Is it possible to get the ZMap from the Point cloud data?

Hi all.
I have a question about the ZMap and the Point cloud data.

Because the Point cloud is in mm, there is no distortion in the image, even if the X and Y resolution are different.
However, the ZMap in pixels has a different ratio of X and Y resolution, which results in distortion of the ZMap image.

Is there any way to get an mm ZMap from the Point cloud using VTK?

Thank you :slight_smile:

Best regards,
