◆ AddFacet()

void MeshCore::MeshFacetGrid::AddFacet	(	const MeshGeomFacet &	rclFacet,
		ElementIndex	ulFacetIndex,
		float	fEpsilon = `0.0f`
	)

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.
