Inspired by the summer Olympics taking place this year, ShaderTech.com is hosting a shader contest this summer with three categories: Materials & Environmental Effects, Image Processing & NPR Effects, and Thinking Outside the Box (this category includes GPGPU applications!).

With over $20,000 worth of prizes available, the Shader Triathlon is a great way to show off your shader skills. Participants can win gold, silver, and bronze prizes for each category, as well as the grand prize: 3ds max, RT/Shader, and a GDC 2005 Gigapass! In addition, all entrants will be entered into a random drawing for the following prizes: 3ds max, RT/Shader, and GPU Gems books.

The Shader Triathlon is sponsored by NVIDIA, discreet, RTzen, and the Game Developers Conference 2005. (ShaderTech.com Shader Triathlon.

ATI's Ashli version 1.4.0 has been released and is available for download from: Ashli Home. Ashli is a toolkit intended to assist developers exploring programmable shading on GPUs. It supports a reasonable subset of OpenGL (GLSL), Microsoft's DirectX (HLSL) and RenderMan shading languages. Ashli's significant contribution is in hardware resource virtualization, segmenting a complex shader program into GPU realizable streams. The posted Ashli viewer application demonstrates the use of shader partitions in a multi-pass rendering context. Ashli outputs both metadata and code, orthogonal to any of the languages supported. Targets include OpenGL ARB_vertex_program and ARB_fragment_program, and DirectX 9.0 Vertex Shader and Pixel Shader versions 2.0 and 2.X API's. Optionally, Ashli emits a unified Microsoft FX file format, embedding progressive techniques of state and code sections. (Ashli 1.4.0)
