* Soliciting for comments on smoothness of physics objects for this build.teravus2012-10-032-8/+46
| | | | | This introduces expected contact point hints to the ODE Collider to better determine when to throttle updates as excessive. This /should/ smooth physics objects out again, however, I cannot know every configuration of OpenSimulator, so I'm requesting that testers please examine this change on their build. Thanks!
* I propose that 0.5m/step change for linear velocity is too big of a change ↵teravus2012-10-031-1/+15
| | | | to control the reporting of a new angular velocity. I think that this could be here for one of two reasons, 1. vehicles and llMoveToTarget with axis lock, or 2. To attempt to make things look more stable in the physics scene then they really are, however, this also really affects the angular velocity reporting negatively causing things to spin wildly and jump back into place repeatedly. To compromise, if the prim is a vehicle or is being used as a motor target, the original functionality is still applied. If that's not the case, angular velocity is reported with a linear velocity of 0.02m/step. To be clear on the effect of the physical world... When you push things, there's still a lag time where you walk into the object but once the object is in motion, it begins to move as you would expect so results in slightly more realistic motion.

* BulletSim: remember to release the physical body and shape when a prim is ↵Robert Adams2012-09-282-16/+16

* BulletSim: add separate runtime and taint-time linkset children lists to ↵Robert Adams2012-09-273-80/+93

* BulletSim: rename some constraint variables to be consistant with other name ↵Robert Adams2012-09-277-116/+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.

* BulletSim: Fix linkset crash. Caused by the different body and shapeRobert Adams2012-09-279-94/+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.
* BulletSim: Terrain sets proper collision flags on creation.Robert Adams2012-09-274-52/+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().
* BulletSim: btGhostObjects working to make 'volume detect' work.Robert Adams2012-09-277-191/+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.
* BulletSim: renamed members of BulletShape, BulletSim and BulletBodyRobert Adams2012-09-2711-270/+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.

* BulletSim: Convert BSCharacter to use common BSPhysObject code and variables.Robert Adams2012-09-275-117/+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).
* BulletSim: move a bunch of common logic out of BSPrim and BSCharacterRobert Adams2012-09-277-416/+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'.

* BulletSim: Way too many changes in one commit.Robert Adams2012-09-159-286/+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.
* BulletSim: Add Bullet body and shape to BSPhysObject and renameRobert Adams2012-09-076-62/+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.

* BulletSim: PhysicsActorType() now returns the correct value rather than ↵Robert Adams2012-09-072-2/+3

* BulletSim: Modify collision flag calls to return the current flags.Robert Adams2012-09-072-7/+18
| | | | | | Track current collision flags in BSPrim. Add BulletSimAPI calls for saving and restoring rigidBodies using construction information structure.
* BulletSim: Update BulletSimAPI to match the DLL interface.Robert Adams2012-08-314-137/+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.
* BulletSim: clean up some variable naming for consistancy.Robert Adams2012-08-314-102/+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.

* BulletSim: Changes to terrain storage and management so mega-regions work.Robert Adams2012-08-318-185/+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.

* BulletSim: add parameters and functionality to specify the meshRobert Adams2012-08-173-48/+34
