8d72145112 If Bullet is running on its own thread, use a reset event to control timing rather than a sleep. 
In theory, there should be no difference between these mechanisms.
However, on at least Mono 3.2.8 waiting via an event appears to be much more accurate.

23561239ee Make BulletSim thread be ThreadPriority.Highest if running 
Will only effect Windows or mono with a patch such as https://gist.github.com/justincc/31e52218d098529b4696 applied
For test purposes

4b04d22899 Don't need to check separate physics status in bulletsim update since that method is only run for an indepndent thread anyway. 
Also remove bulletsim monitored thread from watchdog on shutdown.

6e6512eb4a Make bulletsim thread alarm if no update for 5 seconds. 
The cost is minimal (also done for scene loop) at the benefit of telling us if this thread simply stops for some reason.

29400538b7 minor: fix indenting from previous commit b08ab1e 2014-09-03 23:37:20 +01:00

b08ab1e375 If BulletSim is running on its own threads, start this thread via the thread watchdog. 
This allows us to see the presence of the permanent thread via the "show threads" console comand.
Also adds the region name to the thread name.

50ed97aa1a BulletSim: thread safe handling of list of avatars. 
Fix for 7284 which is an enumeration exception when starting up a region.

3654ae8d8c Allow the "debug scene set physics false|true" command to work when bulletsim physics is running in a separate thread. 
This will also allow the "disable physics" setting in the region debug viewer dialog to work in this circumstance.

481b7c71c3 BulletSim: add some locking for collision lists to prevent collsions 
from locking up when running BulletSim on a separate thread.

fab0389cb1 BulletSim: add locking of PhysObjects while processing simulation 
step updates and collisions. This is an attempt to fix a crash reported
by Justin when doing high velocity teleports.

0842e2e15b BulletSim: default physical terrain implementation to heightmap. 
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.

2d2bea4aa7 varregion: many more updates removing the constant RegionSize and replacing 
with a passed region size. This time in the map code and grid services code.

f2810bf03a varregion: add plumbing to pass region size from Scene down to the 
physics engine.
Older physics engines will default to the legacy region size.
Update BulletSim to use the new region size information.

995314f91f BulletSim: add ID parameter to TaintedObject calls so logging will include LocalID of object which created the taint. 2013-09-11 09:12:03 -07:00

4781297b4e BulletSim: Extension parameters passed through the classes made to pass just and array of objects rather than a mixture of parameters and array. Makes understanding and parsing what is being passed much easier. 2013-09-11 09:12:02 -07:00

455d36c4c7 BulletSim: add physChangeLinkParams to set individual parameters on link constraints. Not fully functional. Remove double definition of ExtendedPhysics parameters by having BulletSim reference the optional module (addition to prebuild.xml and usings). 2013-09-11 09:11:52 -07:00

f3cc20050e BulletSim: initial implementation of physChangeLinkFixed that resets a linkset's link back to a fixed, non-moving connection. 2013-09-11 09:11:45 -07:00

0882cf0fc3 BulletSim: add some protections for processing when shutting down. 
Attempt to fix Mantis 6740 (http://opensimulator.org/mantis/view.php?id=6740).

7c3b71d294 BulletSim: add physical object initialized flag so updates and collisions 
don't happen until the object is completely initialized.

This fixes the problem of doing a teleport while the simulator is running.
The destruction of the physical object while the engine is running means
that the physics parameter update would overwrite the new position of the
newly created avatar.

24df15dab7 BulletSim: add implementation of 'physSetLinksetType' and 'physGetLinksetType' 
and processing routines in BulletSim.
Add linkset rebuild/conversion routine in BSLinkset.

2c8bf4aaa6 BulletSim: fix small bug where everything looked like it was colliding 
before the first simulator step.

fad4241e4e BulletSim: make all the different angularVerticalAttraction algorithms 
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).

97698ae311 BulletSim: More tweaking on center-of-mass. Almost there. Changes have no effect if LinksetOffsetCenterOfMass=false (the default). 2013-07-06 08:25:15 -07:00

8eb86c9ec9 BulletSim: add the reset of the last commit for flush log file problems.

795acaa6aa BulletSim: add failure flag for meshing failure vs asset fetch failure 
so error messages make more sense.
Change some BulletSim status log messages from WARN to INFO.
Update TODO list.

07058b044b BulletSim: experimental movement of physics execution off of heartbeat 
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.

9de3979f5b BulletSim: add gImpact shape type. Add logic to use gImpact shape 
for prims that have cuts or holes. Default logic to 'off' as it
needs debugging.
