Hi, If you want to use the depth map to improve some rendering, I would recommend trying the multipass framework. You can have a look in the Example/Plugin/RenderPassViews directory in the sources, or you can have some higher level description at http://www.vtk.org/Wiki/VTK/MultiPass_Rendering

I was wondering how to achieve such a depthmap within paraview (from some 3D data such as a surface or a polygonal object). I guess such a filter does not exist right out of the box? Probably the elevation filter could be used for this, but I was wondering how I could get it to use the right axis (perpendicular to the screen from the camera position)? Thanks in advance for any hints.
