_WlzMeshElem3D Struct Reference
WlzTransform

Defines an tetrahedral mesh element within a mesh transform. The nodes and neighbours are indexed such that: Neighbour 0 shares surface ( nodes 0, 1 and 2), neighbour 1 shares surface (nodes 1, 3 and 2), neighbour 2 shares surface (nodes 2, 3 and 0 ) and neighbour 3 shares surface (nodes 0, 3 and 1 ) All the nodes stored in the following sequence: 0-1-2 formed a counter clockwise (CCW) order using the dircection of a surface outwards from the tetrahedron. 0-2-3 are also stored in counter clockwise (CCW) order. added by J. Rao 10/09/2001. More...
