Detailed Description

Used to delete points that are connected to 4 triangles and then retriangulate the void.

Member Function Documentation

std::pair< int, int > xms::TrAutoFixFourTrianglePtsImpl::EdgeOppositePt	(	int	a_ptIdx,
		int	a_tri,
		VecInt &	a_tris
	)

Finds and removes the points connected to 4 triangles.

Parameters

Returns: a pair of ints that are the point indexes to the points on the edge opposite a_ptIdx

void xms::TrAutoFixFourTrianglePtsImpl::Fix ( BSHP< TrTin > a_tin )

overridevirtual

Removes any points in the tin that are connected to only 4 triangles. These points usually cause poorly formed elements in the mesher.

Parameters

[in,out] a_tin The tin to be modified.

void xms::TrAutoFixFourTrianglePtsImpl::MakeTwoNewTriangles	(	VecPt3d &	a_pts,
		std::map< int, int >	a_edges,
		int	a_tris[2][3]
	)

Makes 2 new triangles from the 4 edges passed into this method.

Parameters

[in]	a_pts	: Array of point locations in the TIN
[in]	a_edges	: A map of edges that surround the point that is being removed.
[out]	a_tris	: Array of point indexes that will define the new triangles
