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

a5bf6a1254 use solvermode 'randomized' and not warmstarting 2007-02-13 16:47:04 +00:00

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.

df9230327c Contribution to add optional double precision floating point support. Define BT_USE_DOUBLE_PRECISION for all involved libraries/apps. 2006-12-16 05:51:30 +00:00

b6d1b4c94e Added btNearCallback. This is similar to Open Dynamics Engine (ODE) dNearCallback, but important differences: 
- contact points are persistent (lifetime more then one frame, for warmstarting/incremental contact point management)
- continuous collision detection, time of impact
Added btRigidBody::isInWorld(), returns true if btRigidBody is inside a btCollisionWorld/btDynamicsWorld derived class
Added angularFactor to btRigidbody, this helps some character control (no angular impulse applied)

8cbd721a1f added some brute-force way to shrink convex polyhedra (to compensate collision margin) 
made Extra/EPA compile again, updated Pierre's testbed to compile out-of-the-box

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

23c64fb0db more solver experiments, randomize the order of contact points, not just manifolds 
use #defines for constants, rather then const btScalar

07873854a4 more small refactoring: some methods were still upper-case. 2006-11-03 04:32:48 +00:00

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.

3fe3b11924 use Dispatcher in ConcaveConvexCollisionAlgorithm (so it uses the registered collision algorithm, not hardcoded convexconcave) 
improved performance of constraint solver by precalculating the cross product/impulse arm
added collision comparison code: ODE box-box, also sphere-triangle
added safety check into GJK, and an assert for AABB's that are very large
write partid/triangle index outside of GJK

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)

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'

2b1657b1dd Refactoring: another huge number of changes, renamed methods to start with lower-case. 2006-09-28 01:11:16 +00:00

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 :)
