ed064df60b fixed bug in contact manifold generation, concave and compound objects require point with deepest penetration. 2006-09-05 04:16:35 +00:00

7970da34ed 'Better' cleaning for bullet (trickier to clean than most, since it is two 
libraries split among many subdirectories).

bf49ff5050 Got a license from Intel for VTune, thanks! First performance analysis showed unexpected slowdown due to island management. Added path-compression to UnionFind, and iterate just over island-id's, rather then all objects, when filling islands. 2006-08-29 23:27:27 +00:00

cd5a7fbe84 workaround for a irregularity/bug in physics system (happens very seldom, just 1 report so far, linear velocity/AABB becomes NaN) 2006-06-22 01:10:50 +00:00

2c9214bcc9 improved GJK accuracy for large objects 2006-05-23 22:35:31 +00:00

ab71e2a9b5 -added basic support for GameActuator 'load game', relative paths were broken, just load file into memory and load blend from memory. 
-near sensor support
- python binding for PhysicsConstraints.setNumTimeSubSteps (dividing the physics timestep to tradeoff quality for performance)

bf38cf6f80 Bullet: added per-contact point user-cache, + callback. This allows Collision Detection to be used more generically, and still have persistent info stored, like contact constraints. 
Bullet: added support for restitution

ede20c166a - Charlie provided a work-around for some armature related crashes 
- fixed some Bullet raycasting (hitfraction was not properly updated for static meshes)
- removed some cvs tags in Bullet's BMF _Font files (they keep on conflicting when duplicated in different repositories)
- set default linearsleepingtreshold explicitly

93c47e1071 - Added support for kinematic objects (interaction between rigidbodies), deriving linear/angular velocity from previous transform/current transform and deltatime. 
- Made another attempt to migrate from Sumo to Bullet: import of older files automatically switch to Bullet, but you can override it, and save the file in 2.42 version. then it stays Sumo physics.

f51d1ef7d6 - fixed Bullet noResponse/ghost mode 
- added ccd option (future use, very basic and inefficient)
- some internal Bullet refactoring/improvements

45d0123a59 fixed several internal Bullet rigidbody dynamics bugs:

- persistent manifold renamed value,
- cylinder penetration depth fixed,
- memory leak for persistent manifold

904a0792f7 Bullet physics: fixed some accuracy problem (square length should be compared to square epsilons), and more collision sensor work + deactivation issues 2006-04-17 06:27:57 +00:00

176641b273 ==Something very minor== 
To get blender to build I needed to comment out:

#include "NarrowPhaseCollision/EpaPenetrationDepthSolver.h"

Erwin, please check.

36fd42ac85 more Bullet physics improvements, mainly stability and performance related. 
AddObjectActuator has new python method to immediately create objects (this allows to create multiple objects in 1 frame in different positions)

e8ce63fcf9 more physics work: fixed some deactivation bug, improved contact constraint stability and friction (lower the number of iterations). 2006-03-29 03:11:30 +00:00

af9573e9ea Synchronized Bullet physics to latest version. 
- Changed license from MIT to ZLib.
- Added 3D Sweep and Prune contribution
- More stable native constraint solver

Sorry for any inconvenience caused by this checkin.
All Blender buildsystems require update: added files and moved files.

ca6aca0c07 restoring minimum debug build on msvc6 projects 
-no GE
-no OpenExr / hum.. may be that's why storing a PNG does not crash

39fcd3586f Lots of stupid warning fixes: 
Added newlines at end of a bunch of files that didn't have them.
removed a couple of unused variables and an extra ';'
(Also removed config.h crap from these files)

9119b6e8a5 Fixed several bugs: python refcounting related and Bullet related (basic add/remove object support, bounding volume hierarchy). Added a few files, updated the Bullet scons. Vc6/7 Bullet projectfiles need to add a couple of files: 'Bullet/CollisionShapes/BvhTriangleMeshShape.cpp', 
'Bullet/CollisionShapes/ConvexTriangleCallback.cpp',
'Bullet/CollisionShapes/EmptyShape.cpp',
'Bullet/CollisionShapes/OptimizedBvh.cpp',
'Bullet/CollisionShapes/TriangleCallback.cpp',
'Bullet/CollisionShapes/TriangleIndexVertexArray.cpp',
'Bullet/NarrowPhaseCollision/ManifoldContactAddResult.cpp'.
Sorry, no armatures fix yet.
