I'm having problems with OCC interactive 3D views in Hidden Line mode.
I attached to this emal 2 links to 2 images: one is the an OCC sample and the other one is a test I'm developing to evaluate OCC.
In the first case, the OCC sample, the hidden line of each object works just fine, however is not working for the 3 objects aligned in the same 3D view.
In the second case I fuse 3 boxes and the hidden line does not work for all faces of the same shape.
Based on your experience should I look for a different graphics library, to put on top of OCC modeling kernel or OCC interactive graphics should work and is worth digging into the issue until resolution.
I really appreciate any comment.
