Hardware of the Casual Gamer

Unity3D has publihed the result of their hardware survey. Unity3D targets the casual gamer and here are some pictures about what is graphics card of the casual gamer:

Casual gamers are really not interested to performance since around 3% of them haven’t graphics drivers… Most of the graphics cards are integrated chipsets (Intel, S3) and the first decent graphics card is the GeForce 8600 with is ranked 15.

John Carmack Loves its iPhone

John Carmack loves his iPhone and wants to make a game for that device that would be a graphical tour de force (I like this kind of french expressions in english sentences). I guess, given the limited hardware features of the iPhone, Carmack likes this kind of challenge. So let’s prepare for the next accelerometer-controlled Doom-like…

DirectX 9 to DirectX 11, where did 10 go?

Here is an analysis, by a game developer called Susheel, of the new things that DirectX 11 will bring.

Read the complete analysis HERE.

What is really interesting to see is the emergence of what Microsoft terms as the Compute Shader, no doubt a marketing speak for GPGPU which they claim will allow the GPU, with it’s awesome power to be used for more than just graphics, which smells like CUDA (Compute Unified Device Architecture) to me.

Issues like multi-threaded rendering/resource handling are things that were long time coming and yes, it’s a good thing we will finally see them in the newer version. It just makes my job as a game developer a whole lot easier. Most details on Shader Model 5.0 are pretty sketchy, so I won’t go into things like shader length and function recursion. However, I hope such issues are addressed satisfactorily in the newer shader model.

Microsoft is still fixated on releasing version 11 only for Vista, so don’t expect your XP machines to ever run DirectX 11 even if you buy brand new hardware.

OpenGL Bootcamp at the Big Nerd Ranch October 2008

Big Nerd Ranch announces the October 2008 session of OpenGL Bootcamp. This intensive 5-day training course will arm you with the knowledge to make your 2D and 3D visualizations fly! As problem sets explode in complexity, radical gains in performance have resulted from moving traditional graphics processing from the CPU to graphics hardware. If you are doing any work concerning graphics, then you must know OpenGL and this class is the fastest way to master the ideas and techniques of OpenGL programming. By taking full advantage of hardware acceleration, shaders, blending, textures and video we’ll help you get the most out of your data. Learn how OpenGL works, what functionality it does and does not provide, various optimization methods for both static and dynamic data, and much more. The course will provide libraries and frameworks for abstracting the operating system and allowing the student to focus solely on learning OpenGL.

DirectX 11 Details Emerge

Similar to DirectX 10, DirectX 11 will be available only on Windows Vista and future versions of Microsoft’s operating system. DirectX 11 will add new compute shader technology that Microsoft says will allow GPUs to be used “for more than just 3D graphics,” allowing developers to utilize video cards as parallel processors.

DirectX 11 will support tessellation, a feature which can potentially assist developers in making models appear smoother when seen up close. Multi-threaded resource handling is also incorporated, making it easier for games to utilize multi-core processors in a user’s machine.

Gamestudio v7.10 Released

Gamestudio/A7, the easy all-in-the-box game development system, announces the release of version 7.10.

Gamestudio homepage: www.3dgamestudio.com

Gamestudio is not a game engine, not a game editor, and not a game programming language. It’s all of them together. It contains all necessary tools for creating commercial-quality 3D or 2D games or realtime graphics applications right out of the box. It comes with a state-of-the-art 3D and 2D game engine, a level editor, a model and terrain editor, the lite-C script language with compiler, editor, and debugger, as well as thousands of ready-to-use elements, such as models, level prefabs or textures.

Arauna Ray Tracer

Arauna is a real-time ray tracer developed for game development. Being a real-time ray tracer, it is experimental, and does not yet deliver the performance needed to produce graphics of the same quality as modern games do using a GPU. However, in its class, it is one of the fastest (probably the fastest) renderer. Two games have been developed already using Arauna, both by students of the IGAD program of the NHTV University of Applied Sciences (Breda, The Netherlands).

DirectX 11 to be discussed in just weeks!

Microsoft will start talking about DirectX 11 in less than two weeks. his conference takes place on the 22 and 23 July in Seattle, Washington.

The big feature of DirectX 11 is tessellation / displacement while we also heard that multithreaded rendering and compute shaders are part of it. DirectX 11 also brings shader model 5.0 but we don’t know many details about it.

It looks like DirectX 11 will stick to rasterization as there is no any mentioning of Ray tracing support.
