Robert Adams bbc5a5089f BulletSim: Rename some of the interface structures (BulletWorld, ...)
to get ready for...
Start creation of BulletAPITemplate. This defines the abstract interface
functions. Following commits will move over to the new interface.
This will enable switching between the managed and unmanaged version of
Bullet.

Robert Adams 4759a8acee BulletSim: Default avatar density changed to 3.5 which is WAY closer
to the SL value.
Fixed frictin values for physical materials which were just wrong
which caused things that should have slipped to not.

Robert Adams 80cee1b85a BulletSim: Fix single physical prim reporting its mass as zero.
Properly return root mass as mass of just the root prim rather
than the mass of the linkset. SOG has the logic to add the masses
together to get the linkset mass.
Update TODO list.

teravus 9318870607 * Update BulletSimN terrain implementation to default to Heightfield, it's less CPU intensive. 2012-12-23 16:17:18 -05:00
teravus 1a841dfc59 * Update Example to include BulletSimN option and description. 2012-12-23 15:44:29 -05:00
teravus cb4949fc15 * Added third party license for Bullet-xna. 2012-12-23 15:24:15 -05:00
teravus 92e4f9f412 * Initial commit of BulletSimN (BulletSNPlugin). Purely C# implementation of BulletSim. This is designed to be /as close as possible/ to the BulletSim plugin while still being entirely in the managed space to make keeping it up to date easy as possible (no thinking work). This implementation is /slower/ then the c++ version just because it's fully managed, so it's not appropriate for huge sims, but it will run small ones OK. At the moment, it supports all known features of BulletSim. Think of it like.. POS but everything works. To use this plugin, set the physics plugin to BulletSimN. 2012-12-23 15:21:25 -05:00

Robert Adams 30807b81cc BulletSim: modify avatar motor code to make falling movement better. Clean up some usages. Disable motor when done. 2012-12-22 17:09:40 -08:00
Robert Adams 144322a7c9 BulletSim: remove post step one-time taints (doesn't make any sense). Rename pre and post step event invocation routines to Trigger* to be consistant. Remove old, unused code. 2012-12-22 17:07:52 -08:00
Robert Adams 16e49035f7 BulletSim: add Enabled parameter and operation to motors. 2012-12-22 17:06:13 -08:00
Robert Adams 3e3c168987 Add helper routine Util.InRange() 2012-12-22 17:04:53 -08:00
Robert Adams 5b2cbc0ae6 BulletSim: remove all special vehicle code from BSScene. Replace per-frame updates for vehicles with per-frame action registration. One fewer special case. 2012-12-21 23:24:31 -08:00
Robert Adams a54392d7cc BulletSim: remove the movement decay while flying. Made flying slow down over time. 2012-12-21 23:05:05 -08:00
Robert Adams 37fb691ba5 BulletSim: Fix llApplyImpulse so it works after the first impulse. The problem was Bullet deactivating the object between the pushes (when, as far as the physics engine is concerned, it isn't moving). 2012-12-21 23:03:27 -08:00
Robert Adams 3d659fe97d BulletSim: add BSPhysObject code to manage registrations of preStep events. Use same to implement setForce and setTorque so the values are restored at the beginning of each step (since Bullet zeros forces applied last step). Simplify implementation of AddForce and AddTorque by relying on the addition of forces in Bullet. 2012-12-21 17:27:53 -08:00
Robert Adams 6dbf9c8ed4 BulletSim: repair vehicle problems introduced in previous 'improvements'. Fix line endings in BSParams. 2012-12-21 15:21:32 -08:00
Robert Adams ae4d932e7f BulletSim: Move all the parameter variables, tables and get and fetch logic to a separate, static class for easier addition and to remove all that bulk from the BSScene class. 2012-12-21 13:35:44 -08:00
Robert Adams 2e3e95e846 BulletSim: small fix to avatar movement motor use which keeps avatar from flying up forever. This doesn't fix the overall problem but keeps avatar flying from being totally unusable. 2012-12-21 10:04:12 -08:00
Robert Adams 8c99f63239 BulletSim: avatar movement smoothed with motor that modifies avatar velocity to target velocity. Fails in incorporating physical world effects (gravity) so avatar doesn't fly correctly. 2012-12-21 10:00:03 -08:00
Robert Adams b4f8a05e9a BulletSim: Better detail logging of VMotor actions. 2012-12-21 09:56:31 -08:00
Robert Adams 750492796d BulletSim: begin movement of parameters from pinned memory block to variables all in managed code. Add note to TODO list to remember to do the rest. Other updates to TODO list. 2012-12-21 09:55:20 -08:00
Robert Adams 9d2f569d60 BulletSim: fix incorrectly defined property changed flag. 2012-12-20 16:06:52 -08:00
Robert Adams e522bdb96a BulletSim: Check for unspecified TimeScale in BSVMotor and don't scale if not specified. Add test dump routine. Don'e zero current and target values when error goes to zero as the values could be used externally to store the actual target values, etc. 2012-12-20 16:05:33 -08:00
Robert Adams a5b2539cf9 BulletSim: replace use of funky nullable values for vehicle property update control (m_known* stuff). Bitmaps will be quicker to test and to clear. 2012-12-20 10:32:33 -08:00
Robert Adams e73dac4deb BulletSim: angularMotorUp working again (seems a little slow as it takes longer than timescale to correct, but getting better). Disabled angularDeflection (need to resolve interactions between angular corrections). Update TODO list. 2012-12-20 10:19:16 -08:00
Robert Adams b7ad44e3a6 BulletSim: reorganize motor step code to separate error computation allowing subclass for PID error correction. 2012-12-20 08:35:36 -08:00
Robert Adams a9b9c0f035 BulletSim: improve angularVerticalAttraction calculation to compute angular correction velocity rather than estimating correction (excuse to use trig functions). 2012-12-18 23:05:59 -08:00
Robert Adams 7b84bcfbb8 BulletSim: initial implementation of a PID motor. Not hooked up yet. 2012-12-18 22:59:59 -08:00
Robert Adams cf89e29ac3 BulletSim: comments and TODO list update 2012-12-18 19:25:51 -08:00
Robert Adams d15bfcf614 Replace axis rotation numeric constants (STATUS_ROTATE_XYZ) with symbols. Also made it so llSetStatus() can individually enable disable rotation axi using the bitmask of flags. 2012-12-18 19:25:40 -08:00
Justin Clark-Casey (justincc) ae67435146 Disable UDPPacketBuffer pooling for now to resolve an issue on Windows of interference between incoming packets.
On Windows, concurrent multi-threaded processing of inbound UDP somehow allows different data input processing to interfere with each other.
Possibly the endpoint reference is being switched, though I don't yet know the mechanism.  Not seen on Mono.
Also resolveable by setting RecyclePackets = false or RecycleBaseUDPPackets = false in [PacketPool]
Or async_packet_handling = false in [ClientStack.LindenUDP]
For now, will simply disable this particular pooling though will revisit this issue.

