• Producing a smooth mesh from density cloud and marching cubes

  - by Wardy

  Based on my results from this question I decided to build myself a 3D noise map containing float values in place of my existing boolean point values. The effect I'm trying to produce is something like this, rather than typical rolling hills; which should explain the "missing cubes" in the image below. If I render my density map in normal "minecraft mode" (1 block per point in the density map) varying the size of the cube based on the value in my density map (floats in the range 0 to 1) I get something like this: I'm now happy that I can produce a density map for the marching cubes algorithm (which will need a little tweaking) but for some reason when I run it through my implementation it's not producing what I expect. My problem is that I'm getting something like the first image in this answer to my previous question, when I want to achieve the effect in the second image. Upon further investigation I can't see how marching cubes does the "move vertex along the edge" type logic (i.e. the difference between the two images on my previous link). I see that it does do some interpolation, but I'm not convinced I have the correct understanding of what I think it should do, because the code in question appears to give the same result regardless of whether I use boolean or float values. I took the code from here which is a C# implementation of marching cubes, but instead of using the MarchingCubesPrimitive I modified it to accept an object of type IDrawable, containing lists for the various collections (vertices, normals, UVs, indices), the logic was otherwise untouched. My understanding is that given a very low isovalue the accuracy level of the surface being rendered should increase, so in short "less 45 degree slows more rolling hills" type mesh output. However this isn't what I'm seeing. Have I missed something or is the implementation flawed and need to be fixed? EDIT: A little more detail on what I am seeing when I "marching cube" the data. Ok so firstly, ignore the fact that the meshes created by the chunks don't "connect" (i'll probably raise another question about this later). Then look at the shaping of the island, it's too ... square, from the voxels rendered as boxes you get the impression there's a clean soft gradual hill and yet from the image there are sharp falling edges even in the most central areas where the gradient in the first image looks the most smooth. The data is "regenerated" each time I run this so no 2 islands come out the same, and it's purely random so not based on noise, but still, how can it look so smooth in 1 image and so not smooth in the other?

• Day 1 - Finding Like Minds

  - by dapostolov

  So, is being a Game Developer any different from being an IT Developer? I picture a poorly lit environment where I get to purchase my own desk lamp; I'm thinking one of those huge lava lamps that pump out so much heat you could fry an egg on it. To my right: a "great wall" of empty coke cans dwarf me. Eating my last slice of pizza I look across my desk to see a fellow developer with a smug look on his face;  he's just coded his latest module for the game and it looks like he's in nirvana. My duty, of course, is to remind him to keep focused on the job at hand. So, picking up my trusty elastic and aerodynamically crafted paper bullet I begin a 10 minute war of welts and laughter which is promptly abrupted by our Project Manager demanding more details from our morning Scrum meeting. After providing about 5 minutes of geek speak and several words of comfort to make his eyes glaze over...it hits me, the idea for the module...beckoning my developer friend over, we quickly shoo the Project Manager away and begin our brainstorming frenzy ... now, where'd I put that full can of coke? OK. OK. This isn't probably the most ideal game developer environment, but it definitely sounds fun to me...and from what I gather is nothing like most game development companies. But I'm not doing this blog series to "go pro"; like I stated in my first post I want to make a 2D game from an idea my best friend and I drummed up long, long ago. I'm in this for the passion AND I want to see how easy it is for us .Net Developers to create a game. So where do I start? Where can I find like minded individuals? What technologies are there? What do I need to make a video game? The questions are endless....AND...since I already have an idea ... lets start with ... Technology (yes, I'm a geek, live with it...) Technology OK. Predominantly, games are still made in C++ or even C. I'm not sure how much assembly code is floating around lately, however, that is not my concern. I do know C / C++ from my past, enough to even get me by, but I'm mainly interested in a recent, not-so-new, technology called XNA. What is XNA? XNA allows us .Net Developers to make 2D / 3D games for windows, Xbox*, and Windows Mobile 7*. * = for a nominal fee *cough* The following link is your one stop shop to XNA game development: http://creators.xna.com/en-US/education/gettingstarted The above site hosts information such as: - getting started - a sample/instructional shooter game in 2D / 3D with code (if I'm taking too long for you in this blog series) - downloads - starter kits... http://creators.xna.com/en-US/education/starterkits/ And of course...forums. You can also subscribe and pay for their premium membership which gets you some pretty awesome tutorials, resources, downloads, and premium community support. Some general Wiki information about XNA: http://en.wikipedia.org/wiki/XNA_%28Microsoft%29 Community Support OK. Let's move on to industry and community support. Apart from XNA, there are some really cool sites out there, I just haven't found all of them yet. However, I found a really cool Game Development website called Gamastura. You can click on the following link to get you there: http://www.gamasutra.com/ The site is 100% dedicated to "The Art & Business of Making Games". Armed with blogs, twitter, jobs/resumes and most importantly industry news; one could subscribe to the feed and got lost in the wealth of information it provides. On a side note: I remember Gamasutra being around when my best friend and I wanted to make a video game...meaning, they've been around for a while now. I think the most beneficial aspect of this site is to understand the industry you want to get into. Otherwise, it's just a cool site to keep up to date with the industry in general. Another Community Support option is LinkedIn. Amongst the land of extremely bloated achievements and responsibilities lay 3 groups (that I have found) that deal with game development.: http://www.linkedin.com/groups?gid=59205 - Game Developers http://www.linkedin.com/groups?gid=824817 - DirectX Game Developer Network http://www.linkedin.com/groups?gid=756587 - DirectX Developers The Game Developers group in LinkedIn is by far the most active of the three and could possibly provide a wealth of support. What I've done thus far: - I lightly researched the XNA technology - I looked around for some community sites to assist me - I downloaded the XNA Game Studio 3.1 on my PC and installed it on my IDE - I even tried both tutorials! http://creators.xna.com/en-US/education/gettingstarted/bgintro/chapter1   Best Regards D.

