Hey not sure if this is the right place to put this question.
I'm using Houdini to create a bunch of complex constraint relationships. I export the houdini constraint data as json and generate Obi constraint batches via a custom blueprint script.
This is all working pretty well but my Houdini configurations rely heavily upon Bend Constraints which in Houdini's vellum are implemented as two triangles sharing an edge; four points per constraint. (https://www.cs.ubc.ca/~rbridson/docs/cloth2003.pdf)
Obi's implementation of bending constraints, I believe uses this technique (http://image.diku.dk/kenny/download/kela...e.ea10.pdf) Which isn't going to give me the results I'm after.
I guess my questions are:
Was there a reason you chose the triangle blending constraint implementation vs the two triangle edge one?
Are there any plans to add support for the two triangle edge Bending constraint?
How difficult would it be to extend Obi to add support for this constraint? I'm assuming I would have to modify the Burst Solver.
