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 e1ac683154 BulletSim: fix crash when deleting llVolumeDetect enabled objects. Bullet's check for an object being linked into the world does not work for Bullet's ghost objects so BulletSim was deleting the object while it was still linked into the physical world structures. 2013-04-22 16:50:06 -07:00

a little clearer.
2013-04-01 18:03:09 -07:00
Robert Adams 84eb25da23 BulletSim: stop an avatar from moving if standing on a stationary

or objects while still allowing an avatar to be moved if standing
on a moving object.
2013-03-31 22:19:44 -07:00
Robert Adams 933ac60746 BulletSim: not quite functional axis lock code. 2013-03-31 22:19:43 -07:00

2013-03-31 22:19:41 -07:00
Robert Adams 6a9630d2bd BulletSim: fix race condition when creating very large mega-regions.
The symptom was exceptions while creating physical terrain.
Reduce default terrain mesh magnification to 2 from 3 because the
higher resolution uses a lot of memory and doesn't solve the terrain
smoothness for vehicles.
Added comments here and there and improved some debugging log messages.
2013-03-28 10:59:18 -07:00
Robert Adams 3f9b274180 BulletSim: tweaks to terrain boundry computation. No functional changes. 2013-03-28 10:59:16 -07:00
Robert Adams abde0d4efb BulletSim: prevent asset fetching loop when the fetched asset fails to mesh.
Check for the case where the fetched mesh asset fails meshing (degenerate
triangles or no physical mesh). In this case, the asset is marked 'failed'
and BulletSim doesn't keep trying to fetch over-and-over trying to get a
good asset.
2013-03-26 15:02:10 -07:00
Robert Adams 285dc554ec BulletSim: new algorithm for vertical attraction which uses quaternion

Robert Adams f783b9169f BulletSim: parameterize C# HACD hull creation. Add feature of reducing max hull count for simple (non-cut prims) meshes. 2013-03-25 15:40:41 -07:00
Robert Adams 90b9121e66 BulletSim: change 'degenerate mesh' message from Error to Debug because there
seem to be lots of sculpties with this problem while the condition really doesn't
change region operation.
2013-03-19 17:15:24 -07:00
Robert Adams 8360223fed BulletSim: code to generate a higher resolution terrain mesh. Parameter
TerrainMeshMagnification controls number of vertices generated per

Robert Adams 0baa2590be BulletSim: check for completely degenerate meshes (ones with all

throwing and exception.

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

   to see the arch problem.

Justin Clark-Casey (justincc) 1f1da23097 Bump version and assembly version numbers from 0.7.5 to 0.7.6
This is mostly Bluewall's work but I am also bumping the general version number
OpenSimulator 0.7.5 remains in the release candidate stage.
I'm doing this because master is significantly adding things that will not be in 0.7.5
This update should not cause issues with existing external binary DLLs because our DLLs do not have strong names
and so the exact version match requirement is not in force.
2013-02-05 00:23:17 +00:00

teravus ba9d6b7337 * Repairs the Object updates, Collision updates, and Child Prim methods making the bulletXNA engine work again.
* The only thing that had an issue was when creating a new RigidBody, BulletXNA didn't know the type SimMotionState and the upcast type is unknown in the constructor.   Therefore, I had to update the IMotionState with a new method 'SetBody'.    All of the duplicated type information has been removed and BulletXNA is not relying on any non-standard types external to the library.
