Detailed Description

Encapsulates the uniform subroutine setting operations.

Requires OpenGL 4.0 or the GL_ARB_shader_subroutine extension.

Member Function Documentation

void oglplus::UniformSubroutines::Apply

(

const Preset &

preset

)

Applies the setting from a preset without changing the current setting.

Note

Only presets from the same instance of UniformSubroutines that saved them can be loaded or applied.

void oglplus::UniformSubroutines::Apply

(

void

)

Applies all changes made by Assign.

Assign

UniformSubroutines& oglplus::UniformSubroutines::Assign	(	const SubroutineUniform &	uniform,
		const Subroutine &	subroutine
	)

Assigns the subroutine to the subroutine uniform.

Note

This function does not apply the changes to the actual uniform variables in the stage of the program. Use Apply function to do this after the subroutines are assigned.

void oglplus::UniformSubroutines::Load

(

const Preset &

preset

)

Loads the setting of subroutine uniforms from a preset.

Note

Only presets from the same instance of UniformSubroutines that saved them can be loaded or applied.
