_WlzGMVertexG3N Struct Reference
WlzGeoModel

The position of a point in 3D double precision space and the normal vector at that point. Note that the data structure is the same as WlzGMVertexG3D until the normal, this is important as it allows the type, index and position to be established without knowing whether the vertex geometry is WlzGMVertexG3D or WlzGMVertexG3N. Typedef: WlzGMVertexG3N. More...
