Points constraint approach Hello, I'd like some suggestions and pointers about what approach I could take for this specific matter. I basically have a line made of n points (well, a hair): when I move one or more points, I need the other points to be constrained so that the hair length remains the same. I'm currently using verlet integration which works just fine: the only issue is that requires a 2nd step, so first, the points are moved to "unconstrained" positions; after that, the verlet integrations moves them back to the correct positions so that are constrained (and hair length remains the same). So I was wondering, there is an approach that would require 1 single step? Perhaps I could achieve the same behavior with Euler or quaternions? Thanks for any suggestion! https://ift.tt/eA8V8J
