Function Documentation

rtcNewUserGeometry()

RTCORE_API unsigned rtcNewUserGeometry	(	RTCScene	scene,
		size_t	numGeometries
	)

Creates a new user geometry object. This feature makes it possible to add arbitrary types of geometry to the scene by providing appropiate bounding, intersect and occluded functions. A user geometry object is a set of user geometries. As the rtcIntersect and rtcOccluded functions support different ray packet sizes, the user also has to provide different versions of intersect and occluded function pointers for these packet sizes. However, the ray packet size of the called function pointer always matches the packet size of the originally invoked rtcIntersect and rtcOccluded functions. A user data pointer, that points to a user specified representation of the geometry, is passed to each intersect and occluded function invokation, as well as the index of the geometry of the set to intersect.

Parameters

scene	the scene the user geometry set is created in
numGeometries	the number of geometries contained in the set

rtcNewUserGeometry2()

RTCORE_API unsigned rtcNewUserGeometry2	(	RTCScene	scene,
		size_t	numGeometries,
		size_t	numTimeSteps = 1

Parameters

scene	the scene the user geometry set is created in
numGeometries	the number of geometries contained in the set
numTimeSteps	number of motion blur time steps

rtcSetBoundsFunction()

RTCORE_API void rtcSetBoundsFunction	(	RTCScene	scene,
		unsigned	geomID,
