eaabf1a2c8 Expose btManifoldResult::calculateCombinedRestitution and btManifoldResult::calculateCombinedFriction as static member functions, so it can be reused for speculative contacts
Add speculative contact restitution, but disabled by default, not well tested (btDiscreteDynamicsWorld::setApplySpeculativeContactRestitution)
Add --with-double-precision option to premake build system

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

5907f81774 Add void btCollisionWorld::contactTest(btCollisionObject* colObj, ContactResultCallback& resultCallback);
The user should derive its own class from ContactResultCallback and implement the following callback (similar to the gContactAddedCallback):

virtual	btScalar	addSingleResult(btManifoldPoint& cp,	const btCollisionObject* colObj0,int partId0,int index0,const btCollisionObject* colObj1,int partId1,int index1) = 0;

d67aa861f2 Add support for childshape index for btCompoundShape during ContactAddedCallback,
see example in Bullet/Demos/ConvexDecompositionDemo
Removed some warnings

2162f6663d disable help text by default in AllBulletDemos (text slows down many graphics cards)
improve CollisionDemo.cpp, show multi-contact generation using perturbation
improve ColladaConverter: add hinge/point 2 point constraint conversion support, add btScaledTriangleMeshShape support
Fix Dynamica MayaPlygin: remove 'active' flag, it has to be replaced by mass=0 for active, mass<>0 for passive
Added missing projectfiles
Fixed single-shot contact generation. it is disabled by default to improve performance
Bugfixes for character controller, thanks to John McCutchan for reporting
Constraint solver: better default settings
btDefaultAllocator: aligned allocator uses non-aligned allocator (instead of directly malloc/free)
disable memalign by default, use Bullet's aligned allocator

0754876d77 Calculate multiple contact points (for convex-convex and convex-plane) when less then 3 points exist in the persistent manifold.
Uses the normal pertubation method, described by Gino van den Bergen:  http://www.bulletphysics.com/Bullet/phpBB3/viewtopic.php?f=4&t=288&p=888#p888
Made btRigidBody::getInvInertiaDiagLocal const, thanks to abhikp (http://code.google.com/p/bullet/issues/detail?id=183 )

0405ce278a use size_t instead of int, for allocator
added hashtable based PairManager, thanks Pierre Terdiman and Erin Catto
improved friction in 'cachefriendly' solver
moved 'refreshcontactpoints' into collision detection, instead of solver
avoid linear search for contact manifolds, by storing an index
ignore margin for sphere shape (its entire radius is already margin)
avoid alignment checks in BVH serialization, they don't compile on 64-bit architectures
made 'bomb' box more heavy

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/

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.

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 "..."

df9230327c Contribution to add optional double precision floating point support. Define BT_USE_DOUBLE_PRECISION for all involved libraries/apps. 2006-12-16 05:51:30 +00:00

4050da0e2f One of the last parts of the refactoring (hopefully), made most members of btCollisionObject protected.
Also did some work on improving the constraint solver.

bf847b839a another large series of changes, related to the refactoring.
CompoundShapes are tricky to manage with respect to persistent contact points and swapped order of btCollisionObjects,
During dispatch, finding an algorith etc. order can be swapped.
fixed several other issues, related to SimpleBroadphase (removing a proxy was not working)

21482e4cab some minor comment-renames, and moved some data from box/sphere into common convex. 2006-09-28 20:14:10 +00:00

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)
