ced94d63bf Thanks to Mårten Svanfeldt for the contribution: 
- optionally disable collisions between bodies that are linked with constraints
- improved debug rendering with support for compounds, spheres, capsules

a0c5401033 bugfix, wrongly assigned value to a local variable (copy/paste bug).

cad28a8b35 allow for float data, and prepare for 'quad edge flip', either re-use the first triangle vertex, or second (re-use index 00 or 01) 2007-06-27 19:56:18 +00:00

769809e3a7 disabled memcpy by default, it seems to be opening a can of worms, some platforms/compilers have it defined in <memory.h>, others in <string.h> etc 
also for placement new, include <new> rather then <memory.h>
Thanks Marten Svanfeldt for the help

272a7dfac4 More work on multi-threaded version, fixed alignment issues in DMA. 
BulletMultiThreaded shared implementation works now on both Win32 Threads and PS3 Cell SPU.

65d10d7b12 Fixes in aligned object array, to call copy constructor, and not the assignment operator, operator= 
Also allows to use the array for classes with virtual methods.

c1250cd26a Planar triangle meshes with zero extends (in any direction) could cause quantization failures (division by zero). 
Added a positive value to quantization AABB (doesn't affect performance).

cf2337ed7b - Fixed a bug in btAxisSweep3 (sweep and prune) related to object removal. Only showed up when at least one btStaticPlaneShape was inserted. 
Thanks tbp for more details on reproducing case.
- Fixed issue with full 32bit integers in btAxisSweep3 (define BP_USE_FIXEDPOINT_INT_32), it used only 65536 for quantization, it should use full integer space (0xffffffff)
- Added 'getForwardVector' and getCurrentSpeedKmHour utility functions to btRaycastVehicle
- Fixed local scaling issues (btConvexTriangleMeshShape, btBvhTriangleMeshShape, removed scaling from btMatrix3x3). Thanks Volker for reporting!
- Added second filename search, so that starting BspDemo and ConvexDecompositionDemo from within Visual Studio (without setting the starting path) still works

3ad4316622 the relative path #include gives troubles in some cases. 
I need to revert all those back (after Steve Bakers changes a while back).
All includes should really be relative to the 'src' folder, or wherever the developer copies all the headerfiles.

82c8687881 - initialize m_unusedW to avoid some warnings. 
- added angularFactor to 'cachefriendly' constraint solver

2db8bfa3d6 Fix (needs more testing) in btRigidBody::setCenterOfMassTransform, assign m_interpolationWorldTransform = xform; instead of m_worldTransform; 
Thanks Jay for reporting
Added braking capability to btRaycastVehicle, see Bullet/Demos/VehicleDemo/VehicleDemo.cpp
Added glutKeyboardUpFunc, for vehicle demo (keep accelerating/breaking, until key released/UP). Hope this is compatible with most GLUT implementations.

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

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.

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),

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.
