Hey.
I have an open source code library I'm working on where I wrote what I called an "omnitree" (and ND SPT). The goal was to use it to make a physics engine eventually, but when I showed it to a friend he showed me your library, and said it might help me get jump started. I agree.
To the question... Do you have any rules if I want to use your code to make my own version of your physics engine?
BTW... Here is my library... In case you are curious:
