* BulletSim: remove the handle to the vehicle actor and cause routinesRobert Adams2013-06-302-32/+70
| | | | that need it to look it up.
* BulletSim: set linkset type to be prim specific rather than a simulatorRobert Adams2013-06-303-15/+8
| | | | | wide default. This allows individual prims to differ in the underlying linkset implementation.
* BulletSim: a better version of llMoveToTarget that doesn't go crazy.Robert Adams2013-06-305-19/+98
| | | | | | | | There is still some overshoot but mostly fixes Mantis 6693. Fix bug where moveToTarget was active for non-physical objects and while selected. Fix bug where move target was not getting changed if the script changed the target during a move.

| | | | | | vehicle tuning diffrence between Opensim and Second life. Signed-off-by: Robert Adams <Robert.Adams@intel.com>
* BulletSim: rework velocity updating when not colliding and not flyingRobert Adams2013-06-202-5/+42
| | | | | | | to prevent infinite jumps. Now jumps last only AvatarJumpFrames long (default 4) which is about as high as in SL. TODO: jumping should only depend on standing (collision with feet) rather than collision anywhere on the avatar.
* BulletSim: when meshing or asset fetching fails, include positionRobert Adams2013-06-112-14/+30
| | | | and region with the offending object's name in the error message.
* BulletSim: add failure flag for meshing failure vs asset fetch failureRobert Adams2013-06-104-34/+51
| | | | | | so error messages make more sense. Change some BulletSim status log messages from WARN to INFO. Update TODO list.
* BulletSim: default PhysicsTimeStep to same as the simulator'sRobert Adams2013-06-051-1/+1
| | | | | | heartbeat timestep when running the physics engine on a separate thread. This reduces the occurance of heartbeats that happen when there is no physics step which is seen as vehicle jerkyness.
* BulletSim: fix corner case when rebuilding a compound linkset whileRobert Adams2013-06-051-11/+46
| | | | | | a mesh/hull while a mesh or hull is being rebuilt when its asset is fetched. This fixes a 'pure virtual function' crash when changing physical state of complex linksets that include many meshes.
* BulletSim: experimental movement of physics execution off of heartbeatRobert Adams2013-06-013-73/+209
| | | | | | | | | | thread. Off by default until more testing. Setting "[BulletSim]UseSeparatePhysicsThread=true" causes the physics engine to be called on its own thread and the heartbeat thread only handles the reporting of property updates and collisions. Physics frame rate is about right but physics execution time goes to zero as accounted by the heartbeat loop.
* BulletSim: don't zero motion when changing vehicle type.Robert Adams2013-05-281-1/+4
| | | | | Some vehicle scripts change type on the fly as an easy way of setting all the parameters (like a plane changing to a car when on the ground).
* BulletSim: default using mesh asset hulls to 'true'. This means that,Robert Adams2013-05-271-2/+2
| | | | | | if the mesh asset specifies physics hulls, BulletSim will fetch and use same rather than approximating the hulls. If physics hulls are not specified, the representation will fall back to the regular physics mesh.
* BulletSim: enable GImpact shape for prims with cuts. Include DLLs and SOsRobert Adams2013-05-261-1/+1
| | | | | | | | | | | which recompute GImpact shape bounding box after creation as Bullet doesn't do that itself (something it does for nearly every other shape). Now, physical prims without cuts become single mesh convex meshes. Physical prims with cuts become GImpact meshes. Meshes become a set of convex hulls approximated from the mesh unless the hulls are specified in the mesh asset data. The use of GImpact shapes should make some mechanical physics more stable.
* Meshmerizer: remember to add the copied hull verts to the list of hulls.Robert Adams2013-05-241-0/+1

* BulletSim: add VehicleInertiaFactor to allow modifying inertia.Robert Adams2013-05-242-1/+5
| | | | | Another parameter for vehicle operation tuning. Default to <1,1,1> which means nothing is different under normal use.
* BulletSim: properly set mesh hash key in use tracking structure.Robert Adams2013-05-241-1/+4
| | | | Shouldn't see any functional difference.
* Meshmerizer: add INI parameter to enable DEBUG mesh detail logging.Robert Adams2013-05-241-3/+6
| | | | | | | | Default to off. To turn mesh parsing DEBUG detail logging on, add [Mesh] LogMeshDetail=true to the INI file.

* Revert "BulletSim: add code to experimentally use asset hull data."Robert Adams2013-05-212-54/+4
| | | | | | | | This reverts commit 2fd8819a043269f9308cb46c71893e6eb35a426e. Remove this code until I can figure out why the references that are clearly in prebuild.xml doesn't work for the 'using OpenSim.Region.Physics.Meshing' in BSShape.cs.
