Automatically draw hidden portions of paths with dashed lines This is a follow up to a question of mine on TeX stackexchange site.



Is it possible in blender to have an open surface that would render as opaque but the render would show automatically, depending on the position of the camera, the hidden parts of its boundary with dashed lines?

I'm a beginner in blender. Here is a simple blend file reproducing the surface of my original post.
Can do this using Freestyle and choose how to render Hidden edges. The zipped sample file renders the image below.



Select dashed line style from the Freestyle Line Style Panel in Render Layers Properties.
