2014-05-30Fix issue with BulletSim avatar level flight jitter by commenting out ↵Justin Clark-Casey (justincc)1-1/+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.
2014-05-26BulletSim: add locking of PhysObjects while processing simulationRobert Adams1-14/+20
step updates and collisions. This is an attempt to fix a crash reported by Justin when doing high velocity teleports.

to west.
2014-05-17BulletSim: adjust avatar step up parameters to better walk up smallRobert Adams2-4/+4
staircases. This change is required because of the change in the avatar default shape from the capsule to the rectangle.
2014-04-29Add regression test for NPC movement on a variable region.Justin Clark-Casey (justincc)1-5/+12
Extends basic physics to allow av movement on a varregion (basic physics is only really useful for regression test purposes).
2014-04-28BulletSim: non-functional changes to debugging statements and formatting.Robert Adams1-6/+6
2014-04-28BUlletSim: move safeynet ground plane to lower altitude. Define new BulletSimRobert Adams2-2/+6
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.
2014-04-23Eliminated many warningsOren Hurvitz8-5/+25
2014-04-12BulletSim: reduce the terrain collison margin to be the same as otherRobert Adams1-1/+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.
2014-04-10BulletSim: small tweek to avatar height reduce feet embedded into prims.Robert Adams1-1/+1
This adjustment makes a default, shoeless avatar stand properly on a prim for the various heights (0% to 100% in the appearance adjustment).

2014-04-02BulletSim: make avatar physical shape to be a rectangle rather thanRobert Adams3-11/+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.
2014-03-23BulletSim: fix problem where axis constraints were also constrainingRobert Adams1-3/+5
linear motion. The code was limiting linear motion to be only in the positive direction for any axis that was constrained.

2014-02-11BulletSim: the minimum vehicle velocity was set too low so moving slowRobert Adams2-1/+12
was getting zeroed too easily. Added VehicleMinVelocity parameter.
2014-01-29BulletSim: default physical terrain implementation to heightmap.Robert Adams2-1/+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.
2014-01-10Fix crash in BulletSim which sometimes happens making a linkset physicalRobert Adams1-7/+32
(like sitting on and activating a vehicle) and crossing borders. This keeps better bookkeeping on compound shapes so BulletSim can identify them when being freed.
2013-12-26varregion: many more updates removing the constant RegionSize and replacingRobert Adams2-1/+2
with a passed region size. This time in the map code and grid services code.
2013-12-14Fix TestSitAndStandWithNoSitTarget NPC and SP tests.Justin Clark-Casey (justincc)1-8/+1
These stopped working because current code calculates sit heights based on avatar physics rather than appearance data. Also changed BasicPhysics to not divide Z param of all set sizes by 2 - there's no obvious good reason for this and basicphysics is only used in tests

to check for border crossings based on the size of the region.
2013-11-01add null check for jpeg2000 sculpt image decode failure. Note: the ↵dahlia1-0/+9
j2kDecodeCache folder should be cleared after updating to this revision so that sculpts containing alpha can be re-decoded and successfully meshed.

2013-10-26BulletSim: update collision flags to make sure they fit in the shorts provided.Robert Adams1-7/+7
2013-10-23BulletSim: change collision flags for groundplane to not interact with ↵Robert Adams4-7/+13
static objects. Reorder collision flag setting code for terrain to fit pattern used elsewhere.
2013-10-15BulletSim: implement the SL bug where VEHICLE_HOVER_UP_ONLY disablesRobert Adams1-0/+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.

2013-09-20BulletSim: reduce avatar walking stopped threshold.Robert Adams2-0/+4
Add parameter for setting the walking stopped threshold. This fixes the slight jump when an avatar stops walking.
2013-09-20BulletSim: zero velocity when avatar not moving.Robert Adams1-0/+1
This fixes a movement jitter that happens when an avatar is standing on a tilted surface.
2013-09-11BulletSim: remove collision cache clearing logic for physical objects.Robert Adams1-2/+5
This fixes constraints from getting messed up when properties change.
2013-09-11BulletSim: add ClearCollisionProxyCache function to API.Robert Adams4-2/+35
Add proxy cache clearing when some properties are changed. This fixes a problem where objects would stop colliding of they were moved with setPosition mulitple times.

2013-09-11BulletSim: adjust avatar capsule height calculation to be closer to defined ↵Robert Adams2-7/+12
SL heights. Correct BSParam avatar height defaults to be what's in OpenSimDefaults.ini.
2013-09-11BulletSim: add extended physics function physGetLinkType(linkNum). Add ↵Robert Adams3-23/+144
implementation of physChangeLinkParams() in BSLinksetConstraint.

as case variables in switch statements.
2013-09-11BulletSim: add physChangeLinkParams to set individual parameters on link ↵Robert Adams5-73/+153

2013-09-11BulletSim: add physChangeLinkSpring to change linkset link to be a spring ↵Robert Adams4-11/+128
constraint. Add implementation to create spring constraint. Send up property updates for linkset children at the end of flexible linkset links. The simulator probably doesn't do the right thing yet.
2013-09-11BulletSim: Linkset.Refresh() calls internal ScheduleRebuild() to recreate ↵Robert Adams2-14/+14
the linkset physics at next PostTaint time. Replace the existing calls to ScheduleRebuild to be calls to Refresh(). This allows external routines to make changes to parameters and then cause the linkset to rebuild.
