Robert Adams 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.

Robert Adams 126eae7100 BulletSim: Add Bullet body and shape to BSPhysObject and rename
'Body' to 'BSBody' for disambiguation when reading code.
Complete the API2 interface so nearly all methods on bullet
    classes are available to the managed code. The efficient
    single call simulation step is kept in place while all
    other creation/destruction/parameterization can be done
    in the managed code.

Robert Adams 76dc29dc37 BulletSim: Modify collision flag calls to return the current flags.
Track current collision flags in BSPrim.
Add BulletSimAPI calls for saving and restoring rigidBodies using
    construction information structure.

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.

Robert Adams ae852bb873 BulletSim: clean up some variable naming for consistancy.
Update DLL API for new terrain and shape/body pattern methods.
Terrain creation and modification uses new shape/body pattern.
Move debug logging callback set to initialization call so logging
   is per physics engine.

Robert Adams 7c140570db BulletSim: Changes to terrain storage and management so mega-regions work.
Moved all terrain code out of BSScene and into new BSTerrainManager.
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.
    The unused code has not yet been removed from either place. Soon.
Moved checks for avatar above ground and in bounds into BSCharacter.
2012-08-31 11:41:18 -07:00
Robert Adams 0376b8ddbc BulletSim: add new interface for mesh, hull and terrain creation that will move nearly all of the logic into the C# code. 2012-08-31 11:41:07 -07:00
Robert Adams dd10cf01e7 BulletSim: add hinge constraint.
Update BulletSimAPI with new constraint related function calls.
Reorganize locking in BS6DofConstraint.
Update BS6DofConstraint to do constraint reset correctly.
Add new 'midpoint' construction of 6Dof constraint.

Robert Adams 0c7ce4fc98 BulletSim: many, many detailed logging messages for physical linkset
debugging.
Linkset bugs fixed where accounting of children would get lost.
Moved scene based vehicle tracking logic from prim to the scene.
Added GetCollisionFlags2 method to BulletSimAPI.
Updated DLLs and SOs.
2012-08-10 16:22:44 -07:00
Robert Adams 38e79b80a8 BulletSim: separate out the constraints by type. The linksets use
6dof constraint but eventually others will be exposed so future
features can use all the Bullet capabilities.
Force children to generate a position update when unlinked.
2012-08-09 15:01:05 -07:00
Robert Adams 19417fca41 BulletSim: Added avatar capsule scaling for size of avatar.
This also fixes computation of avatar mass.
Added parameter MaxPersistantManifoldPoolSize.
Fixed a parameter setting bug which caused crashes of there were
  more than 400 or so physical objects. I tested up to 5000.
Updated BulletSim DLLs and SOs.
2012-08-07 17:15:06 -07:00
Robert Adams e7ad6ed3a3 BulletSim: pass collision subscription information to the C++ code so collisions on objects that don't care are not reported up. 2012-08-03 15:09:56 -07:00
Robert Adams ea36d4a4cf BulletSim: Add AddObjectForce to BulletSim API.
Add interface 2 enhancements to BSCharacter.
Modify AddForce and SetForce to use the new Bullet interface.
More DetailLog statements for character.

Robert Adams e38d26a2dc BulletSim: change boolean parameters in the shape data from int's to float's to be consistant with parameter data structure 2012-07-31 16:23:48 -07:00
Robert Adams 50dbb9ffe4 BulletSim: add parameters and API calls for setting ERP and CFM.
Set ERP and CFM in linkset constraints.
Reorder rebuilding of object bodies so they are not rebuilt everytime
   something is linked and unlinked.
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

2012-07-23 16:32:30 -07:00
Robert Adams ca3b6b1f90 BulletSim: more detail logging for vehicle and general physics debugging.
Physical linksets are fully functional.
Tweeking of the vehicle code to make it semi-work.
Utilize the new API2 for some setting operations.
Add GetOrientation() API call for proper reporting of children of linksets.
Changes the interface between C# and C++ code so old DLLs won't work!
