local space. CreateRotationY(PlayerRotation) is the player's rotation in world space, and the CollisionBody.Position is the player's world location. Everything seems to be in order, and almost works in game. However when the gun spawns and follows the player's hand it seems to be flipped on an axis every couple frames. Almost like the X or Y axis is being inversed then put right back. Its hard to explain and I am totally stumped. Even removing all my X axis fixes does nothing to solve the problem. Hopefully I explained everything enough as I am a bit new to this! Thanks!
