ejcoumans bc3f9535ad cleaned up, removed warning under MSVC2005 (Level 4) 
Mostly related to alignment and unused variables

ejcoumans 2cf026aae3 allow incremental refitting of the quantized aabb tree 2007-04-10 21:40:43 +00:00
ejcoumans 853bafb7ae Get the open source Bullet library more in sync with Playstation SPU version 2007-04-10 01:02:58 +00:00
ejcoumans 9546633ade Added 'cache friendly' tree traversal format, and traversal. Array of subtrees with specified maximum size. This is useful to fit tree traversals on SPU. 2007-03-27 21:02:45 +00:00
ejcoumans 7adc0742e3 Added demo code that show recursive traversal on tree data that doesn't have explicit left/right child pointers. 
Can also be used as starting point for tree versus tree.

ejcoumans 22fa7abe39 updated version to 2.49, updated ChangeLog.txt 2007-03-21 19:23:08 +00:00
ejcoumans c791a3192c In the copy constructor initializer list of LocalRayResult in 
btCollisionWorld.h  line 139 (version 2.48) it reads:
m_localShapeInfo(m_localShapeInfo),
which should be:
m_localShapeInfo(localShapeInfo),

ejcoumans 1655fbc2c0 fixed some windows related defines, and made btClock optional (behind #define) 2007-03-07 00:33:11 +00:00
ejcoumans 57883344df removed testing assert(0) 2007-03-07 00:22:40 +00:00
ejcoumans adfdea5ca6 replaced #include "new.h" to #include <new> 2007-03-06 23:40:06 +00:00
sjbaker 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
sjbaker 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.

ejcoumans 79d53cd346 updated version 2007-03-06 10:26:11 +00:00
ejcoumans d70e60cc9a updated changelog 2007-03-06 10:23:44 +00:00
ejcoumans 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

ejcoumans f8b714cd42 disable scaling in collada converter, it doesn't give good results in most files. 2007-02-28 00:48:10 +00:00
ejcoumans 1db0721318 removed unit meter in jenga.dae 2007-02-26 05:18:52 +00:00
ejcoumans 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.

ejcoumans 559c4e85d8 updated ChangeLog.txt 2007-02-25 06:14:28 +00:00
ejcoumans 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