• Effects to make a speeding spaceship look faster

  - by Badescu Alexandru

  I have a spaceship and I've created a "boost" functionality that speeds up my spaceship, what effects should I implement to create the impression of high speed? I was thinking of making everything except my spaceship blurry but I think there would be something missing. Any ideas? Btw. I am working in XNA C# but if you aren't familiar to XNA describing some effects is still useful. The Game is 3d and i've attached some printscreens of the game This is in normal mode ( none boosted ) and here is the boosted mode ( the craft speeds up forward while the camera speeds in its normal speed , the non boosted speed )

• Lighting get darker when texture is aplied

  - by noah

  Im using OpenGL ES 1.1 for iPhone. I'm attempting to implement a skybox in my 3d world and started out by following one of Jeff Lamarches tutorials on creating textures. Heres the tutorial: iphonedevelopment.blogspot.com/2009/05/opengl-es-from-ground-up-part-6_25.html Ive successfully added the image to my 3d world but am not sure why the lighting on the other shapes has changed so much. I want the shapes to be the original color and have the image in the background.

• Weekend Project: Make Your Own Ferromagnetic Fluid

  - by Jason Fitzpatrick

  Experiments this simple and fun give you no reason to leave all science-based goofing off to the professionals: whip up a beaker of ferromagnetic fluid to capture magnetic waves in motion. The premise is simple: by combing a viscous liquid (in this case vegetable oil) with a magnetic powder (in this case MICR copy toner) and introducing a strong magnetic source (such as neodymium rare earth magnets), you can actually see the magnetic waves in physical space. It’s like the old magnetic filings on the table top trick, but in 3D. Check out the video above to see how you can mix up a batch of your own.

• Lighting a Voxel World Realistically

  - by sharethis

  I am new to game development and never implemented a complicated (and realistic) lighting. My game uses a 3d voxel terrain world (like Minecraft). To hold the data I use octrees. My goal is to render a more realistic world scene like in most voxel games. For that I want to use a bezier algorithm to round out the blocky world. Assume that I already have a large generated polygon of my terrain (or some of them). I heard of some techniques like volumetric light, global illumination, ... What approaches of a very realistic lighting are there for my "organic shaped" voxel game?

