Humus has released a new Direct3D demo. Interior mapping is a technique that renders the interior of buildings without requiring additional geometry. Everything is done in the pixel shader. The advantage is that when you’re rendering large cities you can draw all those buildings as simple boxes. This demo requires DirectX 10.1 and Windows Vista SP1.

Source Code and binaries: Interior Mapping Demo

Update – 2008.08.17
Demo has been updated with around 80% of performance boost.

NVIDIA ShaderPerf is a command-line shader profiling utility and C API that reports detailed shader performance metrics for a wide range of GPUs.

ShaderPerf wokrs with GLSL vertex and fragment programs, HLSL vertex and pixel shaders and Cg shaders.

ShaderPerf 2.0 includes several new features:
* GeForce 8 series support
* Pixel Shader Differencing
* Vertex Shader Analysis

ShaderPerf outputs the following for any shader that you analyze:
* Cycle count
* Register usage
* Driver-optimized shader instruction list
* Vertex and pixel throughput estimates

[English]
Shader Maker is a simple, cross-platform GLSL editor. It works on Windows, Linux, and Mac OS X. It provides the basics of a shader editor, such that students can get started with writing their own shaders as quickly as possible. This includes: syntax highlighting in the GLSL editors; geometry shader editor (as well as vertex and fragment shader editors, of course); interactive editing of the uniform variables; light source parameters; pre-defined simple shapes (e.g., torus et al.) and a simple OBJ loader; and a few more.

[French]
Shader Maker est un editeur GLSL multi-plateformes (Windows, Linux et MacOS). Il inclue la coloration syntaxique, des ├ęditeurs pour les vertex, geometry et pixel shaders, ├ędition interactives des variables uniformes.
