When you think there are no connections any more do EDIT/SeparateShells. Hit X to discard this area and do the same select/discard around each hole: Hit G to expand that selection to groups: SELECT a ring around a hole connecting inside to the outside: Set a high SizeThreshold to get rid of small groups: The normals of outside and inside are nearly contrary. If there are connections you need to break them.Ī useful feature is to EDIT/GenerateFaceGroups based on surface NormalAngle mode. Please ignore that this human skull doesn't show a correct inside as you might have it from a CT(?) scan. If its an outside you need to flip the hole mesh (SelectAll+Edit/FlipNormals) I hope that makes somewhat sense, and if anyone has any ideas that could help me to do this I would greatly appreciate it.ĭid you already do some flipping? The stripe pattern indicates that it is a flipped surface (backfaces) pointing to the inside. What I want to do with my mesh is basically flip it inside out like that so I can have a 3D model of what would fill the inner cavity if there was something there. The ones that you had to flip inside out and then it pops in the air.
A good example of what I am trying to do is those little popper things you would get in birthday goody bags. Instead of my first idea, I thought it may be easier to just completely inverse the mesh. My first thought was to find a way to essentially create a virtual reverse mold, in that I wanted to make a virtual mold of the inner cavity, and then separate the virtual mold of the inner cavity from the mesh itself.
I am new to meshlab/meshmixer and have created a virtual mesh with fiji and have been tryong to edit it with meshlab and meshmixex but am unable to obtain my desired product.īasically I have a hollow mesh, and am interested in the inner cavity.
