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.

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.

80b1e32bfa BulletSim: Tweeks to vehicle motion.
Pass through old angular velocity making for smoother transitions.
Remove some old kludges for angular motion (damping and rotvel suppression).

471c477863 BulletSim: allow changing position and rotation of a child of a linkset
without rebuilding the whole compound shape. Should make vehicles move
smoother.

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

c6b6c94ccb BulletSim: reduce jitter in avatar velocity when walking or flying.
OpenSimulator is VERY sensitive to changes in avatar velocity and
will send an avatar update message when velocity changes more than
0.001m/s. This significantly reduces the number of avatar update messages by
smoothing the avatar velocity returned by Bullet.

482c7b5368 BulletSim: add logic to turn off pre-step actions when object goes
non-active. This turns off 'setForce', 'setTorque' and 'moveToTarget'
when the object is selected or made non-physical.

5d098d8f17 BulletSim: don't modify angular parameters when doing LIMIT_MOTOR_UP.
It was a dumb idea to try and do a nose over feature for jumping cars anyway.
Add better logging of native shape creation/reuse so can  tell the difference.
