Detailed Description

A helper class to create a OpenGL geometry shader programs.

Child classes must call CompileGeometryShader() to compile a GL program including a geometry shader.

const [inline]

Provide the render primitive type for the input type of the associated geometry shader here.

This must be compatible, e.g. for DrawArray().
