15360cbb6b BulletSim: add adjustment for avatar capsule height scaling. Makes 
avatar standing on ground view better and enables tuning.

45f37e11ad BulletSim: use heightmap terrain when using BulletXNA. 
Output messages on features disabled when using BulletXNA.

a42bb799cc BulletSim: fix CPU loop that occurs when any 'degenerate' sculptie 
is in a region. This fixes the high CPU usage for regions with nothing
else going on.

ddd97cb78e BulletSim: normalize quaternian rotations when building compound linksets. 
Attempt to fix vehicles being twisted off the ground when they go physical.

84118c5735 BulletSim: properly free references to simple convex hull shapes. Didn't 
loose memory since shapes are shared but did mess up usage accounting.

93e1986d69 BulletSim: apply linear and angular friction in vehicle coordinates 
and not world coordinates.

045aaa838a BulletSim: remove friction calcuation from BSMotor and move linear and 
angular friction computation into linear and angular movement code.
The friction wasn't being applied properly. This will make it so vehicles
don't drift as much and the drift is tunable by changing the friction
timescales.

46ae84cfba BulletSim: fix error messages created while an avatar has no initial 
collisions. Usually happens when logging in an avatar that had been
previously flying. Uninitialized variable.

d322625f90 BulletSim: Add non-static BSShape.GetReference for getting another reference 
to an existing shape instance.
BSShapeNative rebuilds shape for all references.
BSShapeCompound returns another reference copy if the compound shape
already exists (for linksets).

15a3f80e2e BulletSim: LinksetCompound work to disable collision for root and 
child prims so compound shape can do all collisions.
Don't try to build a compound linkset for non-physical linksets.
Remove and replace root body when compound shape is added so collision
cache is rebuilt.

e5582939fd BulletSim: massive refactor of shape classes. Removed shape specific code from BSShapeCollection. Using BSShape* classes to hold references to shape. Simplified shape dependency callbacks. Remove 'PreferredShape' methods and have each class specify shape type. Disable compound shape linkset for a later commit that will simplify linkset implementation. 2013-04-29 07:38:40 -07:00

different physical mesh representations (simplified convex meshes)
and avatar mesh.

e324f6f3f0 BulletSim: update DLLs and SOs to they have no dependencies on newer 
glibc (2.14) since that is not yet in some Linux distributions.
Add unmanaged API calls and code for creating single convex hull shapes.

522ab85045 BulletSim: improve avatar stair walking up. Add more parameters to control force 
of both position change and up force that move avatars over barrier.
Default parameters are for steps up to 0.5m in height.

e1ac683154 BulletSim: fix crash when deleting llVolumeDetect enabled objects. Bullet's check for an object being linked into the world does not work for Bullet's ghost objects so BulletSim was deleting the object while it was still linked into the physical world structures. 2013-04-22 16:50:06 -07:00

or objects while still allowing an avatar to be moved if standing
on a moving object.

6a9630d2bd BulletSim: fix race condition when creating very large mega-regions. 
The symptom was exceptions while creating physical terrain.
Reduce default terrain mesh magnification to 2 from 3 because the
higher resolution uses a lot of memory and doesn't solve the terrain
smoothness for vehicles.
Added comments here and there and improved some debugging log messages.
