Member Function Documentation

void MeshCore::MeshFacetGrid::AddFacet	(	const MeshGeomFacet &	rclFacet,
		unsigned long	ulFacetIndex,
		float	fEpsilon = `0.0f`
	)			`[inline, protected]`

Adds a new facet element to the grid structure.

rclFacet is the geometric facet and ulFacetIndex the corresponding index in the mesh kernel. The facet is added to each grid element that intersects the facet.
