Program Class Reference

Description

Represents the configuration of an OpenGL pipeline.

It contains all important stages of the OpenGL Pipeline:

• Programmable: VertexShader, FragmentShader
• Configureable: PrimitiveProcessing, PerFragmentProcessing

The vertex and fragment shader are neccessary to create a valid Program. To use the Program you have to prime it.

Member Function Documentation

void create	(	VShader &	vs,
		FShader &	fs
	)

Links the shaders and creates the Program.

Note

Both shaders need to be already compiled!

Parameters

vs	vertex shader
fs	fragment shader

void prime

(

std::function< void(HotProgram &)>

func

)

Primes the Program in order to use it.

Binds the program and applies all attributes of the configurable pipline stages. You need a HotProgram to draw something.

Parameters

func	A functor that accepts a HotProgram& as parameter
