- revert a critical change form "Mesh_Particles_Json" merge 6a0357c - revert a dT Force patch calc optimization to be improved later on
- kT improved with addional precalc kernel to reduce calculating some data twice - dT improved by simplyfing force calculation and added some earlier exits
- a simple/fast plane contact but in cylindric direction
- Done by requiring tri--tri primitive contacts to respect the general relative direction of the mesh patches involved to have the right in contact normal voting. So this is still done by finding a good voting strategy which I believe is the key to rule out remote fake contacts
- Added also a tri path for different tangential stiffness
- tri edge neighbors for contact islands - finer contact mesh is "winner" and defines the islands - convace demo change (cross.stl) to check function
- clean up mesh splitting section inculding test - added full fast path for convex shape that never win (contact island always more coarse on their side) - SimpleCollision demo expanded
