Hi, I am building a tree structure with some branches. Here you can see a screenshot of one tree example with only one branch:
I want to limit or constraint the (angles) movements of the linked segments of the full branch. I have a particle system with points on any junction/join. I want to use this boxes just as “flexible” bones; only for that function. One way could be to use the boxes with joints; something this:
EDIT: But I am not sure if it’s a good way, and maybe it should work easier with a spring/joint between balls; a ball on each join. I don’t know if in bullet joints can’t work like springs… or if it’s possible to limit the movents without using the boxes around each branch segment.
There’s a very nice project made by Rui Madeira, very similiar but in 2D: https://vimeo.com/4789754
each branch is made of particles connected with springs, using a Verlet integration (there is a lot of information about this, and several add ons for verlet physics). The motion is then creating by applying forces to the particles. For the wind i’m creating forces using perlin noise.
So, searching around I found some similar stuff like:
Here you can see some types of joints:
And here you can see the antenna of this tank too, where each segment has a perpendicular joint:
As you can see I am very lost…
