* 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: add locking of PhysObjects while processing simulationRobert Adams2014-05-261-14/+20
| | | | | step updates and collisions. This is an attempt to fix a crash reported by Justin when doing high velocity teleports.
* BulletSim: adjust avatar step up parameters to better walk up smallRobert Adams2014-05-172-4/+4
| | | | | staircases. This change is required because of the change in the avatar default shape from the capsule to the rectangle.

| | | | | | | parameter 'TerrainGroundPlane' which defaults to -500. BulletSim had assumed altitudes never went negative but that is not true. The ground plane is just a safety net so things wouldn't fall to infinity.

* BulletSim: reduce the terrain collison margin to be the same as otherRobert Adams2014-04-121-1/+1
| | | | | | | | objects in the world. This was originally changed in an attempt to make vehicles work better but the effect was not that large and it causes avatars to float above the terrain.
* BulletSim: small tweek to avatar height reduce feet embedded into prims.Robert Adams2014-04-101-1/+1
| | | | | This adjustment makes a default, shoeless avatar stand properly on a prim for the various heights (0% to 100% in the appearance adjustment).

* BulletSim: make avatar physical shape to be a rectangle rather thanRobert Adams2014-04-023-11/+47
| | | | | | | | a capsule. Set the default to be the rectangle shape and adjust the parameters in OpenSimDefaults.ini for the new shape. The rectangle shape will perform better and avatar height can be computed more accurately.
* BulletSim: fix problem where axis constraints were also constrainingRobert Adams2014-03-231-3/+5
| | | | | | | linear motion. The code was limiting linear motion to be only in the positive direction for any axis that was constrained.

* BulletSim: the minimum vehicle velocity was set too low so moving slowRobert Adams2014-02-112-1/+12

* 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.

* BulletSim: implement the SL bug where VEHICLE_HOVER_UP_ONLY disablesRobert Adams2013-10-151-0/+12
| | | | | | | | | | | the vehicle buoyancy if the vehicle is above its hover height. This is a known misfeature of this vehicle flag which has been accepted since it would break too many implementations. The problem is noticed when creating a jetski-like vehicle that jumps over sand bars. A boat normally is configured with neutral buoyancy and hovering at water height. When it jumps the sandbar, it needs to have gravity applied to get back to water level.
