894bb4893b BulletSim: search the mesh and hull lists to find shapes if type is not known. This makes sure the correct accounting is done for the particular shape. 2012-11-03 21:15:54 -07:00

498ea76e63 BulletSim: Move construction of compound linkset from ShapeCollection
into LinksetCompound where it should be.
Create meshes for native shapes when part of a compound linkset because
    scale is currently per object and not per collision shape.
Don't schedule a LinksetCompound refresh if just changing properties.

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.

9568f24c26 BulletSim: add post taint taints and post step taints. The post taints operation is most useful and is used by linksets to build and rebuild only once before the simulation step. 2012-11-03 21:13:52 -07:00

f422b9b388 BulletSim: reorder avatar collision checking to eliminate double collision_end.
Various tweekings to avatar shape/mass/inertia/etc.
Remove change from avatar radius to diameter. But still the avatar sinks.
Collision_end now happens immediately rather than at the next subscription time.

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

    does not change.
Move Bullet timing statistics call from C# back to C++ code.

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.

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.

    to vehicle motion.

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.

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.

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'.

2c5ff93990 BulletSim: Way too many changes in one commit.
Many changes to BSDynamic for readability and commentary.
Linkset hacking for vehicles: don't over mass the root prim.
Add parameter for link constraint solver iterations.
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).
Avatars do not generate default Bullet collision events but do call up
    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.
Correct race condition in Terrain Manager where creation wasn't at taint-time.
Add API calls for constructing compound shapes.
Move NeedsMeshing() logic into object class.
Reorganize logic for object meshing to reduce rebuilding of meshs/hulls.

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.

ae852bb873 BulletSim: clean up some variable naming for consistancy.

Added logic to manage multiple terrains for mega-regions.
Added new functions to BulletSimAPI to match the library.
Moved all of the terrain creation and setup logic from C++ code to C# code.
