Detailed Description

creates a closed mesh from a set of points.

This class only calculates the intersecting triangles of one cube, call multiple times for all points in the point cloud. Implements the algorithm in Lornsen1987:Marching Cubes

int BIAS::MarchingCubes::PolygoniseCube	(	MarchingCubesGridCell	grid,
		double	isolevel,
		MarchingCubesTriangle *	triangles
	)

Given a grid cell and an isolevel, calculate the triangular facets required to represent the isosurface through the cell.

Parameters

grid[in],:	the 8 grid cell corners which include coordinates and weights the weight of unoccupied corners should be 0, the weight if valid corners should be > 0 and > isolevel (parameter 2). The surface through the cube will be calculated according to these weights.
isolevel[in],:	isolevel of the cube
triangles[out],:	output triangles will be loaded up with the vertices at most 5 triangular facets.

Returns

the number of triangular facets 0 will be returned if the grid cell is either totally above of totally below the isolevel.
