Add compound shape creation and freeing in shape manager.
Add optional taint-time execution method and update code to use it.
Add API2 linkage for more compound shape methods (get num, get/remove by index, ...)
Modify perferred shape return so linkset children can have differet shapes than root.
Add Position and Orientation calls to linksets so children can be moved around by
the linkset by its own calculation. Allows for very general linkset implementations.
Various tweekings to avatar shape/mass/inertia/etc.
Remove change from avatar radius to diameter. But still the avatar sinks.
Collision_end now happens immediately rather than at the next subscription time.
Change character scaling to represent size of capsule (diameter rather than radius)
Modify create capsule call to pass radius and height.
Eliminate errors when calculating shape inertia (should have some type checking).
Add capsule shape to BSShapeCollection().
Remember last updated values so inter frame diffs can be computed.
Parameterize avatarStandingFriction and reduce to 10 from 999.
The latter high value made avatars very hard to push.
Set CCD parameters for prims and characters of specified.
Update BSDynamics to use same (don't want to delay updates til next taint-time.
Suppress queuing a taint update for position and orientation calls if value
does not change.
Move Bullet timing statistics call from C# back to C++ code.
Throttle taints per simulation step and add parameter to set.
By default, don't create hulls for physical objects. Add a
parameter to turn on and off.
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.
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.
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.
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.
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'.
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.
'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.
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.
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.
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.
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.
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.
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.
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.
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!
