f1be4ab221 only update aabb of active objects, thanks Peter Tchernev for reporting (http://bulletphysics.com/Bullet/phpBB3/viewtopic.php?f=9&t=1764 ) 
move debug aabb rendering from updateAabb to debugDrawWorld

5f5dfcf6b8 added btGetVersion(), return integer without the fraction: for example 2.64 returns 264. 
moved more demos into AllBulletDemos

87df3d0f32 Based on feedback from another professional game company, there are several improvements, including some API change... 
Some dynamic memory allocations have been replace by pool allocation or stack allocations.
quantized aabb versus quantized aabb overlap check is made branch-free (helps a lot on consoles PS3/XBox 360)
Collision algorithms are now created through a new btDefaultCollisionConfiguration, to decouple dependency (this is the API change):
Example:
	btDefaultCollisionConfiguration* collisionConfiguration = new btDefaultCollisionConfiguration();
	m_dispatcher = new	btCollisionDispatcher(collisionConfiguration);

1f7646f72a Refactoring to enable multi SAP broadphase. 
This was already planned, and Pierre Terdiman recent thread motivated me to decouple the paircache from the sweep and prune.

5f8873c339 support diamondsubdivision (thanks Jay for contribution) 
support user-defined broadphase collision filtering (thanks Marten)
make sure btSimpeDynamicsWorld doesn't use cache friendly optimization in the solver (added an assert, and updated BasicDemo)

cad28a8b35 allow for float data, and prepare for 'quad edge flip', either re-use the first triangle vertex, or second (re-use index 00 or 01) 2007-06-27 19:56:18 +00:00

9099d6bed5 updated vehicle demo to load heightfield data from file 2007-06-27 19:12:09 +00:00
ejcoumans
59cb275c9c basic support for height fields. They are producing temporary triangles, similar to the plane shape. 
VehicleDemo demonstrates heightfield support.

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)

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.

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

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

6738ed329d ASSERT -> btAssert 
Added btStackAlloc to Bullet (right now only used by btGjkEpa)

56e135874b added angular limits to the Generic D6 constraint. Works for small angles. Will add a check for different combinations, and use different extraction of ordering of rotation from the diff quaternion. 
Improved vehicle interpolation of wheels, and added Z-up axis option for the Demo
made 'getWorldTransform' const method in btMotionState
added future 'deactivationCallback'(not used yet)

c3ed55057c - added linear limits to btGeneric6DofConstraint and made sure the linear axis are in local space of objectA 
- use microseconds instead of milliseconds for deltatime

eb23bb5c0c merged most of the changes from the branch into trunk, except for COLLADA, libxml and glut glitches. 
Still need to verify to make sure no unwanted renaming is introduced.
