3646361279 BulletSim: make removing zero width triangles from meshes optional 
and, for the moment, default to 'off'.

dce9e323f4 BulletSim: remove degenerate triangles from meshes. This fixes the 
invisible barriers in sculptie doorways (Mantis 6529).
Bump up level-of-detail for physical meshes to 32 (the max). This
fixes the invisible barriers that showed up in prim cut arches.
NOTE: the default LOD values are removed from OpenSimDefaults.ini.
   If you don't change your OpenSimDefaults.ini, you will continue
   to see the arch problem.

ad438ee59f BulletSim: rework some parameter setting implementation moving functionality that was in BSScene to BSParam. Remove unused parameters that were passed to the unmanaged code. Update DLLs and SOs for the new param block. 2013-02-05 16:56:23 -08:00

1f1da23097 Bump version and assembly version numbers from 0.7.5 to 0.7.6 
This is mostly Bluewall's work but I am also bumping the general version number
OpenSimulator 0.7.5 remains in the release candidate stage.
I'm doing this because master is significantly adding things that will not be in 0.7.5
This update should not cause issues with existing external binary DLLs because our DLLs do not have strong names
and so the exact version match requirement is not in force.

5bb85a14d4 BulletSim: fix problem where editting a physical linkset caused the 
child prim physical positions to get out of sync with the view.
More reliably compute the offset of children in a physical linkset.

75a05c16c5 BulletSim: fix crash caused when linksets were rebuilt. A problem added 
when individual child pos/rot changes were implementated a week or so ago.
Remove some passing of inTaintTime flag when it was never false.

ed71c939fc BulletSim: make sure vehicle physical properties are set when going 
physical by delaying setting until pre-step time. Change vehicle.Refresh()
to schedule the pre-step setting.

6a5d088197 BulletSim: reduce the force of gravity on ground vehicles when they 
are on the ground. Makes them a little more stable.

a2a32fc844 BulletSim: reduce the zeroing threshold for rotational velocity. 
Sometimes settling of a vehicle from gravity introduces small
velocities that need to be kept.

591faac3ac BulletSim: disable CCD (continuious collision detection) and 
contact processing threshold since the first didn't solve tunneling
problems but used resources and the latter caused instabilities.

2cf29c87bc BulletSim: zero motion on an object that we pop up because it is 
below terrain. If the position is being corrected because it is out
of bounds, all other movement rules are out the window.

d5b950633d * Added in the manifold point dept on collision desc. In BulletSim engine BulletXNA. 2013-01-24 07:36:24 -05:00
teravus
ba9d6b7337 * Repairs the Object updates, Collision updates, and Child Prim methods making the bulletXNA engine work again. 
* The only thing that had an issue was when creating a new RigidBody, BulletXNA didn't know the type SimMotionState and the upcast type is unknown in the constructor.   Therefore, I had to update the IMotionState with a new method 'SetBody'.    All of the duplicated type information has been removed and BulletXNA is not relying on any non-standard types external to the library.

a7b810ddee BulletSim: remove setting of vehicle InterpolationRotationalVelocity. 
This doesn't seem to help the vehicle stability.
Rename vehicle internal variables adding a "V" or "W" so it is clear
when coordinates are vehicle or world relative.

52b341e2e2 BulletSim: More aggressive as setting character velocity to zero 
when should be standing.
Modify angular force routines to be the same pattern as linear force routines.
BulletSim vehicle turning is scaled like SL and is DIFFERENT THAN ODE!!
Fix some bugs in BSMotor dealing with the motor going to zero.
Add a bunch of parameters:  MaxLinearVelocity, MaxAngularVelocity,
MaxAddForceMagnitude, VehicleMaxLinearVelocity, VehicleMaxAngularVelocity,
and most of the values are defaulted to values that are larger
than in SL.
Use the new parameters in BSPrim, BSCharacter and BSDynamic.

3b0df52d10 BulletSim: modify motors to return correction rather than current value 
to better use them for incremental updates.
Modify prim and character to use the new motors.
Simplify the vehicle linear movement code to just update the velocity
directly or the basic movement.

2c517d792f This updates prebuild to remove BulletSimN, implements the BulletSim API in BulletSPlugin using the BulletXNA Bullet physics engine. It also updates the BulletXNA library to be compatible with the changes. OpenSimDefaults has been updated to describe how to switch engines and terrain implementations. 2013-01-20 08:18:16 -05:00
