Hi!

I've got 2 curves representing a trunk and a branch. I'm using a vellumHair and a vellum Solver. When I press play, it all falls down. Fantastic!

...Now, I'd like the branch curve to be attached to the trunk curve. How do I do that? Is there a specific node for that? Can I do it in vex?

I've never worked with constraint so I'm a bit clueless.

You can fuse the points in a variety of ways. A simple fuse by distance will get you started.

If you are doing what I think you are doing bare in mind to get a more stable solve you should use as few points as possible to the extreme...

My goal was to not fuse the branch to the trunk. The spacing makes sens since the trunk has thickness. Isn't there a way I can simply make a constraint that "links" the bottom of the branch to the trunk?

I tried using a vellumConstraint set to Glue. The branch is attached to the trunk but moves like a pendulum (it doesnt keep it's initial position/angle).

Since I love vex, I wish I could learn how to create those constraints myself.

This is a simple example file, hope it helps.
