DMPolytopeGetVertexOrientation#

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 DMPolytopeGetVertexOrientation(DMPolytopeType ct, const PetscInt sourceCone[], const PetscInt targetCone[], PetscInt *ornt)

Not Collective

Input Parameters#

  • ct - The DMPolytopeType

  • sourceCone - The source arrangement of vertices

  • targetCone - The target arrangement of vertices

Output Parameter#

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

Note#

This function is the same as DMPolytopeMatchVertexOrientation() except it errors if not orientation is possible.

Developer Note#

It is unclear why this function needs to exist since one can simply call DMPolytopeMatchVertexOrientation() and error if none is found
