 // TODOs for BulletSim (for BSScene, BSPrim, BSCharacter and BulletSim)
-// Test sculpties (verified that they don't work)
-// Compute physics FPS reasonably
 // Based on material, set density and friction
-// Don't use constraints in linksets of non-physical objects. Means having to move children manually.
-// Four states of prim: Physical, regular, phantom and selected. Are we modeling these correctly?
-//     In SL one can set both physical and phantom (gravity, does not effect others, makes collisions with ground)
-//     At the moment, physical and phantom causes object to drop through the terrain
-// Physical phantom objects and related typing (collision options )
-// Check out llVolumeDetect. Must do something for that.
-// Use collision masks for collision with terrain and phantom objects
 // More efficient memory usage when passing hull information from BSPrim to BulletSim
-// Should prim.link() and prim.delink() membership checking happen at taint time?
-// Mesh sharing. Use meshHash to tell if we already have a hull of that shape and only create once.
 // Do attachments need to be handled separately? Need collision events. Do not collide with VolumeDetect
 // Implement LockAngularMotion
-// Decide if clearing forces is the right thing to do when setting position (BulletSim::SetObjectTranslation)
-// Remove mesh and Hull stuff. Use mesh passed to bullet and use convexdecom from bullet.
 // Add PID movement operations. What does ScenePresence.MoveToTarget do?
 // Check terrain size. 128 or 127?
 // Raycast
