8ad6d7f401 more Bullet 2.x upgrading. fair amount of functionality is now restored, not all yet. 2006-11-21 12:26:05 +00:00

46234f90ce Removed old Blender/extern/bullet, and upgraded game engine to use Bullet 2.x 
All platforms/build systems: either upgrade to use extern/bullet2, or disable the game engine until the build is fixed.

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)

4a5826fa83 Patch from Charlie: 
Cleared the python dictionary at the end of the game engine, should fix some issues,
also reverted the python controller changes, related to this

This should fix the following bugs:
[ #3789 ]
[ #3815 ]

possiblyy fixes:
[ #3834 ]

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.

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)

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.

97a4e4f88d a bunch of small warnings fixes: 
newline missing at end of file fixes:
TypedConstraint.h WheelInfo.h RaycastVehicle.h VehicleRaycaster.h
CcdPhysicsEnvironment.cpp

radiance_hdr.c fixed the following warning by changing type of local variable:
radiance_hdr.c:357: warning: pointer targets in passing argument 3 of
‘fwritecol rs’ differ in signedness

edgeRender.c,edgeRender.h same thing changed type of local vars to get rid
of warnings about signedness

RAS_OpenGLRasterizer.cpp removed unused variable unit line 1295

90e5a9aa14 Reorganized Bullet physics files, added preliminary vehicle simulation files (disabled). 
Requires some changes to projectfiles/makefiles/scons, for the added and removed files!

6f3e593105 more graphics patches from Snailrose, 
remove constraint fixed,
Bullet timestep now subdivides Blender game engine timestep, so it runs 60 hertz,
SphereShape reverted to old style, so no support for non-uniform scaled spheres for now,

71991cf41e Some rigidbody dynamics fixes (scaling again) to make Happy 2006 domino simulation to work. 
See http://www.continuousphysics.com/ftp/pub/test/index.php?dir=blender/&file=happy_2006_blend.zip
For the baked dominos. Thanks to Tom M (LetterRip) for the blend.

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.

b6d9fbf0db fixed the mouse-over sensor, 
added raycast support for bullet (no triangle-mesh support, soon)
added python methods for 'getHitObject', getRayDirection, getHitPosition and getHitNormal for mouse over sensor,
which makes it easy for a shootout.blend demo :)

671235b69b Finalised support for compiling BULLET on linux. 
Bullet is now off by default on all platforms until we get an OK
from Erwin. To enable it, change USE_PHYSICS to 'bullet' in your
config.opts.
