Robert Adams 0baa2590be BulletSim: check for completely degenerate meshes (ones with all
triangles having zero width) and output an error rather than
throwing and exception.
2013-02-06 15:52:28 -08:00
Robert Adams 67d92e4e16 BulletSim: remove an exception which occurs if a physics mesh
asset is not found.
2013-02-06 14:00:27 -08:00
Robert Adams 3646361279 BulletSim: make removing zero width triangles from meshes optional
and, for the moment, default to 'off'.
2013-02-05 17:19:55 -08:00
Robert Adams dce9e323f4 BulletSim: remove degenerate triangles from meshes. This fixes the
invisible barriers in sculptie doorways (Mantis 6529).
Bump up level-of-detail for physical meshes to 32 (the max). This
fixes the invisible barriers that showed up in prim cut arches.
NOTE: the default LOD values are removed from OpenSimDefaults.ini.
   If you don't change your OpenSimDefaults.ini, you will continue
   to see the arch problem.

Robert Adams 13233da66c BulletSim: add debugging looking for doorway sculpty problems 2013-02-05 16:56:28 -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.
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 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 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 2eba80a8cd BulletSim: fix problem where mesh shapes were physically just their bounding box and not the complete mesh. Fill mesh physical objects are back. 2013-01-04 17:06:52 -08:00
Robert Adams 9d840fd2ee BulletSim: move over and port the interface for BulletXNA.
Copied BulletSNPlugin.BulletSimAPI to a new
BulletSPlugin.BSAPIXNA.cs and then modifyed the latter to
comply with the BSAPITemplate definition. Not totally debugged
but the code is all there for an INI variable to select either
unmanaged C++ Bullet or the C# version of Bullet.
2013-01-01 17:27:33 -08:00
Robert Adams 04132d3af4 BulletSim: subclass Bullet[World|Body|Shape|Constraint] for unmanaged
to have pointers and managed to have objects.
Initial paste of XNA code. Commented out.
2013-01-01 17:27:32 -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 db6c0363f0 BulletSim: tweeking avatar capsule code in an attempt to have
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.
2012-12-29 08:03:57 -08:00
Robert Adams bbc5a5089f BulletSim: Rename some of the interface structures (BulletWorld, ...)
to get ready for...
Start creation of BulletAPITemplate. This defines the abstract interface
functions. Following commits will move over to the new interface.
This will enable switching between the managed and unmanaged version of
Bullet.

Robert Adams ae4d932e7f BulletSim: Move all the parameter variables, tables and get and fetch logic to a separate, static class for easier addition and to remove all that bulk from the BSScene class. 2012-12-21 13:35:44 -08:00
Robert Adams e1814aa827 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. 2012-12-12 16:51:43 -08:00
Robert Adams 8b861e880a BulletSim: add ini file and command line parameters to control
dumping of physical vehicle parameters (out of Bullet) on each
simulation step and to optionally scale vehicle angular velocity
by the time step. The latter looks to be part of a difference
between angular parameters for ODE and BulletSim. SL docs say
angular velocity is measured in radians/timeScale. Not sure if this
is different than what ODE does.
2012-12-11 00:13:13 -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.
2012-12-10 15:35:53 -08:00
Robert Adams 216c121935 BulletSim: fix small problem with setting size/scale of native shapes which caused the native shapes to be rebuilt when not necessary. 2012-12-08 09:14:34 -08:00
Robert Adams 18fe35906d BulletSim: add detail logging detail flag so I don't have to comment and uncomment the detail logging when changing the depth of logged info. 2012-12-06 09:30:57 -08:00
Robert Adams 0cd99c74a7 BulletSim: add expanded call to IMesher/Meshmerizer which enables/disables mesh caching. Since BulletSim caches and tracks the unmanaged memory version of meshes, the Meshmerizer itself does not need to cache built meshes once BulletSim has made the physical proxy mesh. 2012-11-29 09:24:53 -08:00
Melanie 3b2caa63b0 Rename BulletSim's PhysicsShapeType to BSPhysicsShapeType because it
conflicts with PhysicsShape type defined in later libOMV

Robert Adams cbc7e7bf85 BulletSim: Make avatar capsule so it is not circular.
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.
2012-11-21 16:43:53 -08:00
Robert Adams 8dd5813889 BulletSim: rename SHAPE_AVATAR to SHAPE_CAPSULE with the eye to eventually having mesh avatars. 2012-11-21 16:43:06 -08:00
Robert Adams 65e55ada87 BulletSim: uplevel FixedShapeKey out of ShapeData structure (since it is getting simplified out of existance someday) and update all the references to same. 2012-11-21 16:42:58 -08:00
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 4d29488216 BulletSim: change PositionSanityCheck to apply a force to correct position corrections (below ground and floating). 2012-11-21 16:42:42 -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 f53b4e7a21 BulletSim: Add RawPosition and RawOrientation to BSPhysObject and rename MassRaw to RawMass. Fix BSShapeCollection to use Raw* for creating the body to eliminate exception from referencing the physical body before it has been created. 2012-11-03 21:15:22 -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
Robert Adams 52be581f71 BulletSim: remove center-of-mass setting for linksets because it causes the constraint calculation to pull the objects together. 2012-11-03 21:14:49 -07:00
Robert Adams 804b332d45 BulletSim: Add banking and other new code to vechile dynamics. Add third party license and contributor in for for Aurora-Sim project for physics code. 2012-11-03 21:12:46 -07:00

2012-10-19 15:43:31 -07:00
Robert Adams f422b9b388 BulletSim: reorder avatar collision checking to eliminate double collision_end.
Various tweekings to avatar shape/mass/inertia/etc.
