angle constraints #3

Open forresto opened 7 years ago

forresto commented 7 years ago

Would it be possible to make a new lib (like verlet-constraint) for angle constraints?

Subprotocol's version: https://github.com/subprotocol/verlet-js/blob/3293d409aafe3adfd56811849b9168cb84599c28/lib/constraint.js#L76-L99

In case anybody is looking at my work in that repo ☝️ , the angle constraints need some help: they don't respect mass and stiffness correctly yet. Anybody want to help me with that math?

Setting the angle constraints based on base shape in frame 0, you see distance constraints take effect in frame 1, then the angles work it out: tshirt-slider-solve
