22fb7d5c1e improve rolling friction using anisotropic direction, to avoid resting in an instable position
(for implicit capsule, cylinder and cone shape)
See Bullet/Demos/RollingFrictionDemo for an example

73b217fb07 Apple contribution for OSX SSE and iOS NEON optimizations unit tests, thanks to Jordan Hubbard, Ian Ollmann and Hristo Hristov.
For OSX:
cd build
./premake_osx xcode4
for iOS:
cd build
./ios_build.sh
./ios_run.sh

Also integrated the branches/StackAllocation to make it easier to multi-thread collision detection in the near future. It avoids changing the btCollisionObject while performing collision detection.

As this is a large patch, some stuff might be temporarily broken, I'll keep an eye out on issues.

852fa3ba30 add the BT_ prefix for all #ifdef guards, to avoid conflicts with developers own header defines.
Fixes Issue 497

//license header
#ifndef BT_RIGIDBODY_H
#define BT_RIGIDBODY_H
class btRigidBody
{
};
#endif //BT_RIGIDBODY_H

e269034494 removed obsolete virtual implementation of 'getUpAxis' in btCylinderShapeZ. It has been replaced by the non-virtual implementation in the base class (for Cell SPU)
Thanks to Paul Dubois for the report, see Issue 407

725411a1f3 added a warning to all serialization structures:
///do not change those serialization structures, it requires an updated sBulletDNAstr/sBulletDNAstr64

44565d20f4 added serialization support for btCompoundShape, btCapsuleShapeX/Z, btCylinderShapeX,Z
make some serialization methods const
prepare for constraint serialization

2f1014268b + Internal improvements for collision shapes
1) add AabbCaching versions of btPolyhedralConvexShape and btMultiSphereShape (this speeds up btMultiSphereShape 'getAabb', and reduces size of btBoxShape)
2) btCylinderShape doesn't derive from btBoxShape anymore
+ Minor fixes in drawing for btMultiSphereShape, btBoxShape.
+ Don't re-generate btDebugFont every frame
+ Disabled velocity prediction for btDbvtBroadphase. Previous default can be restored using btDbvtBroadphase->setVelocityPrediction(1./2.);

2b71784c86 Make getShapeType() a non virtual function.
Add localGetSupportVertexNonVirtual, localGetSupportVertexWithoutMarginNonVirtual, getAabbNonVirtual and getMarginNonVirtual methods to convex shape classes

ea3dfb4ca3 made 'calculateLocalInertia' const, thanks to cgripeos, see http://www.bulletphysics.com/Bullet/phpBB3/viewtopic.php?f=9&t=1514
- applied a large patch to remove warnings
Thanks to Enrico, see http://www.bulletphysics.com/Bullet/phpBB3/viewtopic.php?f=9&t=1568
- removed SSE includes, added #incude <string.h> for memset in Extras/quickstep, thanks Eternl Knight
- disabled 16-byte alignement on btQuadWord class, it causes problems under PS3 Linux. Need to check out why.

eff4fe8ec8 more work on hashed pairmanager. growing doesn't work yet, so need to allocate enough room for the overlapping pairs in advance.
boxbox reports contact point in B, rather then average point
box, cylinder use halfextents corrected for scaling and margin. made the margin in this halfextents explicit in the 'getHalfExtentsWithMargin' and 'getHalfExtentsWithoutMargin'
integrated changed for ODE quickstep solver
replaced inline with SIMD_FORCE_INLINE
some minor optimizations in the btSequentialImpulseConstraintSolver

added cone drawing (for X,Y,Z cones)

685138d033 include paths should not be relative starting with "../
It leads to problems with certain compilers, when Bullet/src is located in a long pathname.
Keep include path starting with "LinearMath/, "BulletCollision/, or "BulletDynamics/

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.

e9b21e21a6 Pathnames between #include files that are intended to be used within application code should not depend on the paths to the subdirectories being known to the compiler because this will not always be the case when an end-user includes your headers.
Includes of files in the local hierarchy must not use <...> please stick with "..."

2b1657b1dd Refactoring: another huge number of changes, renamed methods to start with lower-case. 2006-09-28 01:11:16 +00:00

eb23bb5c0c merged most of the changes from the branch into trunk, except for COLLADA, libxml and glut glitches.
Still need to verify to make sure no unwanted renaming is introduced.

0e04cfc806 First stage in refactoring Bullet: moved Bullet Collision and Dynamics and LinearMath into src folder, and all files in Collision Detection and Dynamics have bt prefix.
Made all buildsystems to work again (jam, msvc, cmake)
