I'm investigating algorithms to make a mesh watertight for 3d printing. I'd be very excited to implement such algorithms. The initial input is a mesh which is not watertight and I want to understand and implement algorithms to transform it to make it suitable for 3d printing.
Here is a good explanation about watertight meshes: http://support.ponoko.com/entries/20217167-creating-watertight-meshes-for-3d-printing
I've heard that the key to watertight meshes is shrink wrapping. I'm completely new to meshes.
- What are the most common shrink wrapping algorithms?
- Where can I find open source implementations?
- Where can I find real world inputs?
