static GLuint prepare_materials	(	GLcontext *	ctx,
		struct vertex_buffer *	VB,
		struct light_stage_data *	store
	)			[static]

Prepare things prior to running the lighting stage.

Return number of material attributes which will track vertex color.

static GLboolean run_lighting	(	GLcontext *	ctx,
		struct tnl_pipeline_stage *	stage
	)			[static]

static void update_materials	(	GLcontext *	ctx,
		struct light_stage_data *	store
	)			[static]

In the case of colormaterial, the effected material attributes should already have been bound to point to the incoming color data, prior to running the pipeline.

This function copies the vertex's color to the material attributes which are tracking glColor. It's called per-vertex in the lighting loop.

static void validate_lighting	(	GLcontext *	ctx,
		struct tnl_pipeline_stage *	stage
	)			[static]
