Member Function Documentation

void VolGridEllipticalMarchingCubes::build (  float  isovalue  )

This method is called to run the Elliptical Marching Cubes algorithm. Parameters: isovalue  defines the level to extract the surface from.

void VolGridEllipticalMarchingCubes::generateSurface (   )

This method is called to generate the surfels.

bool VolGridEllipticalMarchingCubes::iterate (  OcTreeTraversalNode *  travNode  )  [virtual]

Needed to iterate the octree. Reimplemented from OcTreeIterator.

void VolGridEllipticalMarchingCubes::marchingCubes (  float  values[8], float  level, int &  nVertices, int  edgeStart[12], int  edgeEnd[12], float  param[12], int &  nTriangles, int  triangles[5][3] )

This method determines the triangle positions of a volumetric grid cell according to the modified Marching Cubes algorithm. Parameters: values[8]  the distance values from the eight corners of the cube. level  defines the iso-level to extract from (normally level = 0.0) nVertices[8]  defines the number of vertices according to the Marching Cubes look-up table. edgeStart[12]  defines on which edge the corresponding edge start is according to the Marching Cubes look-up table. edgeEnd[12]  defines on which edge the corresponding edge end is according to the Marching Cubes look-up table. param[12]  defines the where the point has to be located [0,1] on an edge. nTriangles  number of triangles according to the Marching Cubes look-up table. triangles[5][3]  triangles according to the Marching Cubes look-up table.
