Robert Adams 1b203601f4 BulletSim: include the linkage to the layered prim implementation. Separate layers for physical (vs simulator) location displacement and linksets. 2013-02-08 16:29:29 -08:00
Robert Adams 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.
2013-02-01 11:52:27 -08:00
Robert Adams 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.

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.

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 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 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.
2013-01-15 21:08:46 -08:00
Robert Adams 61ff79587b BulletSim: add debugging messages to know when assets for physical
objects have been fetched.
Update TODO list with more work.
2013-01-15 21:08:46 -08:00
Robert Adams 181d4c6fcb BulletSim: temporarily disable banking and direction deflection
because the computations are wrong.
Add VehicleTorqueImpulse routines.
2013-01-15 02:58:14 -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 c2a7af18b6 BulletSim: nearly complete in conversion from BulletSimAPI to BSAPITemplate. Only initialization and debug fuctions left. 2012-12-31 19:57:23 -08:00
Robert Adams 5379d6d112 BulletSim: remove all the debug printing of pointer formatting (.ToString(X)) and replace it with a method on BulletBody, BulletShape, ... 2012-12-31 19:57:22 -08:00
Robert Adams 9218748321 BulletSim: another round of conversion: dynamics world and collision object functions. 2012-12-31 19:57:22 -08:00
Robert Adams 48f718f39f BulletSim: first round of conversion from direct BulletSimAPI interfacing by BulletSim core to using the BulletSimAPITemplate. Physical object creation and destruction first. 2012-12-31 19:57:21 -08:00
Robert Adams e57c0e6731 BulletSim: fix buoyancy so it's properly set by a script when an
object is selected.
Update TODO list.
2012-12-27 22:12:26 -08:00
Robert Adams 7230990679 BulletSim: fix odd code that wasn't really recomputing the mass of a
rebuilt linkset. I was burnt by making get/set methods with side
effects. I should know better.
2012-12-27 22:12:26 -08:00
Robert Adams 80cee1b85a BulletSim: Fix single physical prim reporting its mass as zero.
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.

Robert Adams 11532a4390 BulletSim: fix vehicles going underground when unsat. Problem was that, when doing unsit, the order of operations on the prims and the vehicle is very chaotic and not in a good order so the root prim was being left physical and thus it fell for a bit. Also changed default of velocity scaling to be closer to the movement standard. 2012-12-17 13:22:04 -08:00
Robert Adams 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
Robert Adams ace1f1e931 BulletSim: rip out old code for linkset child position fetching. BulletSim doesn't need to do that bookkeeping because SOG/SOP already does it. 2012-12-16 21:19:10 -08:00
Robert Adams 31d3952477 BulletSim: fix problem with continuious rebuilding of physical linksets. This caused movement problems and large prim vehicles to take up a LOT of simulation time. 2012-12-13 16:32:19 -08:00
Robert Adams 9e0dd9952b BulletSim: remove extra linkset rebuilds. 2012-12-13 16:32:00 -08:00
Robert Adams ebf30e7ba6 BulletSim: set mass for single prim linksets when going physical. This fixes single prim vehicles not working (the surf board now zooms). 2012-12-11 00:02:20 -08:00
Robert Adams 9df85eadf4 BulletSim: Fix crash on the destruction of physical linksets.
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.

Robert Adams a19896cc56 BulletSim: some comments about rebuilding linksets (having to recompute and restore a child's position in the world based on its position in the moved linkset). 2012-12-09 22:32:46 -08:00
Robert Adams 04e64d73df BulletSim: set material properties for static objects. Move Linkset.MakeStatic() after call to ForceActivationState2() since linkset might change activation state. Make BSPrim.CreateGeomAndObject public as linkset rebuilding might need access to it. Only rebuild prim if selection state is actually changes -- OpenSimulator calls PhysObject.Selected() multiple times whenever a prim is selected or deselected. 2012-12-08 09:14:40 -08:00
Robert Adams addb791f3d BulletSim: update comments and add more to TODO list. 2012-12-08 09:14:28 -08:00
Melanie 3b2caa63b0 Rename BulletSim's PhysicsShapeType to BSPhysicsShapeType because it
conflicts with PhysicsShape type defined in later libOMV
2012-11-22 14:45:41 +00:00
Robert Adams d6db0d5740 BulletSim: uplevel PhysicsShapeType out of ShapeData structure (since it is getting simplified out of existance someday) and update all the references to that enum. 2012-11-21 16:42:50 -08:00
Robert Adams f70a3099b5 BulletSim: recalculate the compound shape bounding box when built. 2012-11-06 18:16:12 -08:00
Robert Adams 79f7c466a1 BulletSim: fix compound linkset crash by not freeing shape of child prims.
Remove all compilation warnings (mostly 'protected' in sealed classes.)
Add the dynamicAabbEnable parameter to creation of compound shapes.
2012-11-03 21:16:02 -07:00
Robert Adams 894bb4893b BulletSim: search the mesh and hull lists to find shapes if type is not known. This makes sure the correct accounting is done for the particular shape. 2012-11-03 21:15:54 -07:00
Robert Adams 498ea76e63 BulletSim: Move construction of compound linkset from ShapeCollection
into LinksetCompound where it should be.
Create meshes for native shapes when part of a compound linkset because
    scale is currently per object and not per collision shape.
Don't schedule a LinksetCompound refresh if just changing properties.
2012-11-03 21:15:46 -07:00
Robert Adams b0eccd5044 BulletSim: debugging of compound shape implementation of linksets.
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.
2012-11-03 21:15:30 -07:00
Robert Adams 39c02dcc8c BulletSim: Remove use of shapeData in ShapeCollection and rely on the available BSPhysObject varaiables. Fix line endings in BSLinksetCompound. 2012-11-03 21:15:14 -07:00
Robert Adams 364a7c3088 BulletSim: rename BSBody and BSShape to PhysBody and PhysShape. Add skeleton of BSLinksetCompound. 2012-11-03 21:15:06 -07:00