• Rendering performance in FlasCC + UDK when compared to Stage3d and UDK on Windows?

  - by Arthur Wulf White

  Adobe recently released the Flash C++ Compiler, which UDK uses to target Flash Player. Developers can now access UDK for browser applications. Does this mean greater performance than using a Stage3D engine (Away3D 4) and how much of a noticeable difference in performance would it make in rendering speeds? Is there any benchmark you could propose that would allow to compare them fairly? I am asking this to help myself understand the consequences in performance for deciding to use UDK in a browser based game. I would also like to know how it compares with UDK running natively in Windows? I am not asking which technology to use or which is better. Only interested in optimizing rendering speed in a 3d browser game with flash.

• Resources for 2D rendering using OpenGL?

  - by nightcracker

  I noticed that there is quite some difference between 3D and 2D rendering using OpenGL, the techniques are different - pixel-perfect placing is a lot more desirable, among other things. Are there any good (complete) references on using OpenGL for rendering 2D graphics? There are quite a few "tutorials" around on the net that help you open a window, set up a half-decent environment and draw a sprite, but no real good information on rotation, blending, lightning, drawing order, using the z-buffer, particles, "complex" primitives (circles, stars, cross symbols), ensuring pixel-perfect rendering, instancing and many other staple 2D effects/techniques. Any books, great blogs, anything? Any particular awesome libraries to read?

• Problems with HP laptop

  - by Jan

  So the problem is...every time I reboot or shutdown laptop and when the laptop is booting again I get screen (before loading OS) that HP discovered overheating and system went into hibernate. But the point is that laptop is not overheating nor going into hibernate by itself. Also becouse of the hybrid graphic cards I cannot install additional drivers. Desktop resolution and all works perfectly but I cannot use unity 3D also openGL doesn't work as it should (with cairo docks) As i've read some posts, people say that switcheero doesn't work on 12.04 so I haven't tried it.

• Is it normal to not have desktop effects after installing on an Asus N53S?

  - by Fabzter

  I've just installed 11.10 and so far so great, except I just discovered (after looking at another installation) I'm missing some effects. First of all, I am using unity 3d (I chose ubuntu at the login menu), and have already the correct nvidia drivers. Yet, my launcher is the same from unity 2d, the same as the app switcher, and when dragging windows to screen corners, they don't get grabbed. This "error" was present since the begining, so I was not able to detect it. Please help, I want to have an ubuntu experience as nice as everyone else. EDIT 1: I'm using an Asus N53S. My graphic card is Nvidia geforce GT540M. It says cuda, if that matters.

• How is game development different from other software development?

  - by Davy8

  For a solid general purpose software developer, what specifically is different about game development, either fundamentally or just differences in degree? I've done toy games like Tic-tac-toe, Tetris, and a brute-force sudoku solver (with UI) and I'm now embarking on a mid-sized project (mid-sized for being a single developer and not having done many games) and one thing I've found with this particular project is that separation of concerns is a lot harder since everything affects state, and every object can interact with every other object in a myriad of ways. So far I've managed to keep the code reasonably clean for my satisfaction but I find that keeping clean code in non-trivial games is a lot harder than it is for my day job. The game I'm working on is turn-based and the graphics are going to be fairly simple (web-based, mostly through DOM manipulation) so real time and 3d work aren't really applicable to me, but I'd still be interested in answers regarding those if they're interesting. Mostly interested in general game logic though. P.S. Feel free to retag this, I'm not really sure what tags are applicable.

• Issue with Mapping Textures to Models in Blender

  - by Passage

  I've been trying to texture a model using Blender, but when I draw on the UV Editor it doesn't show up on the model, and I can't draw on the model itself. I've tried saving the image and the 3D View is set to Texture. Everything seems to be in order and I've followed several tutorials, but none of them seem to work with the version I'm using (2.64-- update was necessary for import plugin) and I'm absolutely stumped. How can I draw textures to the model? If not within Blender itself, how do I export/import the textures? EDIT: Vertex Paint works, though it is insufficient for my purposes. In addition, moving to the rendered view produces a solid-color model with none of the applied textures.

