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.

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.

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

This occurred in 7a574be3fd from Sat 21 Apr 2012.
This should fix collision detection.

rather than setting phantom.
This was an oversight when removing some race conditions from PhysicsActor setting recently.
Regression tests extended to probe this code path.
Extending regression tests required implementation of a BasicPhysicsPrim (there was none before). However, BasicPhysics plugin is still of no current practical use other than to fill in as a component for other parts of regression testing.

disableBody() sets Body == IntPtr.Zero on all code paths.
|
| | |
|
| |
|
|
|
|
| |
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.

This is necessary to stop the moved prim snapping back to the original position on deselection if moved only once

It seems that ODE calls the avatar collision handling routine even
if there are no collisions. This causes the animation to be updated.
So, for instance, going from HOVER to FLY is caused by the physics engine
calling the collision routine each frame with 0 collisions.

Have to lock m_MeshToTriMeshMap as property is static and with more than one region two scene loops could try to manipulate at the same time.

On the first frame, all startup scene objects are added to the physics scene.
This can cause a considerable delay, so we don't start raising the alarm on scene loop timeouts until the second frame.
This commit also slightly changes the behaviour of timeout reporting.
Previously, a report was made for the very first timed out thread, ignoring all others until the next watchdog check.
Instead, we now report every timed out thread, though we still only do this once no matter how long the timeout.

This uses the same approach as ODE.

In over 4 years this never progressed beyond an unimplemented stub.
This doesn't mean that it can't come back if someone is interested in implementing PhysX support.

whether the process is 32-bit or 64-bit
In theory, this means that a 64-bit Windows OS user can now run OpenSim.exe with ODE and use more than 2 (or 3) GB of memory.
However, this is completely untested since I don't currently own a 64-bit Windows box. Feedback appreciated.
Using OpenSim.32BitLaunch.exe should continue to work. Other platforms are unaffected.
This will currently not work with sqlite - I will add that too if this works.

If velocity reaches 256 in any vector then bad things happen with ODE, so we now clamp this value.
In addition, a falling avatar is clamped by default at 54 m/s, which is the same as a falling skydiver.
This also appears to be the value used on the linden lab grid.

prevent ODE crashes on simulators running more than one region.
It turns out that calls to Collide() are not thread-safe even for objects in different ODE physics worlds due to ODE static caches.
For simulators running multiple regions, not serializing calls from different scene loops will sooner or later cause OpenSim to crash with a native stack trace referencing OBBCollider.
This affects the default OPCODE collider but not GIMPACT. However, GIMPACT fails for other reasons under some current simulator loads.
ODE provides a thread local storage option, but as of ODE r1755 (and r1840) DLLs compiled with this crash OpenSim immediately.
