Robert Adams cbc7e7bf85 BulletSim: Make avatar capsule so it is not circular.
Simple attempt to make avatars better shaped.
Replace parameter 'avatarCapsuleRadius' with 'avatarCapsuleWidth'
and 'avatarCapsuleDepth'.
More tweeking to avatar height calculation. A little better but
short avatar's feet are above the terrain and tall avatar's feet
are a little below the ground.

2012-11-03 21:16:02 -07:00
Robert Adams b0eccd5044 BulletSim: debugging of compound shape implementation of linksets.
Add compound shape creation and freeing in shape manager.

Modify perferred shape return so linkset children can have differet shapes than root.
Add Position and Orientation calls to linksets so children can be moved around by
    the linkset by its own calculation. Allows for very general linkset implementations.

Remove some experimental changes.
2012-11-03 21:14:58 -07:00
Robert Adams 52be581f71 BulletSim: remove center-of-mass setting for linksets because it causes the constraint calculation to pull the objects together. 2012-11-03 21:14:49 -07:00
Robert Adams e20bad12cc BulletSim: centralize mass/inertia computation with UpdatePhysicalMassProperties() function. Didn't add setMassRaw because assignment with side effect is dirty. 2012-11-03 21:13:35 -07:00
Robert Adams 8fa83cf430 BulletSim: Add activations after vehicle properties change. Problem was the vehicle was going to sleep while waiting for commands. Make AddAngularForce work the same way as AddForce -- accumulates values and pushes them once into Bullet. 2012-11-03 21:13:03 -07:00
Robert Adams 804b332d45 BulletSim: Add banking and other new code to vechile dynamics. Add third party license and contributor in for for Aurora-Sim project for physics code. 2012-11-03 21:12:46 -07:00

Add capsule shape to BSShapeCollection().
Remember last updated values so inter frame diffs can be computed.
Parameterize avatarStandingFriction and reduce to 10 from 999.
    The latter high value made avatars very hard to push.

Robert Adams a791620622 BulletSim: cosmetic changes (comments and renaming). Give mass to terrain to improve interactions. 2012-10-11 14:01:10 -07:00
Robert Adams 68698975f1 BulletSim: Add Force* operations to objects to allow direct push to engine.
Update BSDynamics to use same (don't want to delay updates til next taint-time.
Suppress queuing a taint update for position and orientation calls if value
    does not change.
Move Bullet timing statistics call from C# back to C++ code.
Throttle taints per simulation step and add parameter to set.
By default, don't create hulls for physical objects. Add a
    parameter to turn on and off.
2012-10-11 14:01:07 -07:00
Robert Adams 87825b0abe BulletSim: Fix crash when linking large physical linksets.
Properly remove and restore linkage constraints when upgrading
    a prim's mesh to a hull.
Lots more debug logging.
Definitions and use of Bullet structure dumping.
Centralize detail logging so a Flush() can be added for debugging.
2012-10-11 14:01:03 -07:00
Robert Adams ce47d0c454 BulletSim: Add ForcePosition and ForceOrientation to BSPhysObject and to its children of BSPrim and BSCharacter. 2012-10-02 11:14:09 -07:00
Robert Adams 33617e09a1 BulletSim: impliment FloatOnWater OS function. 2012-10-02 11:13:32 -07:00
Robert Adams 5221f2421e BulletSim: remove warnings for unused variables. 2012-10-02 11:13:20 -07:00
Robert Adams 76e9cc41bd BulletSim: remember to release the physical body and shape when a prim is destroyed. This fixes many problems with physical linksets. 2012-09-28 12:34:50 -07:00
Robert Adams 6f89975526 BulletSim: add separate runtime and taint-time linkset children lists to keep the creation of constraints separate from runtime. 2012-09-27 22:02:13 -07:00
Robert Adams 74dea4cfd5 BulletSim: rename some constraint variables to be consistant with other name use.
Added callbacks for shape and body changes in GetBodyAndShape() so the linkset
    constraints can be picked up and restored. A better design might be to have
    a "prim shape changed" event. Think about that.
Added constraint types to general constraint class.
2012-09-27 22:02:08 -07:00
Robert Adams 7b65985047 BulletSim: remove the trailing spaces from lines to make git happier 2012-09-27 22:02:03 -07:00
Robert Adams 5781d4d52d BulletSim: remove the unused body management code from BSPrim. There is no going back now. 2012-09-27 22:01:57 -07:00
Robert Adams f82b903dee BulletSim: Fix linkset crash. Caused by the different body and shape
pointers at runtime and at taint-time. Now passes the body into the
    taint.
Vehicles zero inertia when active to eliminate Bullet's contribution
    to vehicle motion.
2012-09-27 22:01:52 -07:00
Robert Adams 4589bc84a3 BulletSim: Terrain sets proper collision flags on creation.
Static objects are set to ISLAND_SLEEPING rather than DISABLE_SIMULATION.
    Might reconsider this and, alternatively, have dynamic objects force activation.
Clean up use of DetailLog().
2012-09-27 22:01:47 -07:00
Robert Adams 735d89e369 BulletSim: btGhostObjects working to make 'volume detect' work.
Rearrangement and cleanup of shape collection code. Much more readable.
Enabling and use of collision filters and masks.
Addition of ID to body creation BulletSimAPI calls so always set in
    shape for collision reporting.
Change default of ShouldSplitSimulationIslands and ShouldRandomizeSolverOrder
    from 'false' to 'true'. When 'false', this suppresses NO_CONTACT_RESPONSE
    which makes volume detect fail.
2012-09-27 22:01:42 -07:00
Robert Adams d016051fa0 BulletSim: renamed members of BulletShape, BulletSim and BulletBody
so the members case is consistant. Caused modifications everywhere.
New logic in BSShapeCollection to track use and sharing of shapes.
    I just reslized, though, that shapes cannot be shared because the
    shape's UserPointer is the localID of the prim and is required
    for tracking collisions. More changes coming.
Added DuplicateCollisionShape2() to API and changed BuildNativeShape2
    to take a ShapeData structure so don't have to pass so many parameters.
    This matches the latest version of BulletSim.dll.
Additions and removal of DetailLog() statements for debugging.
2012-09-27 22:01:37 -07:00

Eliminate some null exceptions created adding the above code.
Add and remove some detailed logging statements.
2012-09-27 22:01:26 -07:00
Robert Adams a27e4ce6cb BulletSim: add class and infrastructure for shape and object
tracking in the C# code. Needed for the changing body type
    (to and from GhostObjects) for volumeDetect.
2012-09-27 22:01:21 -07:00
Robert Adams 91efccabdc BulletSim: Convert BSCharacter to use common BSPhysObject code and variables.
Fix avatar height calculation to properly account for the capsule ends.
Rearrange some locking in TerrainManager to eliminate possible race conditions.
Move DetailLog() definition into common BSPhysObject class.
Some variable renaming to make usage clearer (refactor.rename makes this so easy).
2012-09-27 22:01:16 -07:00
Robert Adams ee7cda261c BulletSim: move a bunch of common logic out of BSPrim and BSCharacter
and into the parent class BSPhysObject.
Rework collision logic to enable extra collision after done colliding.
Rename 'Scene' to 'PhysicsScene' to differentiate it from the simulator 'Scene'.
2012-09-27 22:01:11 -07:00
Robert Adams c77be802d2 BulletSim: some debugging prints in BSPrim for tracking changes in linkset children. 2012-09-15 15:32:16 -07:00
