Robert Adams ad1787770e BulletSim: rename variable 'PhysicsScene' to be either 'PhysScene' or 'm_physicsScene' to match coding conventions and reduce confusion. 2013-04-29 07:38:55 -07:00
Robert Adams 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
Robert Adams 522ab85045 BulletSim: improve avatar stair walking up. Add more parameters to control force

2013-01-31 15:56:10 -08:00
Robert Adams 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.
Comments and updating of TODO list.
2013-01-31 15:56:02 -08:00
Robert Adams a61ecee227 BulletSim: fix physics repositioning when under ground to only happen
for physical objects. Non-physical objects can go anywhere they want.

Robert Adams c44a8e9f92 BulletSim: finish the post step event for physical object actions. Modify vehicle to use post step event for logging. 2013-01-27 12:50:04 -08:00
Robert Adams 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.
2013-01-24 14:35:23 -08:00
Robert Adams 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.

Robert Adams c1371ab786 BulletSim: working on COM 2013-01-23 14:25:06 -08:00
Robert Adams a0d460e6bf BulletSim: remove the unused RestoreBodyDependencies used by linksets
and vehicles and clean up code by removing their kludgyness.
2013-01-23 14:24:42 -08:00
Robert Adams 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).
2013-01-21 23:43:24 -08:00
Robert Adams 471c477863 BulletSim: allow changing position and rotation of a child of a linkset
without rebuilding the whole compound shape. Should make vehicles move
smoother.
2013-01-21 15:58:22 -08:00
Robert Adams 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.
2013-01-20 23:09:54 -08:00
Robert Adams 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.
2013-01-20 23:09:53 -08:00
Robert Adams 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.
2013-01-18 11:37:36 -08:00
Robert Adams 75f710f1e7 BulletSim: Add one function that all actors who act on the physical
can use to know if the object is currently active.
Code cleaning including use of Util.ClampV function.
2013-01-17 14:47:35 -08:00
Robert Adams 4e1ca890c2 BulletSim: fix not moving physical objects below terrain to over terrain.
Add locking on register prestep action list preventing potential race conditions.
Little comment and formatting changes.
2013-01-14 15:46:46 -08:00
Robert Adams 8bf0a9f85d BulletSim: disable center-of-mass computation for linksets until debugged. Move physical prim above ground if it is underground. Previously tried to correct by applying and up force but the prim would never go through the ground. 2013-01-14 07:50:58 -08:00
Robert Adams 459fcd81c9 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.
2013-01-11 16:47:53 -08:00
Robert Adams 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. 2013-01-11 16:47:20 -08:00
Robert Adams 98168edc29 BulletSim: remove double application of buoyancy. Centralize computation of buoyancy. Add motor angular debugging controls. 2013-01-11 16:46:38 -08:00
Robert Adams b592ec265b BulletSim: fix the 'No recognised physics mesh found ...' error spew by remembering that the last asset fetch failed until the simulator resets the shape parameters. 2013-01-11 16:44:34 -08:00
Robert Adams 8452c0a870 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.
2013-01-07 16:05:02 -08:00
Robert Adams 48cfc6d089 BulletSim: implement llMoveToTarget by adding PIDActive, etc.
Implementation of non-vehicle hover but haven't tested it a lot.
Update TODO list.
