4c00b674b3 Optimize Dbvt trees in place 
Instead of allocating new vectors for each partition, simply partion the
nodes in place and pass the corresponding ranges to the next phase.

dcd02a1e15 add option to terminate PGS constraint solvers based on a least square residual threshold 
(for example solverInfo().m_leastSquaresResidualThreshold = 1e-7 and use large m_numSolverIterations
disable sphere-sphere contact cache, it is buggy (some contact point stay in the cache, when sphere penetrates more than total margins)
tweak some gpu demo settings

ef943bdcf0 Add "missing" virtual dtor 
Make the dtor of b3DynamicBvhBroadphase virtual, to match that the type
has other virtual methods. This silences a -Wvirtual-dtor warning.

6c9ce344ea fix shadowmap crash on some Intel GPUs, see https://github.com/bulletphysics/bullet3/issues/4 
remove targetdir from all libraries in premake, so it is much easier to create a separate folder for all binary+lib
transmit the serialized btMultiBody data back from server to client, after the server loads a URDF file. This includes base+link+joint names
tweak the serialization routines, so it is easier to skip pointers and to serialize directly to a shared memory buffer
also tweak the serialization code to allow to process data without 'DNA' schema data (assuming file-DNA = memory DNA)

2e55d03fd9 more fixes towards working convex-convex, in case of (too) many edge-edge cases: 
1) sample directions over a unit sphere and
2) add a contact, using mpr

271f458837 Ported Minkowski Portal Refinement mpr.c from libccd to OpenCL, for bettwe edge-edge performance (and additional contact point for degenerate/high detailed convex shapes) 
Removed b3RigidBodyCL, replace by b3RigidBodyData and b3RigidBodyData_t shared between C++ host and OpenCL,
Same for b3InertiaCL -> b3InertiaData

3fe969c4ee b3Solver -> pass pointer to source instead of 0 (was left over from a debugging session), thanks to David for the report 
Break up clipHullHullConcaveConvexKernel into multiple stages, so it might 'fit' in Apple's OpenCL implementation
Implemented bvhTraversalKernel and findConcaveSeparatingAxis on CPU (debugging, possible future CPU version)

677722bba3 support compound versus compound collision shape acceleration on GPU, using aabb tree versus aabb tree. 
Remove constructor from b3Vector3,  to make it a POD type, so it can go into a union (and more compatible with OpenCL float4)
Use b3MakeVector3 instead of constructor
Share some code between C++ and GPU in a shared file: see b3TransformAabb2 in src/Bullet3Collision/BroadPhaseCollision/shared/b3Aabb.h
Improve PairBench a bit, show timings and #overlapping pairs.
Increase shadowmap default size to 8192x8192 (hope the GPU supports it)

ac23dbc4be contact normal should point from B to A (to be consistent with Bullet 2.x)

3bf003ace1 change lcpp Lua preprocessor, to keep #defines and comments, remove empty lines 
remove duplicate data in b3Contact4 (now in btContact4Data shared between CPU/C++ and OpenCL)
OpenCL kernels use #include "Bullet3Collision/NarrowPhaseCollision/shared/b3Contact4Data.h"
Increase number of batches back to 250 (from 50), need to fix this hard coded number (see https://github.com/erwincoumans/bullet3/issues/12)

733f9027fb Deterministic simulation for concave and compound collision shapes: added childShapeA/B to b3Contact4 + sort on them 
Use tetrahedra instead of barrel for convex demo (until performance for edge-edge is improved)
Increased #overlapping pair capacity from 12 to 16 / objec

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.
