static bool PCV::Launch	(	std::vector< CCVector3 > &	rays,
		cloudViewer::GenericCloud *	vertices,
		cloudViewer::GenericMesh *	mesh = `nullptr`,
		bool	meshIsClosed = `false`,
		unsigned	width = `1024`,

		cloudViewer::GenericProgressCallback *	progressCb = `nullptr`,
		QString	entityName = `QString()`
	)

static

Simulates global illumination on a cloud (or a mesh) with OpenGL.

Computes per-vertex illumination intensity as a scalar field.

Parameters

rays	light directions that will be used to compute global illumination
vertices	vertices (eventually corresponding to a mesh - see below) to englight
mesh	optional mesh structure associated to the vertices
meshIsClosed	if a mesh is passed as argument (see above), specifies if the mesh surface is closed (enables optimization)
width	width of the OpenGL context used to simulate illumination
height	height of the OpenGL context used to simulate illumination
progressCb	optional progress bar (optional)
entityName	entity name (optional)

static int PCV::Launch	(	unsigned	numberOfRays,
		cloudViewer::GenericCloud *	vertices,
		cloudViewer::GenericMesh *	mesh = `nullptr`,
		bool	meshIsClosed = `false`,
		bool	mode360 = `true`,
		unsigned	width = `1024`,
		unsigned	height = `1024`,
		cloudViewer::GenericProgressCallback *	progressCb = `nullptr`,
		QString	entityName = `QString()`
	)

static

Simulates global illumination on a cloud (or a mesh) with OpenGL - shortcut version Computes per-vertex illumination intensity as a scalar field.

Parameters

numberOfRays	(approxiamate) number of rays to generate
mode360	whether light rays should be generated on the half superior sphere (false) or the whole sphere (true)
vertices	vertices (eventually corresponding to a mesh - see below) to englight
mesh	optional mesh structure associated to the vertices
meshIsClosed	if a mesh is passed as argument (see above), specifies if the mesh surface is closed (enables optimization)
width	width of the OpenGL context used to simulate illumination
height	height of the OpenGL context used to simulate illumination
progressCb	optional progress bar (optional)
entityName	entity name (optional)

Returns: number of 'light' directions actually used (or a value <0 if an error occurred)
