Now, for around $10 000, you can get the speed of a small cluster in a desktop machine, by using the untapped potential of the GPU (Graphics Processing Unit). A machine with four high end GPUs from NVIDIA has up to four teraflops of processing power, equivalent to around 60 of the fastest CPUs.

FfA's latest release of SVI Pro uses the GPU in three different ways:
1. For general visualisation
2. For interactive (visual) computing
3. For GPU accelerated volume processing

Optix vs. Vista/7 issue persists  >:(

In this article, I discuss mixing CUDA and OpenGL by utilizing a PBO (Pixel Buffer Object) to create images with CUDA on a pixel-by-pixel basis and display them using OpenGL. A subsequent article in this series will discuss the use of CUDA to generate 3D meshes and utilize OpenGL VBOs (Vertex Buffer Objects) to efficiently render meshes as a colored surface, wireframe image or set of 3D points. All demonstration code compiles and runs under both Windows and Linux.

3D-Tech News Around The Web / Shader Toy, an online shader editor
« on: January 26, 2010, 05:46:07 PM »
It's using the pretty new WebGL specification to allow you to edit GLSL shaders. Because the tool is online you don't need to install anything (this will be true the day all browsers have support for WebGL - for the time being read the not in the end of the post). In the other hand, it comes with lots of interesting shaders. Raymarching, procedural distance fields, metaballs, tunnels, deformations, postprocessing effects, .... Just load them and have a look to learn how these techniques work, or start modifying them to make your own shader.

I think this tool is ideal when you have an idea and want to sketch it, or want to play a bit with shaders, but you don't have your OpenGL framework handy, nor you have textures or even a compiler at all. Instead, wherever you are, in your vacations trip, at your mum's, you just need a browser. Connect to the Shader Toy page, load one of the presets shaders, and start playing around. As simple as that! You can use any online image to feed the 4 texture units in the shader by providing Shader Toy with the url of the image. I even created some usefull "noise" textures for you, and there are quite a few "famous" demos in the presets, donated by several demoseners. Check them out.


- four texture input from online images
- mouse input to feed your shader parameters with some life data
- quick compile with ALT TAB shortcut
- framerate monitor
- viewport resolution selector
- glsl-es help
- time control
- lots of cool presets, for free!

Coming soon:

- syntax highlight
- video input (feed a texture unit with online video!)
- flexible parameter input with custom user js functions
- advanced timeline control
- multithreaded render
- cubemaps
- submit/save your own shaders and presets


** Note: most browsers don't implement the WebGL specification yet. You need the nightly build of Firefox (3.7), Chrome or Safari to use Shader Toy. So far I have successfully tested it Firefox 3.7 and Chrome 4.0 under Windows, Firefox 3.7 under Linux. I have been reported that it works in Safari under Mac too. Please follow the instructions in for installation.

** Note: ShaderToy was made for helping making "flat shaders" only, it was never intended to be a RenderMonkey-clone where you can load 3d meshes. ShaderToy is about filling pixels only. Of course, that doesn't mean you can only do 2d, nothing prevents you from writing raytracers right? - check the presets.

3D-Tech News Around The Web / Microsoft Office 2010 requires "newer" GPUs
« on: January 25, 2010, 05:13:02 PM »
Why is there a new graphics processor requirement?

If you’ve checked out Office 2010’s full system requirements, you’ve probably noticed the new graphics processor (GPU) requirement, and might be wondering what that’s all about. Another piece of feedback we received after releasing Office 2007 is that customers were interested in harnessing more of the potential of their PCs. Many computers in 2007 and most computers today have graphics processors separate from the CPU (this doesn’t necessarily mean a dedicated graphics card; for example, most laptops don’t have a physical graphics card, but do come with a graphics processor). If your computer has a GPU, it lets us perform graphics rendering tasks (like drawing charts in Excel, or transitions in PowerPoint) in the GPU instead of in the CPU, which parallelizes work and speeds up performance. This is particularly relevant for users of PowerPoint 2010, which will introduce some awesome new graphics and video integration features (more info at the PowerPoint team blog).

We chose to design for Microsoft® DirectX® 9.0c compliant graphics processors with 64 MB video memory. These processors were widely available in 2007, and most computers available today include a graphics processor that meets or exceed this standard. However, like our CPU and RAM requirements, this requirement is targeted for typical tasks – if you intensively use graphics features, you’ll benefit from a more powerful GPU.

3D-Tech News Around The Web / OIT/A-buffer DirectX 11 demo
« on: January 15, 2010, 09:18:32 AM »
OIT/A-buffer demo.
Requires Microsoft Windows 7 (or Vista SP 2) and DirectX 11 graphics hardware.

This demo shows accurate blending of multiple surfaces using per-pixel depth sorting.
Uses DirectCompute 11 for A-buffer technique and stencil routing for K-buffer.

Left mouse:    Click and rotate trackball.
Mouse wheel:   Zoom in/out.
Space:         Switch beetween standard hardware blending, A-buffer blending and K-buffer blending.
Numpad +/-:    Add/decrease number of blended planes (cards).

By default, standard blending without sorting is performed.
GDI text drawing really slow down FPS, so hints are displayed only for 2 seconds.
