Function Documentation

GEOMLIBEXPORT int Delaunay3D	(	DPOINT3D **	Nodes,
		TRIANGLEREF **	Triangles,
		INT32 *	NumNodes,
		INT32 *	NumTriangles,
		double	Tolerance
	)

Performs Delaunay triangulation (short parameters list).

Note: This function calls DelaunayProc.

Parameters:

	Nodes	Input/output array of points
	Triangles	Output array of triangles
	NumNodes	Number of input/output nodes passed/returned
	NumTriangles	Number of the output triangles
	Tolerance	Spatial tolerance

GEOMLIBEXPORT int DelaunayProc	(	DPOINT3D **	Nodes,
		TRIANGLEREF **	Triangles,
		RVCTINHULLEDGE **	Con,
		RVCTINHULL *	HullInfo,
		INT32 *	NumNodes,
		INT32 *	NumTriangles,
		INT32 *	NumHullEdges,
		double	Tolerance
	)

Performs Delaunay triangulation (full parameters list).

NOTE: The triangle vertices in TRIANGLEREF structure are organized in clockwise direction (when looking down) WARNING: The order of input Nodes will be changed, all nodes will be sorted using X coordinate (then Y if two points have equal X coordinates). WARNING: NUMBER OF NODES RETURNED MIGHT BE DIFFERENT FROM INPUT, because of duplicate point removal using tolerance value.

Parameters:

	Nodes	Input/output array of points
	Triangles	Output array of triangles
	Con	Output array of hull edges
	HullInfo	Information about convex hull
	NumNodes	Number of input/output nodes passed/returned
	NumTriangles	Number of the output triangles
	NumHullEdges	Number of the hull edges
	Tolerance	Spatial tolerance
