b8d5cecfe3 joint (non-contact constraint) solver iterations is now working on GPU, but overall slower because of data copy. 
Will move joint setup to GPU, and then some benefit should be visible.
Don't use 64 alignment, it causes data structures size mismatch between cpu and gpu

01e5472f9f add b3FixedConstraint, with less memory footprint than b3Generic6DofConstraint, and easier to port to OpenCL. 
remove the 'obsolete' part of b3Generic6DofConstraint and b3Point2PointConstraint

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.

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

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.

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)

f73d11d896 tweak default values of b3Config.h so some laptop GPUs can run 128k scenes 
return the result of resize

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
Note: the 'stepSimulation' for GPU only simulates a single simulation frame.
