* BulletSim: add osGetPhysicsEngineType() LSL function and updateRobert Adams2013-01-112-2/+3
| | | | | | | | the physics engines to return the name that is specified in the INI file ("physics = XXX") as the type of engine. This os function is a little different than the others in that it does not throw an exception of one is not privilaged to use it. It merely returns an empty string.
* Stop logging spurious asset data for {0} is zero length error for sculpts/meshJustin Clark-Casey (justincc)2012-11-281-0/+5
| | | | | | | | ODEPrim, for instance, always hits this code path twice at the moment Firstly before any sculpt data has been loaded (hence the spurious message) Secondly when any sculpt data has been loaded or failed to load (when the message would be valid). Hence comment this out and rely on the message in ODEPrim.MeshAssetReceived() instead (though this is not ideal since it requires all physics plugins to copy/paste similar code).
* Consistenly make NUnit test cases inherit from OpenSimTestCase which ↵Justin Clark-Casey (justincc)2012-11-241-1/+2

* Log warning if mesh/sculpt asset couldn't be found by ↵Justin Clark-Casey (justincc)2012-10-301-0/+6
| | | | | | ODEPrim.MeshAssetReceived() callback. Presumably this is now more useful if the false positive from the old method of loading mesh assets have been eliminated.
* Add asset != null check to ODEPrim.MeshAssetReceived instead of throwing ↵Justin Clark-Casey (justincc)2012-10-301-1/+1
| | | | | | exception. In some cases (such as failure to receive response from asset service), it is possible for a null to be returned from IAssetService.Get(string, object, AssetRetrieved).
* Make MeshAssetReceived private.Justin Clark-Casey (justincc)2012-10-301-1/+1
| | | | Keep methods private unless they need to be opened up to external callers. Reduces analysis complexity.

* av_av_collisions_off = false OdePhysics Settings in OpenSimDefaults.ini - ↵teravus2012-10-091-2/+9
| | | | No Avatar Avatar Collisions. This causes avatar to be able to walk through each other as if they're ghosts but still interact with the environment.
* Add config option to plant avatar where they are reducing avatar avatar ↵teravus2012-10-092-3/+9
| | | | 'pushability' av_planted see OpenSimDefaults.ini. Use when you have unruly visitors that rudely push each other around. Still allows a small amount of movement based on the avatar movement PID controller settings. You can increase the spring tension in the PID controller and really prevent any movement if you would like.
* Soliciting for comments on smoothness of physics objects for this build.teravus2012-10-032-8/+46
| | | | | This introduces expected contact point hints to the ODE Collider to better determine when to throttle updates as excessive. This /should/ smooth physics objects out again, however, I cannot know every configuration of OpenSimulator, so I'm requesting that testers please examine this change on their build. Thanks!
* I propose that 0.5m/step change for linear velocity is too big of a change ↵teravus2012-10-031-1/+15
| | | | to control the reporting of a new angular velocity. I think that this could be here for one of two reasons, 1. vehicles and llMoveToTarget with axis lock, or 2. To attempt to make things look more stable in the physics scene then they really are, however, this also really affects the angular velocity reporting negatively causing things to spin wildly and jump back into place repeatedly. To compromise, if the prim is a vehicle or is being used as a motor target, the original functionality is still applied. If that's not the case, angular velocity is reported with a linear velocity of 0.02m/step. To be clear on the effect of the physical world... When you push things, there's still a lag time where you walk into the object but once the object is in motion, it begins to move as you would expect so results in slightly more realistic motion.
* Minor Modification, switch /2 to 0.5f in ODEPrim.Velocityteravus2012-10-021-4/+4

* Remove the LandGeom checks in OdeScene - these are pointless since LandGeom ↵Justin Clark-Casey (justincc)2012-07-271-4/+2
| | | | | | | is always IntPtr.Zero and contacts returned always have a valid geometry. Possibly this was for a feature that was never implemented or was otherwise removed. Thanks to SignpostMarv for the spot of the warning that shows this parameter was never changed.
* Add check so Ode does not try to simulate after it has been Dispose()'ed. ↵Robert Adams2012-07-261-0/+9
| | | | Fixes exception that happens when shutting down region (improvements from last patch)
* Move update of the final optional ODE total frame stat inside the OdeLock ↵Justin Clark-Casey (justincc)2012-06-291-3/+3
| | | | rather than outside to avoid a very occasional race condition with the stat collection thread
* refactor: rename _collisionEventPrim to m_collisionEventActors and ↵Justin Clark-Casey (justincc)2012-06-291-12/+12
| | | | | | _collisionEventPrimChanges to m_collisionEventActorsChanges to reflect their actual contents. These dictionaries handle all actor types, not just physical prims.
* Fix a regression where we stopped removing avatars from collision event ↵Justin Clark-Casey (justincc)2012-06-291-1/+1
| | | | | | | reporting on logout, rather than stopping clearing their collision events. This occurred in b18c8c8 (Thu May 17 2012). This was a cause of very occasional race conditions and likely memory leakage as clients came and went from the region.
* Add optional total avatars, total prims and active prims stats to ODE plugin.Justin Clark-Casey (justincc)2012-06-011-0/+21
| | | | | These will act as a sanity check with the main scene stats, to show that physics scene entities are being managed properly. Total prims will not match scene total prims since physics total does not include phantom prims
* If OdeScene.Near() returns no collision contacts, then exit as early as ↵Justin Clark-Casey (justincc)2012-06-011-0/+4
| | | | possible. All subsequent code is only relevant if there are contacts.
* Add optional stat for the other collision time per frame not spent in ODE ↵Justin Clark-Casey (justincc)2012-06-011-1/+16

