I have tried that, it works for simple models but for complex models it takes more time and even crashes. There are threads with says VTK Boolean is not good for complex cases.
I am looking for something like create a distance map on the plane below and use vtkWrap filter to elevate and create the mesh. I cannot figure out how to get this distance map fast with good precision. Could we use ZBuffer ? it is hard to comprehend from the documentation and examples.
Thanks
