did the right thing for stopping (speed reducing to zero), it prevented
movement from starting (speed increasing from zero). Will revisit
when the generalize PID motor is debugged.
Looks like the viewer bombards the server with avatar orientation
information (we're talking several hundred a second) when the avatar
is being turned or when walking. This change just reduces the number
of 'set' calls into unmanaged code.
asymmetrical avatar capsule work now that rotation is being passed
from the simulator. Turns out the Bullet capsule is just not very
functional: it doesn't scale properly, the implementation only half
does asymmetry and, in general, is hard to work with.
Avatar shape is about what it was before these changes.
Added initial data structures for avatar shape mesh.
Properly return root mass as mass of just the root prim rather
than the mass of the linkset. SOG has the logic to add the masses
together to get the linkset mass.
Update TODO list.
for the operation of BulletSim and those defintiions/structures defined
so they can be used in the unmanaged world.
Consolidate setting of collision flags so implementation is not scattered.
While fixing the above, add methods to physical body and shape pointer
wrapper so routines won't have to know that IntPtr.Zero means no
physical instance.
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.
static objects by more restrictive selection of objects that collide
with static objects.
Rename collision mask fuctions from 'filter' to 'group' so it is clear
what is being set.
Rename BulletSimAPI.SetCollisionFilterMask() to SetCollisionGroupMask to match above.
Restore passing of time step to linear and angular motion component routines.
Use buffering vehicle physical parameter get/set routines consistantly.
Make range enforcement clearer by using ClampInRange() function for parameter setting.
Remove commented out experimental vehicle calculations.
Simple attempt to make avatars better shaped.
Replace parameter 'avatarCapsuleRadius' with 'avatarCapsuleWidth'
and 'avatarCapsuleDepth'.
More tweeking to avatar height calculation. A little better but
short avatar's feet are above the terrain and tall avatar's feet
are a little below the ground.
Add compound shape creation and freeing in shape manager.
Add optional taint-time execution method and update code to use it.
Add API2 linkage for more compound shape methods (get num, get/remove by index, ...)
Modify perferred shape return so linkset children can have differet shapes than root.
Add Position and Orientation calls to linksets so children can be moved around by
the linkset by its own calculation. Allows for very general linkset implementations.
Various tweekings to avatar shape/mass/inertia/etc.
Remove change from avatar radius to diameter. But still the avatar sinks.
Collision_end now happens immediately rather than at the next subscription time.
Change character scaling to represent size of capsule (diameter rather than radius)
Modify create capsule call to pass radius and height.
Eliminate errors when calculating shape inertia (should have some type checking).
Add capsule shape to BSShapeCollection().
Remember last updated values so inter frame diffs can be computed.
Parameterize avatarStandingFriction and reduce to 10 from 999.
The latter high value made avatars very hard to push.
Set CCD parameters for prims and characters of specified.
Update BSDynamics to use same (don't want to delay updates til next taint-time.
Suppress queuing a taint update for position and orientation calls if value
does not change.
Move Bullet timing statistics call from C# back to C++ code.
Throttle taints per simulation step and add parameter to set.
By default, don't create hulls for physical objects. Add a
parameter to turn on and off.
