1410: DMPlexTransformCellTransformIdentity - Default `celltransform` implementation for transforms that reproduce the input mesh
1412: Not Collective
1414: Input Parameters:
1415: + tr - The `DMPlexTransform`
1416: . source - The cell type of the source point
1417: - p - The source point
1419: Output Parameters:
1420: + rt - Refinement type of the source point (set to 0), or `NULL`
1421: . Nt - Number of target cell types produced (always 1)
1422: . target - Array of produced cell types (a single-element array containing `source`)
1423: . size - Array of replica counts for each produced type (a single-element array containing 1)
1424: . cone - Cone description used by `DMPlexTransformGetCone()`; encodes that the replica takes the entire parent cone
1425: - ornt - Orientation array associated with `cone`; all zero for identity
1427: Level: developer
1429: Note:
1430: This routine returns statically allocated arrays describing an identity refinement for each supported
1431: `DMPolytopeType`; every source point produces a single replica of the same type with unchanged cone
1432: and orientation.
