Hi everyone, I am trying to find an automated way to clean up some CAD geometry that I have. Retopo is no problem, the only issue I have is that the model has a lot of interior geometry that I want to get rid of. Interior and extrerior are connected !!! So I was trying different things without getting a decent result. I am thinking that one should send out a ray along the normal and see what it hits. Ideally multiple rays at varied angles to be sure. Outside points should hit pretty much nothing. So how do I do that? I dont know if a gather loop is a good option. Anyway, I could bot get that to work on sop level. Any help with this would be truly great. Thank you very much in advance.
Hi there. I´ve been researching a bit on 3d scanning/photogrammetry lately, and was wondering about the following issue: Supposing I scan several different expressions for an actor, it´s clear to me how to retopologize one head to make a useable default mesh with displacements...now, how would one go about using other expressions? Blendshapes need same number of points, so I´m not quite clear about it. I´m not sure how could I create different displacement maps consdering the base mesh for each expression would be different. Any ideas on how this is done on production currently?
