Detailed Description

Helper class for creating entry and exit points for a mesh.

Member Function Documentation

operator()() [1/2]

void inviwo::algorithm::EntryExitPointsHelper::operator()	(	Image &	entryPoints,
		Image &	exitPoints,
		const Camera &	camera,
		const Mesh &	mesh,
		bool	capNearClip
	)

computes entry and exit points for raycasting using the given camera and bounding geometry mesh. The color components of mesh are interpreted as positions in Data space.

Parameters

entryPoints	entry points for raycasting the bounding geometry
exitPoints	exit points for raycasting the bounding geometry
camera	camera
mesh	mesh containing the bounding geometry, color must correspond to Data space
capNearClip	if true and the near clip plane of the camera is inside the volume, an additional plane will be used to close the volume in front of the camera

operator()() [2/2]

void inviwo::algorithm::EntryExitPointsHelper::operator()	(	Image &	entryPoints,
		Image &	exitPoints,
		const Camera &	camera,
		const Volume &	volume,
		const Mesh &	mesh,
		bool	capNearClip
	)

computes entry and exit points for raycasting using the given camera and bounding geometry mesh. Positions of mesh are mapped to Data space (texture coordinates) of the volume by using the Model to Data space transformation of volume.

Parameters

entryPoints	entry points for raycasting the bounding geometry
exitPoints	exit points for raycasting the bounding geometry
camera	camera
volume	used to determine the transformation of mesh positions to Data space
mesh	mesh containing the bounding geometry
capNearClip	if true and the near clip plane of the camera is inside the volume, an additional plane will be used to close the volume in front of the camera
