2013-07-22Add experimental stubs for an extension function interface on bothRobert Adams2-0/+15
PhysicsScene and PhysicsActor.
2013-07-22BulletSim: freshen up the code for constraint based linksets.Robert Adams3-23/+64
2013-07-18BulletSim: add position resetting for stationary avatars so they don'tRobert Adams2-5/+20
move around when standing on a stationary object. Create proper linkage between BSCharacter and its actor by generating a UpdatedProperties event the same way BSPrim does.
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).
2013-07-08minor: remove some mono compiler warnings in OdePluginJustin Clark-Casey (justincc)2-2/+1
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.
2013-07-07BulletSim: rename position and orientation variables to remove theRobert Adams3-95/+71
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
effect if LinksetOffsetCenterOfMass=false (the default).
2013-07-06BulletSim: comments and non-functional changes working toward the ↵Robert Adams4-20/+39
center-of-gravity implementation.
2013-07-06BulletSim: non-functional updates. Comments and formatting.Robert Adams4-43/+67
Update TODO list.
2013-06-30BulletSim: add the reset of the last commit for flush log file problems.Robert Adams2-2/+2
Fix small typo in one log message.
2013-06-30BulletSim: fix an occasional crash with flushing log files.Robert Adams1-4/+2
2013-06-30BulletSim: remove the handle to the vehicle actor and cause routinesRobert Adams2-32/+70
that need it to look it up.
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.
2013-06-30BulletSim: add inTaintTime parameter to collision cache clear function.Robert Adams1-3/+3
2013-06-21BulletSim: move new linear deflection code to own routine.Robert Adams1-29/+35
Remove VehicleForwardVelocity changed storage since the value will be modified as movement is processed.
2013-06-20BulletSim: Implementation of Linear Deflection, it is a partial help for the ↵Vegaslon1-5/+33
vehicle tuning diffrence between Opensim and Second life. Signed-off-by: Robert Adams <Robert.Adams@intel.com>
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.
2013-06-11BulletSim: when meshing or asset fetching fails, include positionRobert Adams2-14/+30
and region with the offending object's name in the error message.
2013-06-10BulletSim: add failure flag for meshing failure vs asset fetch failureRobert Adams4-34/+51
so error messages make more sense. Change some BulletSim status log messages from WARN to INFO. Update TODO list.
2013-06-05BulletSim: default PhysicsTimeStep to same as the simulator'sRobert Adams1-1/+1
heartbeat timestep when running the physics engine on a separate thread. This reduces the occurance of heartbeats that happen when there is no physics step which is seen as vehicle jerkyness.
2013-06-05BulletSim: fix corner case when rebuilding a compound linkset whileRobert Adams1-11/+46
a mesh/hull while a mesh or hull is being rebuilt when its asset is fetched. This fixes a 'pure virtual function' crash when changing physical state of complex linksets that include many meshes.
2013-06-01BulletSim: experimental movement of physics execution off of heartbeatRobert Adams3-73/+209
thread. Off by default until more testing. Setting "[BulletSim]UseSeparatePhysicsThread=true" causes the physics engine to be called on its own thread and the heartbeat thread only handles the reporting of property updates and collisions. Physics frame rate is about right but physics execution time goes to zero as accounted by the heartbeat loop.
2013-05-28BulletSim: don't zero motion when changing vehicle type.Robert Adams1-1/+4
Some vehicle scripts change type on the fly as an easy way of setting all the parameters (like a plane changing to a car when on the ground).
2013-05-27BulletSim: default using mesh asset hulls to 'true'. This means that,Robert Adams1-2/+2
if the mesh asset specifies physics hulls, BulletSim will fetch and use same rather than approximating the hulls. If physics hulls are not specified, the representation will fall back to the regular physics mesh.
2013-05-26BulletSim: enable GImpact shape for prims with cuts. Include DLLs and SOsRobert Adams1-1/+1
which recompute GImpact shape bounding box after creation as Bullet doesn't do that itself (something it does for nearly every other shape). Now, physical prims without cuts become single mesh convex meshes. Physical prims with cuts become GImpact meshes. Meshes become a set of convex hulls approximated from the mesh unless the hulls are specified in the mesh asset data. The use of GImpact shapes should make some mechanical physics more stable.
2013-05-24Meshmerizer: remember to add the copied hull verts to the list of hulls.Robert Adams1-0/+1
2013-05-24BulletSim: add VehicleInertiaFactor to allow modifying inertia.Robert Adams2-1/+5
Another parameter for vehicle operation tuning. Default to <1,1,1> which means nothing is different under normal use.
2013-05-24BulletSim: properly set mesh hash key in use tracking structure.Robert Adams1-1/+4
Shouldn't see any functional difference.
2013-05-24Meshmerizer: add INI parameter to enable DEBUG mesh detail logging.Robert Adams1-3/+6
Default to off. To turn mesh parsing DEBUG detail logging on, add [Mesh] LogMeshDetail=true to the INI file.
2013-05-24change a hull debugging message to Debug instead of Infodahlia1-1/+1
2013-05-24correct some errors in decoding of mesh asset convex decomposition datadahlia1-53/+83
2013-05-23add decoder for bounding convex hulldahlia1-4/+53
2013-05-23Add DEBUG level logging in Meshmerizer for mesh parsing. There isRobert Adams1-2/+25
a compile time variable to turn this logging off if it is too spammy.
2013-05-23BulletSim: add locking around Meshmerizer use to eliminate possible raceRobert Adams1-145/+157
condition when extracting the convex hulls.
2013-05-22BulletSim: correct errors caused by misspelled INI parameter spec.Robert Adams2-4/+7
Add debugging messages for hull asset use.
2013-05-22BulletSim: add code to experimentally use asset hull data.Robert Adams2-4/+54
Default to 'off' as it needs debugging.
2013-05-22BulletSim: fix problem with walking up stairs that are orientedRobert Adams1-2/+9
in certain directions. The problem was really that the avatar capsule orientation was being set incorrectly.
2013-05-21Revert "BulletSim: add code to experimentally use asset hull data."Robert Adams2-54/+4
This reverts commit 2fd8819a043269f9308cb46c71893e6eb35a426e. Remove this code until I can figure out why the references that are clearly in prebuild.xml doesn't work for the 'using OpenSim.Region.Physics.Meshing' in BSShape.cs.
2013-05-21BulletSim: add code to experimentally use asset hull data.Robert Adams2-4/+54
Default to 'off' as it needs debugging.
2013-05-21BulletSim: add gImpact shape type. Add logic to use gImpact shapeRobert Adams7-14/+167
for prims that have cuts or holes. Default logic to 'off' as it needs debugging.

2013-05-18remove duplicate hull scalingdahlia1-3/+3
2013-05-18add prototype code to decode convex hulls from mesh assets. Please do not ↵dahlia1-21/+110
use yet; the interface will be defined in a later commit.
2013-05-17BulletSim: fix BulletSim crashing if there is no [BulletSim] sectionRobert Adams2-8/+12
in any INI file. Update TODO list.
