 2007-06-13 01:04:43 +00:00

 2007-06-01 01:24:47 +00:00

ejcoumans 8b453dfd9c Added fix to changelog, with credits to Phil Knight for reporting and help to fix it. 2007-05-23 20:29:04 +00:00
ejcoumans c1250cd26a Planar triangle meshes with zero extends (in any direction) could cause quantization failures (division by zero). 
Added a positive value to quantization AABB (doesn't affect performance).
 2007-05-23 20:09:46 +00:00
ejcoumans cf2337ed7b - Fixed a bug in btAxisSweep3 (sweep and prune) related to object removal. Only showed up when at least one btStaticPlaneShape was inserted. 
Thanks tbp for more details on reproducing case.
- Fixed issue with full 32bit integers in btAxisSweep3 (define BP_USE_FIXEDPOINT_INT_32), it used only 65536 for quantization, it should use full integer space (0xffffffff)
- Added 'getForwardVector' and getCurrentSpeedKmHour utility functions to btRaycastVehicle
- Fixed local scaling issues (btConvexTriangleMeshShape, btBvhTriangleMeshShape, removed scaling from btMatrix3x3). Thanks Volker for reporting!
- Added second filename search, so that starting BspDemo and ConvexDecompositionDemo from within Visual Studio (without setting the starting path) still works
 2007-05-20 16:21:14 +00:00
ejcoumans 3ad4316622 the relative path #include gives troubles in some cases. 
I need to revert all those back (after Steve Bakers changes a while back).
All includes should really be relative to the 'src' folder, or wherever the developer copies all the headerfiles.
 2007-05-09 19:26:31 +00:00
ejcoumans ceee6d7e14 renamed ${OPENGL_glU_LIBRARY} into ${OPENGL_glu_LIBRARY} 
This allows MinGW32/MSYS makefiles (using cmake -G "MINGW Makefiles") to build (used to have a link error against gluLookAt etc)
 2007-04-29 18:26:32 +00:00

ejcoumans 2db8bfa3d6 Fix (needs more testing) in btRigidBody::setCenterOfMassTransform, assign m_interpolationWorldTransform = xform; instead of m_worldTransform; 
Thanks Jay for reporting
Added braking capability to btRaycastVehicle, see Bullet/Demos/VehicleDemo/VehicleDemo.cpp
Added glutKeyboardUpFunc, for vehicle demo (keep accelerating/breaking, until key released/UP). Hope this is compatible with most GLUT implementations.
 2007-04-22 15:23:20 +00:00
ejcoumans bc3f9535ad cleaned up, removed warning under MSVC2005 (Level 4)

ejcoumans 853bafb7ae Get the open source Bullet library more in sync with Playstation SPU version 2007-04-10 01:02:58 +00:00
ejcoumans 9546633ade Added 'cache friendly' tree traversal format, and traversal. Array of subtrees with specified maximum size. This is useful to fit tree traversals on SPU. 2007-03-27 21:02:45 +00:00
ejcoumans 7adc0742e3 Added demo code that show recursive traversal on tree data that doesn't have explicit left/right child pointers. 
Can also be used as starting point for tree versus tree.
 2007-03-26 19:19:25 +00:00
ejcoumans 22fa7abe39 updated version to 2.49, updated ChangeLog.txt 2007-03-21 19:23:08 +00:00
ejcoumans c791a3192c In the copy constructor initializer list of LocalRayResult in 
btCollisionWorld.h  line 139 (version 2.48) it reads:
m_localShapeInfo(m_localShapeInfo),
which should be:
m_localShapeInfo(localShapeInfo),

