This brush has a simple physics solver that helps when sculpting cloth
(which is one of the hardest things to do in any sculpting software).
The mass and the damping of the simulation properties of the brush.
It has 4 deformation modes that control how the forces are created.
The brush can create the constraints only on the required PBVH nodes, so
it should be easy to isolate the simulation on high poly meshes. As long
as the brush size is not too big it should be possible to keep it real
- The way constraints are created is extremely basic and it creates repeated constraints. Maybe there is another way to create fewer constraints while keeping the simulation quality decent. This part can also be multithreaded. (As it is it works ok, but it could be better)
