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.

Robert Adams 498ea76e63 BulletSim: Move construction of compound linkset from ShapeCollection
into LinksetCompound where it should be.

    scale is currently per object and not per collision shape.
Don't schedule a LinksetCompound refresh if just changing properties.

Robert Adams 1dc23b2b97 BulletSim: parameterize selection of linkset implementation 2012-11-03 21:15:39 -07:00
Robert Adams b0eccd5044 BulletSim: debugging of compound shape implementation of linksets.
Add compound shape creation and freeing in shape manager.
Add optional taint-time execution method and update code to use it.
Add API2 linkage for more compound shape methods (get num, get/remove by index, ...)
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.
2012-11-03 21:15:30 -07:00
Robert Adams 364a7c3088 BulletSim: rename BSBody and BSShape to PhysBody and PhysShape. Add skeleton of BSLinksetCompound. 2012-11-03 21:15:06 -07:00

Robert Adams f422b9b388 BulletSim: reorder avatar collision checking to eliminate double collision_end.
Various tweekings to avatar shape/mass/inertia/etc.

2012-10-19 10:51:58 -07:00

Robert Adams a86fedd25f BulletSim: normalize physics FPS to 45. 2012-10-11 14:01:22 -07:00
Robert Adams 919569f6ec BulletSim: Change defaults for constraint CFM and ERP to make large linksets more rigid. Remove mass calculation for terrain (it should stay a static object). 2012-10-11 14:01:14 -07:00
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.

    does not change.

    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 210f227fe6 BulletSim: Make parameter value defaults match what should be the default and what is in OpenSimDefaults.ini. Comment and debug printout changes. 2012-10-02 11:14:15 -07:00

    to vehicle motion.
2012-09-27 22:01:52 -07:00

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

2012-09-27 22:01:21 -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

Correct uses of timestep in timescale calculations for vehicles.
Reorganize code/logic for making objects static and dynamic for readability
    and use of API2.
Changed most calls in BSPrim to use API2 calls (the new way).

    to the simulator for every avatar. Reduces overhead.
Objects added to collision list only if they are processing collisions.
    Reduces overhead especially for large numbers of avatars.
Generalize call for water height to GetWaterHeightAtXYZ().
Catch and correct exception getting terrain height when out of bounds.

Robert Adams ffdc798720 BulletSim: Update BulletSimAPI to match the DLL interface.
Major rework of terrain management which finally makes mega-regions work.
Update heightmap of terrain by rebuilding the terrain's body and shape.
    There is a problem with just replacing the shape so this workaround
    will do for the moment but it will need to be resolved for
    mesh and hull switching.
2012-08-31 11:41:33 -07:00
Robert Adams ae852bb873 BulletSim: clean up some variable naming for consistancy.

2012-08-31 11:41:18 -07:00

Robert Adams 03d76e9403 BulletSim: restore most of the Detail logging statements. Will have

    it for detail logging file name prefix.
Fix problem with avatars dropping when flying across region boundries.

2012-07-31 09:23:05 -07:00
Robert Adams 7d30637d51 BulletSim: refactor all the linkset logic out of the prim class
and into its own class. The BulletSim data structures track
individual prims as linksets of 1 so most of the prim code is not
different between a linked and unlinked object.
2012-07-26 16:05:57 -07:00
Robert Adams d7add2940a BulletSim: add parameters for setting linkset constraint factors 2012-07-25 16:31:08 -07:00

Tweeking of the vehicle code to make it semi-work.

with an ini configuration parameter.
Correct computation of relative offsets of children in a linkset.
Remove a prim from any link relationship before deleting it.
Minor code flow cleanups.
2012-07-20 14:02:22 -07:00
Robert Adams e4a6611865 Clean up collision reporting code so they are properly passed to
the simulator in batches.
More comments.
2012-07-06 15:09:19 -07:00
Robert Adams 872d513daa BulletSim: make avatar animations update properly.
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.
