ed73bce9da Move Bullet 2.x demos in a single demo 'AllBullet2Demos', for now only BasicDemo and FeatherstoneDemo is implemented. 2014-01-05 21:58:30 -08:00

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

181a323631 move b3RaycastInfo.h so it can be used without OpenCL dependency

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

d860e7f51a fix Mac OSX build (compound-compound still broken on OSX) 
remove operator= from b3Vector3 to make it POD/Plane Old Data

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)

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
 2013-07-18 15:55:38 -07:00

1e31073f4b made the simulation deterministic 
disable 'simdwidth' optimization for determinism (need to double-check)
made the spatial batching 3D
 2013-07-14 19:16:33 -07:00

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

f2cc840c31 move shaders to .glsl files and stringify to .h file. 
add crude screenshot facility (using F1 key), it can also be used for debugging
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.
