472614772f expose some more settings as command-line parameters: 
[--disable_shadowmap] [--shadowmap_size=int] [--shadowmap_resolution=<int>] [--use_jacobi] [--use_uniform_grid]

5ce0b3938f Re-introduce GPU parallel Jacobi solver, called btGpuJacobiContactSolver. There are still some issues, but for basic scene's it works. 
To avoid confusion, rename GPU contact solver to btGpuContactSolver, and constraint (non-contact) solver to btPgsConstraintSolver.

8f3051fdf1 add ImplicitCloth demo, by Stan Melax 
add SimpleOpenGL3App, used in ImplicitCloth demo. The Bullet 3.x demos should use this as a template, it will clean up some of the mess.

8faac34801 move ExplititEuler cloth solver to its own file, so it can be replaced by PDB, implicit euler etc 
add wireframe toggle ('w' key)
add --paused command-line option to start simulation in paused mode
render cloth using drawPoints method

ad8d0e32f4 expose 2 new command-line options [--disable_cached_cl_kernels] [--load_cl_kernels_from_disk] 
on Windows (_WIN32) debug output goes to BOTH console and Visual Studio output log window.

d32629dbe2 add the option to load a set of AABB's from a file, see PairBench 
You can use the following command-line arguments:
App_Bullet*.exe --selected_demo=10 --cl_platform=1 --pair_benchmark_file=64006GPUAABBs.txt --benchmark

2c019d579f reduce memory allocation, lack of GPU memory totally destroys performance on my GTX 650M on the Macbook retina 
add some keys to toggle gui drawing and shadows

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)

338118b3c6 expose the number of frame that the benchmark mode runs as commandline parameter:

2793a174c6 added fracture scene .bullet file (doesn't work well yet) 
added tetrahedral mesh test scene
expose b3Config as member variable for demos.
move a 'glFlush' out of the innerloop (render performance)
SSE -> SSE2 in premake
fix crash in broadphase (when no aabb's exist)

a5b73e7c76 use Syoyo Fujita's Wavefront obj loader. made some performance improvements in debug mode for Visual Studio 
use Maya style controls under Windows (need to fix Linux/OSX) use ALT+mouse to rotate, and mouse pick to pick objects

ab125fbb6d implement GPU breakable constraints 
add GPU fixed constraint
fix performance issue with concave meshes (didn't clear the number of concave-convex pairs, so it increased every frame)

2aad8419b7 add support for picking, using point 2 point constraint 
allow to remove constraints by unique id
added tiny wavefront loader, plan to use this instead of existing slow wavefront loader

c4375a09e4 added GPU joint solver for non-contact constraints. Only point 2 point version for now, will add some other constraints soon (changes are very local) 2013-07-09 10:46:47 -07:00

f2cc840c31 move shaders to .glsl files and stringify to .h file.

start with shadows using shadowmap, not working yet
add experimental 'ignore' body index in raycast, using b3HitInfo.m_m_hitResult2

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)
