```auto
grid = rgb_to_vtk(np.ascontiguousarray(rgb))
texture = vtk.vtkTexture()
texture.SetInputDataObject(grid)

if interp:
    texture.InterpolateOn()

actor_obj.SetTexture(texture)

```

I did this converted rgb image to vtk image data -\> Created a texture with it and set it to the actor which removes the original texture and sets the new texture. Is there a way to update the old texture?

Thanks for help.
