34699f6de6 + add option to set pre-tick callback, called at the beginning of each internal simulation step
+ use real-time for soft body demo (using this pre-tick callback)
+ optimize the generation of bending constraints for the special case where the distance is 2

40c73f327c + CMake build system fix under Windows: don't define _WINDOWS to allow Glut console demo to build properly
+ Allow user to enable useConvexConservativeDistanceUtil . Use dynamicsWorld->getDispatchInfo().m_useConvexConservativeDistanceUtil = true;
(see Demos/Benchmarks/Benchmark4 (convex objects falling down)
+ Fix for plane drawing (just wire-frame)
+ Gimpact: use collision margin of 0.07 for demo (because BULLET_TRIANGLE_COLLISION is used)
+ replace dot,cross,distance,angle,triple in btVector3 by btDot, btCross,btDistance,btAngle,btDistance to avoid naming conflicts
+ Some fixes in GJK penetration depth normal direction (broken in a previous commit)
+ fix in calculateDiffAxisAngleQuaternion to make ConvexConservativeDistanceUtil work properly
+ allow debug drawing to debug btContinuousConvexCollision
+ add comment/warning that btTriangleMesh::findOrAddVertex is an internal method, users should use addTriangle instead

459c22e7cb Synchronized changes of Bullet, from Blender.
Added optional flag btSoftBody::appendAnchor(	int node,btRigidBody* body, bool disableCollisionBetweenLinkedBodies=false), to disable collision between soft body and rigid body, when pinned
Added btCollisionObject::setAnisotropicFriction, to scale friction in x,y,z direction.
Added btCollisionObject::setContactProcessingThreshold(float threshold), to avoid collision resolution of contact above a certain distance.
Avoid collisions between static objects (causes the CharacterDemo to assert, when a dynamic object hits character)

5be9f8f301 basic implementation of self-collision for btSoftBody with collision clusters: perform regular soft body versus soft body, but disable collision detection between clusters that are connected/share any node (vertex).
currently self-collision is always enabled for soft bodies that use clusters collision detectoin. to disable, call 'softbody.m_clusterConnectivity.clear' after 'generateClusters(...) call.

85341fee2a fix more places in btSoftBody that assume btRigidBody (it wasn't designed to support btCollisionObject/btGhostObject).
Add another 'findActiveObject'

3c0ca0d931 Fix btSoftBody issue, so it can interact with btCollisionObject and btGhostObject (and not just btRigidBody and btSoftBody)
Thank for the report mi076 http://www.bulletphysics.com/Bullet/phpBB3/viewtopic.php?f=9&t=2823

remove legacy.c from libxml
removed #include <math.h> from btQuadWord.h , it should be centralized in btScalar.h (to allow easier replacement with fastmath.h etc)

b18aa2b375 Some performance improvements and fixes related to btVector3 being aligned on SPU.
btQuantizedBvh has a version number, memory layout might be different now (due to aligned btVector3)
reorganized some data members of some classes, to reduce memory footprint

cac172d422 Use consistent rayFrom/rayTo API for rayTest for btDbvt and btSoftBody, instead of rayCast/collideRAY(origin,direction). This means RayFromToCaster has a fraction [0..1] instead of distance [0..INF]
Renamed collideRay -> rayTest to reflect change to (rayFrom,rayTo) interface.
Re-use btRayAabb2 function from src/LinearMath/btAabbUtil2.h in btDbvt instead of duplicated implementation.

682a0a1b90 fixed btSoftBodyConcaveCollisionAlgorithm, wrong bounding box transformation
added vertex welding option for btTriangleMesh (brute-force slow)
reject appendFace for some degenerate triangles (all 3 vertices/nodes need to be different)
add setVelocity method for btSoftBody

07b577fd86 make debugDrawWorld virtual for btSoftRigidDynamicsWorld
Move btSoftBodyWorldInfo to public, instead of nested, so it can be easier forward declared.
See http://code.google.com/p/bullet/issues/detail?id=78

Add get methods for damping/thresholds, see http://code.google.com/p/bullet/issues/detail?id=77

3ca977e39f Patch by Nathanael Presson: (needs some more work, some of the demos don't show properly (RayCaster, CollisionInterfaceDemo,'g' key is already occupied in ConcaveDemo etc)
btDbvtBroadphase:
- Fixed a performance issues reported by 'reltham'
- Added btDbvtBroadphase::optimize() for people who want good performances right away or don't do dynamics.
- fixed compilation issues when DBVT_BP_PROFILE was set.

btSoftBody:
- Fixed singular matrix issues related to polar decomposition (flat meshes).

DemoApplication:
- Shadows (enable/disable through 'g' or DemoApplication::setShadows(bool)).
- Texture can be enable/disable through 'u'

CDFramework:
- fixed compilation issues.

bd97c5e569 Fixed warnings in Bullet/src core library
Thanks Martijn Reuvers from Two Tribes B.V. (www.twotribes.com) for the patch

To make this work more visible, suppress warnings in external libraries in Extras (COLLADA_DOM, libxml and glui contain many warnings)
Added PreprocessorDefinitions: _CRT_SECURE_NO_DEPRECATE;_CRT_NONSTDC_NO_DEPRECATE to vcproj files
