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.

b14ccdaa57 rename treshold into thresold (spelling mistake) 
added cr/linefeed at end of btDefaultMotionState.h

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)

d878885db4 updated quickstep solver (for comparison), enabled GPU physics again (but WIN32 doesn't have the VertexTextureSupport enabled) 2006-10-13 23:58:52 +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'

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.

84afe40064 changed version number, moved SphereSphere algorithm and decreased default number of rigidbodies from 3250 back to 250. 2006-09-19 04:58:11 +00:00

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 :)
