Robert Adams 1b021e0eaa BulletSim: add ID parameter to TaintedObject calls so logging will include LocalID of object which created the taint. 2013-09-20 21:03:14 +01:00
Robert Adams e8b1e91a1d BulletSim: include check for volume detect in check for zeroing avatar motion.
Normally, avatar motion is zeroed if colliding with a stationary object so
they don't slide down hills and such. Without volume detect check this also
allowed avatars to stand on volume detect objects and to have some jiggling
when they were in the volume detect object. This commit fixes both.

Robert Adams 7c3b71d294 BulletSim: add physical object initialized flag so updates and collisions
don't happen until the object is completely initialized.

This fixes the problem of doing a teleport while the simulator is running.
The destruction of the physical object while the engine is running means
that the physics parameter update would overwrite the new position of the
newly created avatar.

Robert Adams 2c31fe4614 BulletSim: add check in avatar stair step code to verify the collision
is not with a volume detect object.

This fixes a problem of avatars trying to step over a volume detect object
that they collide with. This appeared as the avatar popping up as it started
to step up but then continuing on since the object wasn't physically interacting.

Robert Adams 5a7784a0e6 BulletSim: make density display and return value consistant with how

Robert Adams aec8852af7 Revert "Revert "BulletSim: move collision processing for linksets from BSPrimLinkable""
Found that the vehicle movement problem was not caused by these physics changes.

This reverts commit c45659863d.

Robert Adams c45659863d Revert "BulletSim: move collision processing for linksets from BSPrimLinkable"
The changes don't seem to be ready for prime time.

Robert Adams b4c3a791aa BulletSim: move collision processing for linksets from BSPrimLinkable
into the linkset implementation classes.
Add HasSomeCollision attribute that remembers of any component of
   a linkset has a collision.
Update vehicle code (BSDynamic) to use the HasSomeCollision in place of
   IsColliding to make constraint based linksets properly notice the ground.
Add linkset functions to change physical attributes of all the members
   of a linkset.

Robert Adams 23516717e4 BulletSim: a better version of llMoveToTarget that doesn't go crazy.
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.

Robert Adams e5582939fd BulletSim: massive refactor of shape classes. Removed shape specific code from BSShapeCollection. Using BSShape* classes to hold references to shape. Simplified shape dependency callbacks. Remove 'PreferredShape' methods and have each class specify shape type. Disable compound shape linkset for a later commit that will simplify linkset implementation. 2013-04-29 07:38:40 -07:00

Robert Adams 913965256f BulletSim: Adapt BulletSim to the newer physical properties. Viewer
dialog setting of friction, restitution, ... working.

on a moving object.
Rearrange pre/post action subscription code to put more in locks.

Robert Adams ddef8f16e5 BulletSim: first attempt at reporting top colliders 2013-01-27 12:50:05 -08:00
Robert Adams c44a8e9f92 BulletSim: finish the post step event for physical object actions. Modify vehicle to use post step event for logging. 2013-01-27 12:50:04 -08:00
Robert Adams 471c477863 BulletSim: allow changing position and rotation of a child of a linkset
without rebuilding the whole compound shape. Should make vehicles move
smoother.
2013-01-21 15:58:22 -08:00
Robert Adams c6b6c94ccb BulletSim: reduce jitter in avatar velocity when walking or flying.
OpenSimulator is VERY sensitive to changes in avatar velocity and
will send an avatar update message when velocity changes more than
0.001m/s. This significantly reduces the number of avatar update messages by
smoothing the avatar velocity returned by Bullet.
2013-01-18 11:39:24 -08:00
Robert Adams 75f710f1e7 BulletSim: Add one function that all actors who act on the physical
can use to know if the object is currently active.
Code cleaning including use of Util.ClampV function.
2013-01-17 14:47:35 -08:00
Robert Adams 4e1ca890c2 BulletSim: fix not moving physical objects below terrain to over terrain.
Add locking on register prestep action list preventing potential race conditions.
Little comment and formatting changes.
2013-01-14 15:46:46 -08:00
Robert Adams 459fcd81c9 BulletSim: move center of gravity of linkset to its geometric center.
Necessitated allowing simulator and physical position of a body to
get out of sync since Bullet assumes that <0,0,0> is the center of mass.
Update DLLs and SOs for the UpdateChildTransform so positions of
  individual prim in a linkset can be implemented.
2013-01-11 16:47:53 -08:00
Robert Adams 93adc4cb66 BulletSim: Add IsSelected attribute to physical objects. Have vehicles check to see if physical before trying to step. Replace vehicle gravity application. Previously relying on Bullet to apply gravity but since vehicles over-ride the velocity calculation, gravity never had a chance to accelerate the body down. Added AddForceImpulse as well as AddForce for those who need to apply immediate velocity updates. Use the impulse to apply the linear motion. 2013-01-11 16:47:20 -08:00
Robert Adams 8452c0a870 BulletSim: add function to push avatar up when hitting stairs.
It looks like BulletSim and ODE rely on penetration correction to cause
the avatar to move up and thus allowing walking up stairs. Object
penetration was minimized for walking and flying (so one doesn't go
through walls) and this stopped stairs from working. This commit
introduces avatar movement code to check for collisions at the
feet while walking and attempts to raise the avatar for the steps.
Not yet perfect but movement is better.

Robert Adams 92a6958b6d BulletSim: fix problem where pre-step actions would not replaced
by new registrations thus causing multiple instances of an action.

Robert Adams 9218748321 BulletSim: another round of conversion: dynamics world and collision object functions. 2012-12-31 19:57:22 -08:00
Robert Adams 203588e3c0 BulletSim: change physical data structures to classes. Add default
instantiations for PhysBody and PhysShape when BSPhysObject is created
to account for them being classes and not structures.
Update TODO list.
2012-12-31 19:57:21 -08:00
Robert Adams 7a5f598399 BulletSim: move logic for IsColliding, CollidingGround and CollidingObj from individual sub-classes and up to parent BSPhysObject class. 2012-12-27 22:12:27 -08:00
Robert Adams 80cee1b85a BulletSim: Fix single physical prim reporting its mass as zero.
Properly return root mass as mass of just the root prim rather
than the mass of the linkset. SOG has the logic to add the masses
together to get the linkset mass.
Update TODO list.
