* BulletSim: add the beginnings of hull creation unit testing.Robert Adams2014-12-315-12/+394
| | | | | | Change how physics engine is created in unit tests to resolve a lib reference problem. Add ShapeInfoInfo class to collect info about the created physical shape for debugging and unit test testing.
* BulletSim: Add axis locking enabled through the ExtendedPhysics module.Robert Adams2014-12-314-69/+404
| | | | | Allows locking of prim/linkset relative moving in each of the linear and angular axis. Limits on movement or rotation can be set.

| | | | | | calling ZeroMotion in SetPhysicalProperties() at all SetPhysicalProperties is only called when adding a new character so it looks like there is no existing data to reset anyway.

* Somewhat improve avatar region crossings by properly preserving velocity ↵Justin Clark-Casey (justincc)2014-11-294-14/+40
| | | | | | | | | when avatar enters the new region. This commit addresses the following issues were causing velocity to be set to 0 on the new region, disrupting flight in particular * Full avatar updates contained no velocity information, which does appear to have some effect in testing. * BulletSim was always setting the velocity to 0 for the new BSCharacter. Now, physics engines take a velocity parameter when setting up characters so we can avoid this. This patch applies to both Bullet and ODE.
* refactor: Move methods to start a monitored thread, start work in its own ↵Justin Clark-Casey (justincc)2014-11-251-1/+1
| | | | | | | | thread and run work in the jobengine from Watchdog to a WorkManager class. This is to achieve a clean separation of concerns - the watchdog is an inappropriate place for work management. Also adds a WorkManager.RunInThreadPool() class which feeds through to Util.FireAndForget. Also switches around the name and obj arguments to the new RunInThread() and RunJob() methods so that the callback obj comes after the callback as seen in the SDK and elsewhere
* Add [BulletSim] option AvatarToAvatarCollisionsByDefault to control whether ↵Justin Clark-Casey (justincc)2014-11-253-3/+16
| | | | | | | | | avatars collide. This is true by default. This is implemented with a new collision type (PhantomToOthersAvatar) to potentially allow colliding and non-colliding avatars to be present in the same scene. So there is no provision yet for giving avatars different collision types. This commit replaces the temporary change in commit f3eaa6d8 where avatars would never collide when using BulletSim This is equivalent to the av_av_collisions_off option in ODE.
* If Bullet is running on its own thread, use a reset event to control timing ↵Justin Clark-Casey (justincc)2014-11-251-2/+9
| | | | | | | rather than a sleep. In theory, there should be no difference between these mechanisms. However, on at least Mono 3.2.8 waiting via an event appears to be much more accurate.

* Temporary hack to disable av to av collisions in bulletsim.Justin Clark-Casey (justincc)2014-11-251-1/+1

* If calling llStopMoveToTarget() on an in-world prim, don't send an ↵Justin Clark-Casey2014-11-193-7/+20

* BulletSim: fix exceptions while rebuilding linksets with mesh children.Robert Adams2014-06-081-3/+30
| | | | | | | This should get around the exception reported in Mantis 7191 and 7204 by checking for the unbuilt child and rebuilding the linkset the next tick. A warning message is output when this rebuild happens and this message is clamped to 10 times in case there is a problem with a loop.
* Fix issue with BulletSim avatar level flight jitter by commenting out ↵Justin Clark-Casey (justincc)2014-05-301-1/+12
| | | | | | | | | | | | RawVelocity update threshold for now in BSCharacter.UpdateProperties(). For some reason as yet unidentified (feedback?) a threshold above 0.4 here causes the RawVelocity to move between a lower and upper bound rather than remaining constant. The RawVelocity increased until it triggered the threshold update, at which point it started to decrease until it again triggered the threshhold update. This delta-v was enough to exceed the checks in ScenePresence.SendTerseUpdateToAllClients() and produce jittery avatar flight because of the fluctuating velocity. With a threshold of 0.4 (or 0, as with ODE), the RawVelocity remains constant in BulletSim and so avatar flight becomes mostly smooth - remaining occasional glitches appear to be a result of errors in distance extraploation. There are no obvious problems with commenting out the threshold. Misterblue, if this is wrong or I've missed some subtlety here, please feel free to revert and/or correct. The same considerations may or may not apply to object velocity updates.

* BulletSim: small tweek to avatar height reduce feet embedded into prims.Robert Adams2014-04-101-1/+1

* BulletSim: default physical terrain implementation to heightmap.Robert Adams2014-01-292-1/+9
| | | | | | | | It originally looked like mesh terrain would perform better for vehicles but, after much use, heightmap is the clear winner. Force terrain implementation to heightmap if the physics region is larger than legacy region size. This solves running out of memory for very large regions.