* Add total ODE frame time optional stat, as a sanity check on the main scene ↵Justin Clark-Casey (justincc)2012-06-011-7/+21

* Break down native ODE collision frame time stat into native space collision ↵Justin Clark-Casey (justincc)2012-06-011-4/+22
| | | | and geom collision stats
* Rename new collision stats to 'contacts' - there are/can be multiple ↵Justin Clark-Casey (justincc)2012-06-011-6/+6
| | | | contacts per collision and this is what is actually being measured.
* Stop adding an unnecessary duplicate _perloopcontact if the avatar is ↵Justin Clark-Casey (justincc)2012-06-011-9/+4
| | | | | | standing on a prim. This has already been added earlier on in the method.
* minor: comment out currently unused OdeScene.sCollisionDataJustin Clark-Casey (justincc)2012-06-011-9/+9

* Add ODE avatar and prim collision numbers if extra stats collection is enabled.Justin Clark-Casey (justincc)2012-06-011-5/+34
|
* Fix OdeScene.GetTopColliders() to return the top 25 colliders rather than ↵Justin Clark-Casey (justincc)2012-06-011-19/+13
| | | | | | | | the first 25 that had non-zero collision scores. Also zeros collisions scores on all prims after report collection, not just the top 25. As before, this collision scores are only reset after a report is requested, which may give unrealistic numbers on the first request. So to see more realistic scores, ignore the first report and then refresh the request after a couple of seconds or so.
* Add an optional mechanism for physics modules to collect and return ↵Justin Clark-Casey (justincc)2012-05-311-10/+129
| | | | | | | | | | | arbitrary stats. If active, the physics module can return arbitrary stat counters that can be seen via the MonitoringModule (http://opensimulator.org/wiki/Monitoring_Module) This is only active in OdeScene if collect_stats = true in [ODEPhysicsSettings]. This patch allows OdeScene to collect elapsed time information for calls to the ODE native collision methods to assess what proportion of time this takes compared to total physics processing. This data is returned as ODENativeCollisionFrameMS in the monitoring module, updated every 3 seconds. The performance effect of collecting stats is probably extremely minor, dwarfed by the rest of the physics code.
* refactor: move EventQueueGet path generation into common method. Rename ↵Justin Clark-Casey (justincc)2012-05-181-1/+1
| | | | some local variables in line with code conventions. Add commented out EQG log lines for future use.
* Don't eagerly clear frame collision events when physics actors subscribe and ↵Justin Clark-Casey (justincc)2012-05-171-2/+8
| | | | | | | | unsubscribe from collisions, in order to avoid a race condition. Since this is done directly from ScenePresence, it can lead to a race condition with the simulator loop. There's no real point doing it anyway since the clear will be done very shortly afterwards by the simulate loop and either there are no events (for a new avatar) or events don't matter (for a departing avatar). This matches existing behaviour in OdePrim
* Restore _parent_scene.actor_name_map[prim_geom] = this; accidentally removed ↵Justin Clark-Casey (justincc)2012-04-241-0/+1
| | | | | | | | from ODEPrim.SetGeom. This occurred in 7a574be3fd from Sat 21 Apr 2012. This should fix collision detection. Mnay thanks to tglion for the spot and the fix in http://opensimulator.org/mantis/view.php?id=5988
* Comment out spurious Body != IntPtr.Zero code after disableBody(), since ↵Justin Clark-Casey (justincc)2012-04-212-10/+20
| | | | disableBody() sets Body == IntPtr.Zero on all code paths.
* refactor: Simplify ODEPrim.AddChildPrim() by returning early where appropriate.Justin Clark-Casey (justincc)2012-04-211-115/+117

* Remove redundant prim_geom != IntPtr.Zero checks in ODEPrim.Justin Clark-Casey (justincc)2012-04-211-116/+88
| | | | | | prim_geom == IntPtr.Zero only before a new add prim taint is processed (which is the first taint) or in operations such as scale change which are done in taint or under lock. Therefore, we can remove these checks which were not consistently applied anyway. If there is a genuine problem, better to see it quickly in a NullReferenceException than hide the bug.
* If a physical prim is manually moved (e.g. by a user) then set the geometry ↵Justin Clark-Casey (justincc)2012-04-201-12/+10
| | | | | | | position as well as the body position This is necessary to stop the moved prim snapping back to the original position on deselection if moved only once This resolves http://opensimulator.org/mantis/view.php?id=5966
* refactor: precalculate the fixed movement factor for avatar tilting ↵Justin Clark-Casey (justincc)2012-03-202-8/+16
