DMPolytopeMatchVertexOrientation#

Determine an orientation (transformation) that takes the source vertex arrangement to the target vertex arrangement

Synopsis#

#include "petscdm.h"          
#include "petscdmlabel.h"     
#include "petscds.h"     
PetscErrorCode DMPolytopeMatchVertexOrientation(DMPolytopeType ct, const PetscInt sourceVert[], const PetscInt targetVert[], PetscInt *ornt, PetscBool *found)

Not Collective

Input Parameters#

  • ct - The DMPolytopeType

  • sourceVert - The source arrangement of vertices

  • targetVert - The target arrangement of vertices

Output Parameters#

  • ornt - The orientation (transformation) which will take the source arrangement to the target arrangement

  • found - Flag indicating that a suitable orientation was found

Note#

An arrangement is a vertex order

Each orientation (transformation) is labeled with an integer from negative DMPolytopeTypeGetNumArrangments(ct)/2 to DMPolytopeTypeGetNumArrangments(ct)/2 that labels each arrangement (vertex ordering).

See DMPolytopeMatchOrientation() to find a new face orientation that takes the source face arrangement to the target face arrangement