Justin Clark-Casey (justincc) 235afebf03 Merge branch 'master' of ssh://opensimulator.org/var/git/opensim 2012-12-17 22:19:42 +00:00
Robert Adams 8653ea93b2 BulletSim: apply friction to linear and angular motion before returning advanced motor value. This seems to be the problem with BulletSim vehicles turning too quickly. Also removed the configuration parameter that controlled the timestep scaling kludge for angular velocity that was added to research the question of quick turning. 2012-12-17 13:51:39 -08:00
Justin Clark-Casey (justincc) e6fd8365af Extend default 1 second wait for event completion to other thread script reset (as called by llResetOtherScript()).
As with script stop (via llDie()) aborting other scripts event threads, llResetOtherScript() can also abort any current event thread on another script.
On mono 2.6, 2.10 and possibly later this may cause locking problems in certain code areas.
This commit reuses the recently introduced [XEngine] WaitForEventCompletionOnScriptStop to make this a 1 sec timeout, rather than 0 secs.

Robert Adams 11532a4390 BulletSim: fix vehicles going underground when unsat. Problem was that, when doing unsit, the order of operations on the prims and the vehicle is very chaotic and not in a good order so the root prim was being left physical and thus it fell for a bit. Also changed default of velocity scaling to be closer to the movement standard. 2012-12-17 13:22:04 -08:00
Robert Adams 021623a17d BulletSim: fix vehicles being shot in the air at border crossings because of mis-application of correction to postion for below groundness. 2012-12-16 22:31:22 -08:00
Robert Adams 2b8efa24dd BulletSim: add parameter to UpdateProperties call into the linkset so changes from the physics engine can be differentiated from changes made by the user. This eliminates a linkset rebuild loop. Also add logic to not rebuild or freak out when the object/linkset crosses a terrain boundry. 2012-12-16 21:19:13 -08:00
Robert Adams 3f2aaffd4d BulletSim: add even more to the TODO list. 2012-12-16 21:19:13 -08:00
Robert Adams 7ed860d3ac BulletSim: add check for border crossing in character position sanity check. 2012-12-16 21:19:12 -08:00
Robert Adams 4cbc5082ff BulletSim: refactor to combine common terrain height testing code. Add function to test if a position is over known terrain. 2012-12-16 21:19:12 -08:00
Robert Adams 8a95953bb7 BulletSim: experimentally remove unit displacement from prim border crossing test. This seems to cause border crossing to be sensed either a little early or a little late depending on which directin the object is moving. If border crossings become totally borked or someone remembers why this was displacement was done, revert this change. 2012-12-16 21:19:12 -08:00
Robert Adams 21dc5f4a1a Add stack dump function that takes an alternate printer outter. I've found that log4net can be slowish so, if one is generating A LOT of debug output, alternate printers are better 2012-12-16 21:19:11 -08:00
Robert Adams f3b1efd889 BulletSim: remove some errors on shutdown by moving terrain destruction until after physical object destruction. TerrainManager also made disposable and that feature used. 2012-12-16 21:19:11 -08:00
Robert Adams ace1f1e931 BulletSim: rip out old code for linkset child position fetching. BulletSim doesn't need to do that bookkeeping because SOG/SOP already does it. 2012-12-16 21:19:10 -08:00
Justin Clark-Casey (justincc) 1a262bdde7 Make WebStatsModule properly handle scenes added or removed after initial startup.
This may have been the cause of the DivByZero in http://opensimulator.org/mantis/view.php?id=6460

Justin Clark-Casey (justincc) 494e6a5f11 minor: If the physics module tells us that an object has gone out of bounds, more helpfully log the name, id, position and region of that object. 2012-12-15 00:30:17 +00:00
