Add and remove some detailed logging statements.
2012-09-27 22:01:26 -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 6632eb7c05 BulletSim: Remove calculation and passing of unused collied object type.
Fix collision code to properly sense mega-region children regions as terrain.
When setting an object physical, reset all the physical properties (friction, ...).

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 189f51233e BulletSim: PhysicsActorType() now returns the correct value rather than 'unknown'. 2012-09-07 16:05:16 -07:00
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.
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.
2012-08-31 11:41:28 -07:00
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 7b6987ce83 BulletSim: unify physical objects under BSPhysObjects. Now BSScene and BSLinkset only know of BSPhysObject's and there is only one list to search in BSScene. 2012-08-31 11:41:12 -07:00
Robert Adams 03d76e9403 BulletSim: restore most of the Detail logging statements. Will have
no effect on non-logging running.
Capture region name that is passed to the physics engine and use
    it for detail logging file name prefix.
Fix problem with avatars dropping when flying across region boundries.

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.
