I have a complicated geometry with some really small (not very visible) self-intersecting faces to fix, like below:
I have tried to use the
shrinkwrap modifier and wrapped a fine-meshed cube on its surface. However, even though the cube is very finely meshed, the approximation is still not good:
I can use
remesh modifier to fix the self-intersecting faces, but it requires an astronomical amount of vertices (deep octree) to maintain the geometry.
Could anyone please help with some ideas? Thank you!
