to get ready for...
Start creation of BulletAPITemplate. This defines the abstract interface
functions. Following commits will move over to the new interface.
This will enable switching between the managed and unmanaged version of
Bullet.
While fixing the above, add methods to physical body and shape pointer
wrapper so routines won't have to know that IntPtr.Zero means no
physical instance.
Fix problem with physical linksets failing after a few sits and
unsits by properly restoring child prom positions for compound
linksets after multiple selection and deselections.
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.
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.
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.
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.
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.
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.
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.
