c1a54d9edc Attempts to improve performance. Not much gain yet, but good to experiment what has effect and what hasn't. 
Added 'DO_BENCHMARK_PYRAMID' to CcdPhysicsDemo.

02e5f2dd8e void btDiscreteDynamicsWorld::solveConstraints(btContactSolverInfo& solverInfo) 
sortedConstraints.heapSort(btAlignedObjectArray<btTypedConstraint*>::less());

should be

sortedConstraints.heapSort(btSortConstraintOnIslandPredicate);
Thanks  	Clemens Unterkofler for pointing this out!

3c1ba0023b NULL is not yet defined because this header is sometimes included before stdio.h or stddef.h - rather than change a bazillion places where the header is included, I'll just use 0 instead. 2007-03-06 18:14:37 +00:00

a4a3474fb5 The macro 'btFullAssert' is used like this: 
btFullAssert ( yadda_yadda ) ;

...in the btScalar.h header, it's defined as:

    #define btFullAssert

...which means that the statement above becomes:

    ( yadda_yadda ) ;

...which means that code may actually be compiled and executed (unnecessarily) - and even when the code is something simple like:

    ( i > 0 && i < 3 ) ;

...the GCC tosses out a 'statement with no effect' warning - before
it optimises away the code.

The fix is:

   #define btFullAssert(x)

...so that the macro still takes a parameter which is now removed
from the sources so you get:

    ;

...which is guaranteed not to generate code.

054d672592 - removed STL from the Bullet library: replace std::vector by btAlignedObjectArray. Also removed the std::set for overlapping pair set, and turned it into an overlapping pair array. The SAP only adds objects, never removed. Removal is postponed for during traversal of overlapping pairs (duplicates and non-overlapping pairs are removed during that traversal). 
- added heap sort and binary search/linear search to btAlignedObjectArray
- fixed wrong cast, thanks Hamstray, http://www.continuousphysics.com/Bullet/phpBB2/viewtopic.php?t=1015

b73900bc60 Improved performance of convex collision shapes, cache local AABB instead of recomputation. This fixes issue with very slow performance in larger .bsp levels. 
Moved some asserts into 'btFullAssert', which is disabled by default (see btScalar.h to enable them). This is to speed-up debugging.

e610598d33 - Added compressed/quantized AABB tree, 16 bytes per node, while supporting 32-bit (triangle) indices. Should be faster and smaller then original version (quantized aabb check is done in integer space) 
Original aabb nodes are 44 bytes (with full floating point precision and additional part index)
- added meter-unit scaling support in ColladaConverter.cpp

581468ceec Added btCapsuleShape. This could already be simulated by simply adding 2 spheres to the btMultiSphereShape, but this was bad documented/unknown. 
For tapered capsules, you can still use btMultiSphereShape, just pass 2 spheres with different radius.
