a6d9e977f7 A bit more work on the cmake build system, copy glut32.dll or glut64.dll into binary directory for out-of-source builds. 
Include .rc resource file (to add icon) for WIN32 cmake.

d051e2eacb First commit of 2008, Happy New Year! 
Add option to compile without btClock and without profiling: comment out USE_BT_CLOCK, and #define BT_NO_PROFILE
Fixed typo/case in #include "LinearMath/btQuickProf.h", in SpuParallelSolver.cpp
Removed unnecessary files from libxml CMakeLists.txt

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

e7caaa28d3 re-organized memory (stack and pool) allocators. this lets the user pass in their own memory allocators. 2007-10-20 02:23:39 +00:00

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.

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)

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

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.

6738ed329d ASSERT -> btAssert 
Added btStackAlloc to Bullet (right now only used by btGjkEpa)
removed default constructors of btCollisionWorld/btDiscreteDynamicsWorld, to reduce link-time dependencies

a9172d8684 Added GIMPACT integration for moving concave meshes (interaction with all other Bullet collision shapes) 
Thanks a lot to Francisco León Nájera for the contribution!

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

4050da0e2f One of the last parts of the refactoring (hopefully), made most members of btCollisionObject protected. 
Also did some work on improving the constraint solver.

33b3ec94f1 more fixes, related to introduction of btMotionState, and using realtime timestep 2006-10-18 04:01:07 +00:00
ejcoumans
3a6942fb91 processed a lot of feedback: added 'realtime' simulation with fixed substeps (and clamping maximum number of substeps), this means that when stepSimulation is called with smaller timesteps then 'fixed substep' the motionstate is interpolated. 
renamed m_ccdSweptSphereRadius,
enabled wireframe debugDrawObject (using debugDrawer)

f3b9dcd714 modified triangle mesh generation, to use btTriangleMesh, which is easier to build then the striding index/vertex arrays alternative. 2006-10-11 20:45:11 +00:00

bf847b839a another large series of changes, related to the refactoring. 
CompoundShapes are tricky to manage with respect to persistent contact points and swapped order of btCollisionObjects,
During dispatch, finding an algorith etc. order can be swapped.
fixed several other issues, related to SimpleBroadphase (removing a proxy was not working)

323a1046fd Cleaned up/simplified construction of a btRigidBody 
Fixed memoryleak in btOptimizedBvh (delete []m_contiguousNodes;)
Changed DemoApplication::localCreateRigidBody, so it adds the rigidbody to the btDynamicsWorld.
Added check for duplicate objects in world when adding.
Added assert to prevent setLinearVelocity on static rigidbodies
Added btCollisionFilterGroups to btBroadphaseProxy
removed duplicate 'btBroadphaseProxy*	m_broadphaseProxy;' in btRigidBody

d38549aa54 more refactoring, removed PhysicsInterface, cleaned up demos to make use of btDynamicsWorld derived classes. 
removed two cached optimizations, type in btTransform and cached inverse transform (todo: test performance impact)
committed fixes that make the code adhere to 'who creates it, also destroys it'

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.

0e04cfc806 First stage in refactoring Bullet: moved Bullet Collision and Dynamics and LinearMath into src folder, and all files in Collision Detection and Dynamics have bt prefix. 
Made all buildsystems to work again (jam, msvc, cmake)

f1627677df Fixed over 500 compile warnings. Mostly: 
* Unused variables.
* Missing newlines at ends of #included files.
* signed int loop variables where the termination condition is an unsigned 'get number of' function.
* 'NULL' used inappropriately for an integer or character constant (NULL is a pointer)
* abstract base classes with no virtual destructor.
* Floating point constants used to initialise integer variables.

8c023e764c started working on some serious performance improvements. now the union find is optimized, the broadphase add/remove overlapping pair was too slow. added a stl::set to keep track of overlapping pairs. this speeds up the set find/remove. work in progress.the SimpleBroadphase is broken. will be fixed tomorrow. 
Did some tests with 3000 rigidbodies, works much smoother now :)
