Member Function Documentation

bool chrono::ChConvexDecomposition::AddTriangle ( const ChTriangle & t1 )

virtual

Add a triangle, by passing a ChTriangle object (that will be copied, not referenced).

Note: the vertices must have proper winding (oriented triangle, normal pointing outside).

virtual bool chrono::ChConvexDecomposition::AddTriangle	(	const ChVector3d &	v1,
		const ChVector3d &	v2,
		const ChVector3d &	v3
	)

pure virtual

Add a triangle, by passing three points for vertices (that will be copied, not referenced).

Note: the vertices must have proper winding (oriented triangle, normal pointing outside).

bool chrono::ChConvexDecomposition::AddTriangleMesh ( const ChTriangleMesh & tm )

virtual

Add a triangle mesh, by passing an entire ChTriangleMesh object.

Note: the triangles must define closed volumes (holes, gaps in edges, etc. may trouble the decomposition).