Thanks frinkiac8
 2007-03-21 19:04:44 +00:00

 2007-03-20 20:12:23 +00:00

ejcoumans 79d53cd346 updated version 2007-03-06 10:26:11 +00:00
ejcoumans d70e60cc9a updated changelog 2007-03-06 10:23:44 +00:00
ejcoumans 054d672592 - removed STL from the Bullet library: replace std::vector by btAlignedObjectArray. Also removed the std::set for overlapping pair set, and turned it into an overlapping pair array. The SAP only adds objects, never removed. Removal is postponed for during traversal of overlapping pairs (duplicates and non-overlapping pairs are removed during that traversal). 
- added heap sort and binary search/linear search to btAlignedObjectArray
- fixed wrong cast, thanks Hamstray, http://www.continuousphysics.com/Bullet/phpBB2/viewtopic.php?t=1015
 2007-03-06 09:59:17 +00:00
ejcoumans f8b714cd42 disable scaling in collada converter, it doesn't give good results in most files. 2007-02-28 00:48:10 +00:00
ejcoumans 1db0721318 removed unit meter in jenga.dae 2007-02-26 05:18:52 +00:00
ejcoumans b73900bc60 Improved performance of convex collision shapes, cache local AABB instead of recomputation. This fixes issue with very slow performance in larger .bsp levels. 
Moved some asserts into 'btFullAssert', which is disabled by default (see btScalar.h to enable them). This is to speed-up debugging.
 2007-02-26 04:59:05 +00:00
ejcoumans 559c4e85d8 updated ChangeLog.txt 2007-02-25 06:14:28 +00:00
ejcoumans e610598d33 - Added compressed/quantized AABB tree, 16 bytes per node, while supporting 32-bit (triangle) indices. Should be faster and smaller then original version (quantized aabb check is done in integer space) 
Original aabb nodes are 44 bytes (with full floating point precision and additional part index)
- added meter-unit scaling support in ColladaConverter.cpp
 2007-02-25 06:11:23 +00:00
ejcoumans 7efef8e394 bumped up version, and ChangeLog.txt 2007-02-21 21:24:25 +00:00

ejcoumans 42278e58dd fixes to add improved double-precision for raycasts 2007-02-14 04:10:55 +00:00
ejcoumans 9b94416d61 allow single raycast to be performed on objects 2007-02-14 04:09:17 +00:00
ejcoumans 4d6ec84630 always update position, even for sleeping objects (is workaround, because sleeping objects never get their motionstate update), needs fixing for optimization 2007-02-14 04:02:14 +00:00
ejcoumans a5bf6a1254 use solvermode 'randomized' and not warmstarting 2007-02-13 16:47:04 +00:00
ejcoumans bf68a742cc by default, disable warmstarting, enable random ordering, 
user can override this using solver->setSolverMode(...)
 2007-02-13 16:14:55 +00:00
ejcoumans c4a83539ca terminate the cleaned filename with zero character, thanks to Jay for reporting this fix! 2007-02-13 16:12:20 +00:00

ejcoumans 8a98639d78 fixed a crashing bug (NULL strings) and change the viewing angle of default camera in the demo 2007-01-31 20:57:14 +00:00
ejcoumans e8ca371a71 Workaround for bad PhysX Collada .dae export from Maya: 
It seems whenever the <rigid_body> has <extra> 	<technique profile="PhysX"><kinematic>true</kinematic> this <rigid_body> should have <dynamic> false</dynamic>.
 2007-01-31 03:22:52 +00:00
ejcoumans 581468ceec Added btCapsuleShape. This could already be simulated by simply adding 2 spheres to the btMultiSphereShape, but this was bad documented/unknown. 
For tapered capsules, you can still use btMultiSphereShape, just pass 2 spheres with different radius.
 2007-01-30 00:09:08 +00:00
ejcoumans 7b5301bb43 accept constraint with single rigidbody 2007-01-19 03:48:54 +00:00

ejcoumans ca973e9322 Fixed AABB tree building, which failed for certain large triangle meshes due to stack overflow. 
Now it has a safer check for unbalanced tree, and forces them to be balanced.
 2007-01-04 22:31:31 +00:00
ejcoumans 99337454e3 Added Steve Baker and Jay Lee as contributors. Added double precision to autogenerated msvc projectfiles as build-configuration. 2006-12-27 05:35:20 +00:00
