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

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

6d6ef5d3dc fixed many memory leaks 
added working shadows, using basic shadow mapping

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

531af1b394 add ray-convex CPU implementation, make CPU raytest default for now 
tweak/increase the b3Config values again, so it works better on the Macbook Retina GPU.

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.

9a92eecf10 allow larger amount of rigid bodies, dynamically increase b3Config limits 
avoid crashes in instancing renderer if instance maximum is exceeded.

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)

1185de51d5 experiment with first-level batching using object index instead of spatial hash in uniform grid (to avoid tuning average object size for uniform grid) 2013-05-03 01:14:34 -07:00

e999903c15 resolve some naming conflicts between Bullet 3.x and Bullet 2.x 
add BasicGpuDemo that bridges Bullet 2.x and Bullet 3.x (still preliminary/crashing/instable)
