An AbstractTask to set transformation matrices in programs.

Constructor & Destructor Documentation

ork::SetTransformsTask::SetTransformsTask	(	const string &	screen,
		QualifiedName	m,
		const char *	t,
		const char *	ltow,
		const char *	ltos,
		const char *	ctow,
		const char *	ctos,
		const char *	stoc,
		const char *	wtos,
		const char *	wp,
		const char *	wd
	)

Creates a new SetTransformsTask.

Parameters:

	screen	the "screen" node to be used for transformation involving the "screen" space. An empty name means the "real" screen space of the camera node.
	m	a "node.module" qualified name. The first part specifies the scene node that contains the module. The second part specifies the name of a module in this node. This module is used to find the uniforms that this task must set.
	t	the vec2 uniform that contains time of current frame and time elapsed since last frame.
	ltow	the mat4 uniform to be set to the local to world transformation.
	ltos	the mat4 uniform to be set to the local to screen transformation.
	ctow	the mat4 uniform to be set to the camera to world transformation.
	ctos	the mat4 uniform to be set to the camera to screen transformation.
	stoc	the mat4 uniform to be set to the screen to camera transformation.
	wtos	the mat4 uniform to be set to the world to screen transformation.
	wp	the vec3 uniform to be set to the world coordinates of the origin of the local frame.
	wd	the vec3 uniform to be set to the world coordinates of the unit z vector of the local frame.
