(requires GL 4.3 or ARB_compute_shader)Ī program object can combine multiple shader stages (built from shader objects) into a single, linked whole. (requires GL 4.0 or ARB_tessellation_shader) Tessellation Control and Evaluation Shaders: GL_TESS_CONTROL_SHADER and GL_TESS_EVALUATION_SHADER.The OpenGL rendering pipeline defines the following shader stages, with their enumerator name: Shaders are written in the OpenGL Shading Language. Each stage has a set of inputs and outputs, which are passed from prior stages and on to subsequent stages (whether programmable or not). Each of these sections, or stages, represents a particular type of programmable processing. The rendering pipeline defines certain sections to be programmable.
