RT/Shader Makes Shaders Easy

RTzen, Inc will be launching a shader development tool, RT/Shader, at GDC. The tool allows one to create high-level shader programs visually--by assembling visual elements such as textures and lighting effects. The resulting shaders are previewed in realtime for immediate feedback. RT/Shader supports the Direct3D HLSL and Nvidia's Cg shading languages, and includes a code editor in its IDE for viewing and tweaking the code that results from its calculations. The program is priced at $1,995.
