Member Function Documentation

Mesh * multipr.DecimationFilterGradAvg::apply	(	Mesh *	pMesh,
		const char *	pArgv,
		const char *	pNameNewMesh
	)			[virtual]

Creates a new Mesh by decimating the given Mesh with this DecimationFilter.

For each element Keep this element if all its points (related to a field) have a |gradient| > threshold.

For each point, gradient is computed by considering all the neighbours in a sphere of radius r.

Parameters:

	pMesh	any mesh to be decimated; must not be NULL.
	pArgv	all the arguments of the filter as a string; must not be NULL. for GradAvg, expected "fieldName fieldIt threshold radius boxing" (5 parameters).
	pNameNewMesh	name of the decimated mesh; must not be NULL.

Returns:

the decimated mesh.

Implements multipr.DecimationFilter.

med_float multipr.DecimationFilterGradAvg::computeNormGrad	(	const PointOfField &	pPt,
		const std::vector< PointOfField > &	pNeighbours
	)			const

Returns the norm of the gradient of the field at the given point.

Sub-method used by apply().

Parameters:

	pPt	any point in the field.
	pNeigbours	neighbourhood of pPt.

Returns:

the norm of the gradient of the field in pPt.
