Bullet 2.81

taint-time specification to new AddForce().
|
|
more rigid. Remove mass calculation for terrain (it should stay a static object).
|
|
improve interactions.
|
|
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.
|
|
and what is in OpenSimDefaults.ini. Comment and debug printout changes.
|
|
children of BSPrim and BSCharacter.
|
|
type changed.
|
|
was using the child shape address at call time rather than the one created at taint time.
|
|
no lag between what the vehicle code sees and what the physics engine is using.

destroyed. This fixes many problems with physical linksets.
|
|
keep the creation of constraints separate from runtime.
|
|
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.
|
|
|
|
going back now.
|
|
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.
|
|
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().
|
|
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.

collision shape
|
|
Eliminate some null exceptions created adding the above code.
Add and remove some detailed logging statements.
|
|
tracking in the C# code. Needed for the changing body type
(to and from GhostObjects) for volumeDetect.
|
|
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).
|
|
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'.

setting. There is no reason these should be using the simulation time interval for parameter calculation.
|
|
Fix collision code to properly sense mega-region children regions as terrain.
When setting an object physical, reset all the physical properties (friction, ...).
|
|
center of mass
|
|
Reset center of mass on an object when going dynamic.
|

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.

'unknown'.
|
|
Track current collision flags in BSPrim.
Add BulletSimAPI calls for saving and restoring rigidBodies using
construction information structure.
|
|
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.
