erwin coumans 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.

Erwin Coumans 7d79555f50 only disable fastscan in radix sort for __APPLE__, this should improve Linux performance (previously it went through the slower path under Linux) 2013-06-19 23:18:17 -07:00
Erwin Coumans fa4394c378 remove bullet2.patch, the file is not necessary anymore. 
You can use Bullet 3.x standalone, or you can use Bullet3+Bullet2 by checking out the source code of both repositories at the same location,
and then use premake --bullet2gpu gmake (or vs2010, xcode4) to generate the combined project, with App_BasicGpuDemo_* test app.

erwin coumans aa1c2db35a Add support for b3Generic6DofConstraint in Bullet, CPU only for now. Also the b3GpuDynamicsWorld supports conversion of this constraint. 
This means, picking works both with and without holding SHIFT (rayTest is only implemented for spheres)
 2013-06-19 12:28:51 -07:00
erwin coumans f10eb86f55 enable the GPU ray test in BasicGpuDemo, only for spheres at the moment 2013-06-19 00:12:06 -07:00
erwin coumans 481d54967f Fixes in raycast (against sphere), point 2 point constraint 
Picking test works, holding shift in App_BasicGpuDemo_*
 2013-06-18 19:33:45 -07:00
erwincoumans 9a92eecf10 allow larger amount of rigid bodies, dynamically increase b3Config limits 
avoid crashes in instancing renderer if instance maximum is exceeded.
 2013-06-17 17:05:01 -07:00
erwincoumans 561a44e5d8 Try to avoid crashes if memory allocations fail 
Deal with cases exceeding allocations of bodies/shapes above the limits set in b3Config
(work-in-progress )

 2013-06-14 12:10:16 -07:00
erwincoumans 02a858e7c1 pass in b3Config 2013-06-08 11:32:29 -07:00
erwin coumans 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)
 2013-06-08 11:08:44 -07:00
erwin coumans 3f10082aa3 add missing rayCast kernel 2013-06-07 20:47:47 -07:00
erwincoumans 9fe48d887d b3GpuDynamicsWorld improvements: 
apply forces
copy linear/angular velocity every frame at the CPU side, initial velocity works now
hook up setGravity
Note: the 'stepSimulation' for GPU only simulates a single simulation frame.
