Static Public Member Functions | |
template<class RayOutputIterator, class FaceOutputIterator> | |
static void | createNonNegativeCone (NTriangulation *triangulation, RayOutputIterator rays, FaceOutputIterator faces) |
Writes to the given output iterators newly allocated rays and faces representing the cone obtained by setting all coordinates non-negative in the flavour of coordinate system corresponding to this particular subclass of NNormalSurfaceVector. | |
static NMatrixInt * | makeMatchingEquations (NTriangulation *triangulation) |
Creates a new set of normal surface matching equations for the given triangulation using the flavour of coordinate system corresponding to this particular subclass of NNormalSurfaceVector. | |
static NCompConstraintSet * | makeEmbeddedConstraints (NTriangulation *triangulation) |
Creates a new set of compatibility constraints representing the condition that normal surfaces be embedded. |
If there are t tetrahedra in the underlying triangulation, there must be precisely 7t coordinates. The first seven coordinates will be for the first tetrahedron, the next seven for the second tetrahedron and so on. For each tetrahedron, the first four represent the number of triangular discs about vertex 0, 1, 2 and 3, and the next three represent the number of quadrilateral discs of type 0, 1 and 2 (see NNormalSurface::getQuadCoord()).

Determines if the specific underlying coordinate system allows for almost normal surfaces, that is, allows for octahedral discs. Note that this has nothing to do with whether or not this specific surface contains octahedral discs.
