28f6e0fbd3 towards GPU joint (non-contact) constraint solving. The ConstraintDemo shows that CPU performance is very good, so not much performance win is to be expected. 2013-07-02 21:13:42 -07:00

a69ba48de4 Move b3Quickprof.* from Bullet 3.x src folder to btgui/Timing 
The Bullet 3.x B3_PROFILE can be customized using b3SetCustomEnterProfileZoneFunc/b3SetCustomLeaveProfileZoneFunc defined in Bullet3Common/b3Logging,
so you can hook Bullet 3.x up to your profiler of choice.
The Demos3/BasicGpuDemo will show the Bullet 3.x timings inside the Bullet 2.x btQuickprof profiler.

100449d76f faster scene construction when not using instancing (avoid copy individual vertices/shapes to GPU, but do it afterwards in a batch), copy GPU data in 'writeAllBodiesToGpu' method 
add option --no_instanced_collision_shapes, this only applies to the 2 benchmark screnes at the moment
always use the user specified b3Config file, so the settings can be set at runtime, not just at compile time
adjust default constants in b3Config (needs more tweaking, ideally at run-time)

9fe48d887d b3GpuDynamicsWorld improvements: 
apply forces
copy linear/angular velocity every frame at the CPU side, initial velocity works now
hook up setGravity
