ejcoumans 9531ec4b30 most basic rigid body simulation 
lacks object deactivation and constraints, vehicles etc.
 2006-09-26 21:31:44 +00:00
ejcoumans 37a53ee7d9 small cleanup in the DemoApplication, removed references to obsolete PHY_ShapeProps/PHY_MaterialProps 
removed deletion of motionstate in CcdPhysics/CcdPhysicsController destructor
disabled m_type optimization in SimdTransform (making the memory size 64 byte, potentially more cache friendly)
fixed a bug in island generation, causing the activation not propagating in one frame, but one 'layer' of rigidbodies at a time
 2006-09-26 18:59:29 +00:00
ejcoumans 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.

ejcoumans 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 :)
