2012-09-28BulletSim: remember to release the physical body and shape when a prim is ↵Robert Adams2-16/+16
destroyed. This fixes many problems with physical linksets.
2012-09-27BulletSim: add separate runtime and taint-time linkset children lists to ↵Robert Adams3-80/+93
keep the creation of constraints separate from runtime.
2012-09-27BulletSim: rename some constraint variables to be consistant with other name ↵Robert Adams7-116/+231
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.
2012-09-27BulletSim: remove the trailing spaces from lines to make git happierRobert Adams10-276/+275
2012-09-27BulletSim: remove the unused body management code from BSPrim. There is no ↵Robert Adams1-374/+0
going back now.
2012-09-27BulletSim: Fix linkset crash. Caused by the different body and shapeRobert Adams9-94/+182
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.
2012-09-27BulletSim: Terrain sets proper collision flags on creation.Robert Adams4-52/+56
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().
2012-09-27BulletSim: btGhostObjects working to make 'volume detect' work.Robert Adams7-191/+265
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.
2012-09-27BulletSim: renamed members of BulletShape, BulletSim and BulletBodyRobert Adams11-270/+482
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.

2012-09-27BulletSim: complete code for managed code shape and body tracking. Not debugged.Robert Adams5-130/+675
Eliminate some null exceptions created adding the above code. Add and remove some detailed logging statements.
2012-09-27BulletSim: add class and infrastructure for shape and objectRobert Adams5-39/+192
tracking in the C# code. Needed for the changing body type (to and from GhostObjects) for volumeDetect.
2012-09-27BulletSim: Convert BSCharacter to use common BSPhysObject code and variables.Robert Adams5-117/+113
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).
2012-09-27BulletSim: move a bunch of common logic out of BSPrim and BSCharacterRobert Adams7-416/+361
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'.

2012-09-15BulletSim: Remove calculation and passing of unused collied object type.Robert Adams4-28/+36
Fix collision code to properly sense mega-region children regions as terrain. When setting an object physical, reset all the physical properties (friction, ...).

2012-09-15BulletSim: Way too many changes in one commit.Robert Adams9-286/+351
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.
2012-09-07BulletSim: Add Bullet body and shape to BSPhysObject and renameRobert Adams6-62/+505
'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.
2012-09-07BulletSim: Add some comments (gasp) and log messages.Robert Adams4-4/+13
2012-09-07BulletSim: PhysicsActorType() now returns the correct value rather than ↵Robert Adams2-2/+3
'unknown'.
2012-09-07BulletSim: Modify collision flag calls to return the current flags.Robert Adams2-7/+18
Track current collision flags in BSPrim. Add BulletSimAPI calls for saving and restoring rigidBodies using construction information structure.
2012-08-31BulletSim: Update BulletSimAPI to match the DLL interface.Robert Adams4-137/+231
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.
2012-08-31BulletSim: clean up some variable naming for consistancy.Robert Adams4-102/+183
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.
2012-08-31BulletSim: fix line endings.Robert Adams1-22/+22
2012-08-31BulletSim: Changes to terrain storage and management so mega-regions work.Robert Adams8-185/+597
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.
2012-08-31BulletSim: unify physical objects under BSPhysObjects. Now BSScene and ↵Robert Adams5-160/+200
BSLinkset only know of BSPhysObject's and there is only one list to search in BSScene.
2012-08-31BulletSim: add new interface for mesh, hull and terrain creation that will ↵Robert Adams1-7/+20
move nearly all of the logic into the C# code.
2012-08-17BulletSim: Properly regenerate hulls when objects made physical.Robert Adams1-9/+25
This fixes the problem of non-base shapes (cubes and spheres) falling through the terrain.
2012-08-17BulletSim: restore most of the Detail logging statements. Will haveRobert Adams4-40/+51
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.
2012-08-17BulletSim: add parameters and functionality to specify the meshRobert Adams3-48/+34
level of detail for large meshes. Remove parameter and code for DetailLog (conditional logging into regular log file).

2012-08-17BulletSim: in BSDynamics, merge 'flags' and 'hoverFlags' as they are defined ↵Robert Adams1-158/+20
for the same bits and it makes the code less complicated.
2012-08-15BulletSim: make it so objects in a linkset do not generate collisions with ↵Robert Adams3-2/+27
each other.
2012-08-15BulletSim: add hinge constraint.Robert Adams3-6/+126
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.
2012-08-15BulletSim: add locking to constraintCollection and rename some of the public ↵Robert Adams2-147/+197
method variables to reduce confusion between a physics scene and the real scene.
2012-08-15BulletSim: clean up detail logging by adding many more debug log statements ↵Robert Adams5-34/+44
and then commenting out most of the additions.
2012-08-15BulletSim: don't recreate mesh unless it needs it when rebuilding the hull. ↵Robert Adams1-15/+15
Make sure the collisionCollection is reallocated each tick to fix race condition of it being cleared while still in use.
2012-08-15BulletSim: fix problem of a null reference exception on shutdown if there ↵Robert Adams1-12/+13
were linksets in the region.
