Is there an easy way to switch the array used for the texture coordinates to different point scalar arrays present in a dataset?

I have three sets of texture coordinates as scalar arrays on my `vtkPolyData` surface and I have three corresponding texture images. I’d like a simple way to switch between the active texture coordinates and texture images.

There is no filter or mechanism to do this. **Programmable Filter** is your friend here. Say you want to switch to a texture named “DifferentTexture”. Then your script would look like

```python
input = self.GetInput()
output = self.GetOutput()
output.ShallowCopy(input)
output.GetPointData().SetActiveTCoords('DifferentTexture')

```