  I have one doubt about world game developing. I want to do a kind of platform game mixed with RPG (Side Scroll). What's the best to draw the world, - Draw everything than use the camera to move around the world - Draw just what you see as the player moves draw the new stuff. I'm new at this and didn't had any course for it. So if anyone can help me thanks :) PS: Any recommendation to learning game concept, like drawing world theory, play etc..

• Unity 5.1 audio issues (no sound in back channels)

  - by N0xus

  I've trying to bring in surround sound audio into my project. I've set my computer up to run in 5.1 and when I play a 6 channel audio through windows media player (it's a test audio that does left speaker, right speaker etc) it works fine. However, when I run it through Unity, all I get is the front 3 channels. I've set it in the Edit - project settings - audio to be 5.1 in there. I even set it in code with following: void Start() { AudioSettings.speakerMode = AudioSpeakerMode.Mode5point1; } How ever, when I run a debug line of: print ( AudioSettings.driverCaps); It tells me that Unity is only playing in stereo. Is there something I'm still not doing? I should also add I've ran 10 different tests using the 3D audio pan and spread options. I've set both to either being fully off, half way on and full. Still the same results.

  I have an idea for a game that has a potential, but I'm not a programmer. How to tell this to development companies without being my idea stolen? All I want from the company is first to watch a 3-minute long video presentation about my idea and if they see fantasy in it then we can talk about the details. I have already sent an e-mail to several big companies that have the expertise needed to code the game, they haven't answer me. Actually the idea is nothing fancy, no 3D, but fun and unique.

• Browser-based MMOs (WebGL, WebSocket)

  - by Alon

  Do you think it is techniclly possible to write a fully-fledged 3D MMO client with Browser JavaScript - WebGL for graphics, and WebSocket for Networking? Do you think future MMOs (and games generally) will wrriten with WebGL? Does today's JavaScript performance allow this? Let's say your development team was you as a developer, and another model creator (artist). Would you use a library like SceneJS for the game, or write straight WebGL? If you would use a library, but not SceneJS, please specify which. Thanks!

Please use this software in a 64bits session. (Please use Ubuntu-Secure-Remix-64bits (www.sourceforge.net/p/ubuntu-secured) which contains a 64bits-compatible version of this software.) This will enable this feature. =================== Final advice in case of recommended repair The boot files of [Ubuntu 12.04.1 LTS] are far from the start of the disk. Your BIOS may not detect them. You may want to retry after creating a /boot partition (EXT4, >200MB, start of the disk). This can be performed via tools such as gParted. Then select this partition via the [Separate /boot partition:] option of [Boot Repair]. (https://help.ubuntu.com/community/BootPartition) =================== Default settings Recommended-Repair This setting would reinstall the grub2 of sda6 into the MBR of sda, using the following options: kernel-purge Additional repair would be performed: unhide-bootmenu-10s fix-windows-boot =================== Settings chosen by the user Boot-Info This setting will not act on the MBR. No change has been performed on your computer. See you soon! pastebinit packages needed dpkg-preconfigure: unable to re-open stdin: No such file or directory pastebin.com ko (), using paste.ubuntu Please report this message to [email protected] Any help would be great, I'm really missing Ubuntu (hate being stuck in the Windows world).

• HP Pavilion g6 1190sm laptop has overheat/hibernation/graphics issues

  - by Jan

  Every time I reboot or shutdown my laptop, while the laptop is booting again I get a screen (before loading the OS) that HP discovered overheating and system went into hibernation. But the point is that the laptop is not overheating nor going into hibernation by itself. Also, because of the hybrid graphics card I cannot install additional drivers. Desktop resolution and all works perfectly but I cannot use Unity 3D. Also, OpenGL doesn't work as it should (with Cairo Dock). As I've read some posts, people say that vgaswitcheroo doesn't work on 12.04 so I haven't tried it.
