DMPolytopeMatchOrientation#
Determine an orientation (transformation) that takes the source face arrangement to the target face arrangement

PetscErrorCode DMPolytopeMatchOrientation(DMPolytopeType ct, const PetscInt sourceCone[], const PetscInt targetCone[], PetscInt *ornt, PetscBool *found)
Not Collective
Input Parameters#
- ct - The - DMPolytopeType
- sourceCone - The source arrangement of faces 
- targetCone - The target arrangement of faces 
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 face order combined with an orientation for each face
Each orientation (transformation) is labeled with an integer from negative DMPolytopeTypeGetNumArrangements(ct)/2 to DMPolytopeTypeGetNumArrangements(ct)/2
that labels each arrangement (face ordering plus orientation for each face).
See DMPolytopeMatchVertexOrientation() to find a new vertex orientation that takes the source vertex arrangement to the target vertex arrangement
