What books or webpages are out there for learning how to write glsl shaders, for use in 3D?
http://en.wikibooks.org/wiki/Programming:OpenGL Has anyone read this one OpenGL(R) Shading Language (2nd Edition) http://tinyurl.com/ysun6z Are there any third party applications for writing glsl shaders that can be easially ported over to PD?
