Virtual tissue cutting in real-time medical simulations

[korzen]

Hello @loopstring ,

first of all, big thanks for sharing this code! Great work - mesh cutting is a super challenging topic and, beside tetcutter, I am not aware of any other open code in this field. May I ask if you are the author behind the Adaptive Virtual Node paper? If yes then I would like to congratulate on your work!

I have smoothly integrated your code with my Position Based Dynamics simulation framework in Unity3D and run some initial test. https://cdn.pbrd.co/images/H8e6mfy.jpg

So far so good. However, there is still a long way before apply this method in simulation.

For example, any general suggestions on how to tackle the gradual cutting, e. g. when scalpel is going through the tissue?

Currently, it seems that there is no snapping or resulting structures optimizations. Also the edges of cutting mesh generate new nodes on the cutted mesh.

In other words, what are the plans for further developments? Are you interested only in the cutting algorithm alone or you'd like to push it further towards complete out-of-the-box solution

Thank you
