glslv - OpenGL vertex profile for the OpenGL Shading Lanauge (GLSL) glslv This OpenGL profile corresponds to the per-vertex functionality introduced by the OpenGL Shading Language. The compiler output for this profile conforms to the language grammar defined by the OpenGL Shading Language specification. Requires OpenGL support for OpenGL 2.0.

OpenGL Extension Specifications
http://www.opengl.org/documentation/specs/version2.0/glspec20.pdf http://www.opengl.org/documentation/glsl/ http://www.opengl.org/registry/doc/GLSLangSpec.Full.1.20.8.pdf GLSL version to target. Supported versions are 100, 110, 120, 130, 140 and 150. Use user-defined varying instead of gl_TexCoord. Use ATI_draw_buffers extension for MRT. Use EXT_gpu_shader4 extension where useful. The Cg half and fixed data types are both mapped to float because GLSL lacks first-class half and fixed data types.

UNIFORM INPUT SEMANTICS
The Cg profiles for GLSL provide access to all the uniform constants and variables documented in Section 7.4 (Built-in Constants) and 7.5 (Built-in Uniform State) respectively of the OpenGL Shading Language specification found at: http://www.opengl.org/documentation/glsl/ http://www.opengl.org/registry/doc/GLSLangSpec.Full.1.20.8.pdf Example: glslv void main(float4 position : POSITION, out float4 opos : POSITION) { opos = mul(gl_ModelViewMatrix, position); }
