# DMPlexTransformGetTargetPoint
Get the number of a point in the transformed mesh based on information from the original mesh. 
## Synopsis
```
#include "petscdmplextransform.h" 
PetscErrorCode DMPlexTransformGetTargetPoint(DMPlexTransform tr, DMPolytopeType ct, DMPolytopeType ctNew, PetscInt p, PetscInt r, PetscInt *pNew)
```
Not Collective


## Input Parameters

- ***tr    -*** The `DMPlexTransform`
- ***ct    -*** The type of the original point which produces the new point
- ***ctNew -*** The type of the new point
- ***p     -*** The original point which produces the new point
- ***r     -*** The replica number of the new point, meaning it is the rth point of type `ctNew` produced from `p`



## Output Parameter

- ***pNew  -*** The new point number
