2013-09-11BulletSim: fixes for change linkset implementation of physical linksets.Robert Adams4-17/+22
2013-08-27BulletSim: add some protections for processing when shutting down.Robert Adams1-2/+2
Attempt to fix Mantis 6740 (http://opensimulator.org/mantis/view.php?id=6740).
2013-08-20* Fix some threading issues in BulletXNA (the managed bullet library), this ↵teravus1-1/+45
should better allow you to run it in multiple region scenarios (but why would you really want to do that?) Source in OpenSimLibs. * Fixed a null ref during shutdown.
2013-08-14BulletSim: include check for volume detect in check for zeroing avatar motion.Robert Adams2-2/+6
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.
2013-08-14BulletSim: add physical object initialized flag so updates and collisionsRobert Adams5-5/+23
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.
2013-08-13BulletSim: move the creation of the avatar movement actor creating toRobert Adams1-7/+7
taint time. Attempt to fix a problem of teleporting within the same region where the remove and addition of the physical avatar occasionally ends up with a non-moving avatar.
2013-08-12BulletSim: add check in avatar stair step code to verify the collisionRobert Adams4-13/+26
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.
2013-08-08BulletSim: adjust avatar position when the avatar's size is changed.Robert Adams2-4/+12
This fixes the problem of avatars bouncing when logged in. Added a little height to the avatar height fudges to eliminate a problem of feet being in the ground a bit.
2013-08-02BulletSim: When converting linkset types, don't try to change the listRobert Adams1-9/+20
of linkset children while iterating through the list.
2013-08-02BulletSim: add implementation of 'physSetLinksetType' and 'physGetLinksetType'Robert Adams6-0/+95
and processing routines in BulletSim. Add linkset rebuild/conversion routine in BSLinkset.
2013-08-02BulletSim: add BSLinkInfo structure to remember link specific informationRobert Adams3-86/+174
for each link in a linkset. Extend BSLinksetConstraint to create and use BSLinkInfo with the default static constraint.
2013-07-30BulletSim: distribute vehicle physical settings to all members ofRobert Adams3-43/+61
a linkset. Enables constraint based linksets. Rename some internal variables to clarify whether values world or vehicle relative.
2013-07-30BulletSim: make density display and return value consistant with howRobert Adams3-8/+22
the simulator expects it (scaled to 100kg/m^3).
2013-07-23BulletSim: Turn on center-of-mass calculation by default.Robert Adams2-5/+7
Reduce object density by factor of 100 to bring physical mass computations into a range better suited for Bullet.

2013-07-22BulletSim: move collision processing for linksets from BSPrimLinkableRobert Adams5-18/+121
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.

2013-07-17BulletSim: fix small bug where everything looked like it was collidingRobert Adams2-6/+10
before the first simulator step.
2013-07-09BulletSim: add parameter to optionally disable vehicle linear deflection.Robert Adams2-16/+34
Add parameter to not apply vehicle linear deflection Z forces if vehicle is not colliding. This defaults to 'true' so vehicles will fall even if there is some linear deflection to apply.
2013-07-08BulletSim: make all the different angularVerticalAttraction algorithmsRobert Adams4-138/+146
selectable from configuration paramters. Changed default algorithm to "1" from previous default as it seems to handle Y axis correction a little better. Add config file independent enablement of vehicle angular forces to make debugging easier (independent testing of forces).
2013-07-07BulletSim: Different Implementation of Angular Deflection for vehicles, ↵Vegaslon1-15/+16
Activates it again and fixes problem with fighting with vertical attractor removing wobble of forward axis. Comments on testing welcome, May require adjustments of this force or other forces after this commit, exact tweaking to come after testing on other hardware.

2013-07-07BulletSim: fix jumping up and down of linksets when center-of-massRobert Adams1-6/+2
was enabled. Didn't effect the physical position but the viewer saw the linkset jumping between its simulator center and its physical center.

inconsistant use of Raw* and _* conventions.
2013-07-06BulletSim: implementation of linkset center-of-mass.Robert Adams5-29/+70
Default off, for the moment, until more testing. Add separate thread and center-of-mass flags to OpenSimDefaults.ini. Clean up comments in OpenSimDefaults.ini.
2013-07-06BulletSim: More tweaking on center-of-mass. Almost there. Changes have no ↵Robert Adams4-101/+51

2013-06-30BulletSim: set linkset type to be prim specific rather than a simulatorRobert Adams3-15/+8
wide default. This allows individual prims to differ in the underlying linkset implementation.
2013-06-30BulletSim: a better version of llMoveToTarget that doesn't go crazy.Robert Adams5-19/+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.

2013-06-20BulletSim: rework velocity updating when not colliding and not flyingRobert Adams2-5/+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.
