BulletSim: move collision processing for linksets from BSPrimLinkable
...
into the linkset implementation classes.
Add HasSomeCollision attribute that remembers of any component of
a linkset has a collision.
Update vehicle code (BSDynamic) to use the HasSomeCollision in place of
IsColliding to make constraint based linksets properly notice the ground.
Add linkset functions to change physical attributes of all the members
of a linkset.

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.

BulletSim: move center of gravity of linkset to its geometric center.
...
Necessitated allowing simulator and physical position of a body to
get out of sync since Bullet assumes that <0,0,0> is the center of mass.
Update DLLs and SOs for the UpdateChildTransform so positions of
individual prim in a linkset can be implemented.

93adc4cb66
BulletSim: Add IsSelected attribute to physical objects. Have vehicles check to see if physical before trying to step. Replace vehicle gravity application. Previously relying on Bullet to apply gravity but since vehicles over-ride the velocity calculation, gravity never had a chance to accelerate the body down. Added AddForceImpulse as well as AddForce for those who need to apply immediate velocity updates. Use the impulse to apply the linear motion.

BulletSim: add function to push avatar up when hitting stairs.
...
It looks like BulletSim and ODE rely on penetration correction to cause
the avatar to move up and thus allowing walking up stairs. Object
penetration was minimized for walking and flying (so one doesn't go
through walls) and this stopped stairs from working. This commit
introduces avatar movement code to check for collisions at the
feet while walking and attempts to raise the avatar for the steps.
Not yet perfect but movement is better.

BulletSim: Fix llApplyImpulse so it works after the first impulse. The problem was Bullet deactivating the object between the pushes (when, as far as the physics engine is concerned, it isn't moving).

3d659fe97d
BulletSim: add BSPhysObject code to manage registrations of preStep events. Use same to implement setForce and setTorque so the values are restored at the beginning of each step (since Bullet zeros forces applied last step). Simplify implementation of AddForce and AddTorque by relying on the addition of forces in Bullet.
2012-12-21 17:27:53 -08:00
2b8efa24dd
BulletSim: add parameter to UpdateProperties call into the linkset so changes from the physics engine can be differentiated from changes made by the user. This eliminates a linkset rebuild loop. Also add logic to not rebuild or freak out when the object/linkset crosses a terrain boundry.
2012-12-16 21:19:13 -08:00

BulletSim: fix problem of avatar's floating off the ground after unsitting. Reworked size/scale logic so physical scale is kept in Bullet and physObject scale is the preferred size -- usually same as size but avatars are computed differently.

While fixing the above, add methods to physical body and shape pointer

Fix problem with physical linksets failing after a few sits and
unsits by properly restoring child prom positions for compound
linksets after multiple selection and deselections.
