DMPlexRestoreOrientedCone#

Restore the points and orientations on the in-edges for this point in the DAG

Synopsis#

#include "petscdmplex.h"   
PetscErrorCode DMPlexRestoreOrientedCone(DM dm, PetscInt p, const PetscInt *cone[], const PetscInt *ornt[])

Not Collective

Input Parameters#

  • dm - The DMPlex

  • p - The point, which must lie in the chart set with DMPlexSetChart()

  • cone - An array of points which are on the in-edges for point p

  • ornt - An array of orientations which are on the in-edges for point p. An orientation is an integer giving the prescription for cone traversal.

Notes#

The number indexes the symmetry transformations for the cell type (see manual). Orientation 0 is always the identity transformation. Negative orientation indicates reflection so that -(o+1) is the reflection of o, however it is not necessarily the inverse. To get the inverse, use DMPolytopeTypeComposeOrientationInv() with the identity.

Fortran Notes#

You must also call DMPlexRestoreCone() after you finish using the returned array. DMPlexRestoreCone() is not needed/available in C.
