[Opensim-dev] PRIM_PHYSICS_SHAPE_TYPE and PRIM_PHYSICS_SHAPE_CONVEX missing.

[Adams, Robert]

BulletSim uses convex hulls for all physical objects. It does not use the convex hull that may have been defined in the mesh but it generates an approximate convex hull using the HACD algorithm (http://codesuppository.blogspot.com/2011/05/hacd-hierarchical-approximate-convex.html).

What do you require of the convex hulls?

standard opensim with ODE physics does not support convex hull collision shapes. I believe BulletSim does but I don't know if it's been extended into the LSL API.

The "Universal Hinged Motion in 8 Key Frames" is useing

 llSetLinkPrimitiveParamsFast(LINK_THIS,  [PRIM_PHYSICS_SHAPE_TYPE, PRIM_PHYSICS_SHAPE_CONVEX]);

It seems opensim dopnt support [PRIM_PHYSICS_SHAPE_TYPE, PRIM_PHYSICS_SHAPE_CONVEX] as setting ?
Time to dig my own example script up....
