Member Function Documentation

virtual void vl::ProjViewTransfCallback::programFirstUse	(	const Renderer *	caller,
		const GLSLProgram *	glsl,
		const Transform *	transform,
		const Camera *	camera,
		bool	first_overall
	)		[pure virtual]

This function is called whenever a new GLSLProgram (or the NULL one, i.e.

the fixed function pipeline) is being activated for the first time in the current rendering. This callback is most useful to initialize the GLSLProgram with the current projection and view matrices, besides the current Actor's transform.

Parameters:

caller	The Renderer object calling this function.
glsl	The GLSLProgram being activated. If NULL the fixed function pipeline is being activated.
transform	The transform of the current Actor being rendered.
camera	The Camera used for the rendering from which you can retrieve the projection and view matrices.
first_overall	If true it means that the rendering has just started. Useful if you want to initialized your callback object.

Implemented in vl::ProjViewTransfCallbackStandard.

virtual void vl::ProjViewTransfCallback::programTransfChange	(	const Renderer *	caller,
		const GLSLProgram *	glsl,
		const Transform *	transform,
		const Camera *	camera
	)		[pure virtual]

This function is called whenever the Transform changes with respect to the current GLSLProgram (including the NULL one, i.e.

the fixed function pipeline). This callback is most useful to update the GLSLProgram with the current Actor's transform matrix.

Parameters:

caller	The Renderer object calling this function.
glsl	The GLSLProgram being activated. If NULL the fixed function pipeline is being activated.
transform	The transform of the current Actor being rendered.
camera	The Camera used for the rendering from which you can retrieve the projection and view matrices.

Implemented in vl::ProjViewTransfCallbackStandard.
