Interface GlslProgram

All Known Implementing Classes:
CompiledProgram
public interface GlslProgram
A GLSL program, which links multiple shaders together, for example vertex shader and a fragment shader. Update the GlslProgramDef and GlslShaderDef enums whenever you want to add a new GLSL program and its shaders. Update the GlslBufferGroup enum to define their buffers.
