void Triangle::MarkEdge	(	const DSTable &	v_to_v,

References indices.

void Triangle::MarkEdge

(

DenseMatrix &

pmat

)

[virtual]

Reorder the vertices so that the longest edge is from vertex 0 to vertex 0. If called it should be once from the mesh constructor, becouse the order may be used later for setting the edges.

Reimplemented from Element.

Definition at line 49 of file triangle.cpp.

References indices.

int Triangle::NeedRefinement	(	DSTable &	v_to_v,
		int *	middle
	)		const [virtual]

Return 1 if the element needs refinement in order to get conforming mesh.
