Robert Adams 7a5f598399 BulletSim: move logic for IsColliding, CollidingGround and CollidingObj from individual sub-classes and up to parent BSPhysObject class. 2012-12-27 22:12:27 -08:00
Robert Adams 5afab9bcfe Add check to always push terse updates for presences that have new velocities of zero. 2012-12-27 22:12:27 -08:00
Robert Adams e57c0e6731 BulletSim: fix buoyancy so it's properly set by a script when an
object is selected.
Update TODO list.
2012-12-27 22:12:26 -08:00
Robert Adams 7230990679 BulletSim: fix odd code that wasn't really recomputing the mass of a
rebuilt linkset. I was burnt by making get/set methods with side
effects. I should know better.
2012-12-27 22:12:26 -08:00
Robert Adams f3baed5827 BulletSim: add physical parameter min/max constants in BSParam. I just don't like raw numbers scattered around the code. 2012-12-27 22:12:25 -08:00
Robert Adams e98e223927 BulletSim: complete applyImpulse function in BSCharacter (like I said
I did last time).

teravus 29cdf0f3dd * Merges BulletSim Updates to BulletSimN(BulletSNPlugin) 2012-12-18 15:00:10 -05:00
Robert Adams 225b564573 BulletSim: scale the force for external AddForce by the simulation
step time so it will be applied completely the next step. The internal
AddForce routine does not scale the force.

Robert Adams d1ede1df3a BulletSim: make llBuoyancy work. For some reason, Bullet resets an
object's individual gravity to the world gravity when the object
is added to the physical world.

Robert Adams 5f71ee57c4 BulletSim: stop avatar from sliding VERY slowly after walking by
only zeroing the movement motor in the UpdateProperties routine.

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.
2012-12-24 20:16:10 -08:00
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.

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
