42278e58dd fixes to add improved double-precision for raycasts 2007-02-14 04:10:55 +00:00

581468ceec Added btCapsuleShape. This could already be simulated by simply adding 2 spheres to the btMultiSphereShape, but this was bad documented/unknown.
For tapered capsules, you can still use btMultiSphereShape, just pass 2 spheres with different radius.

ca973e9322 Fixed AABB tree building, which failed for certain large triangle meshes due to stack overflow.
Now it has a safer check for unbalanced tree, and forces them to be balanced.

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 "..."

208bbe7594 Added a set of empty, classless 'extern "C"' probe functions to allow '.so' loaders and application domain 'autotools' to easily and unambiguously check for the correct installation of the various bullet libraries.
eg:

  bulletmath_suffix="-lbulletmath"
  bulletcollision_suffix="-lbulletcollision"
  bulletdynamics_suffix="-lbulletdynamics"
  dnl Check bulletmath library
  AC_CHECK_LIB(bulletmath, btBulletMathProbe, true,
  AC_MSG_ERROR([there seems to be a problem with the bulletmath library]))
  LIBS="$bulletmath_suffix $LIBS"
  dnl Check bulletcollision library
  AC_CHECK_LIB(bulletcollision, btBulletCollisionProbe, true,
  AC_MSG_ERROR([there seems to be a problem with the bulletcollision library]))
  LIBS="$bulletcollision_suffix $LIBS"
  dnl Check bulletdynamics library
  AC_CHECK_LIB(bulletdynamics, btBulletDynamicsProbe, true,
  AC_MSG_ERROR([there seems to be a problem with the bulletdynamics library]))
  LIBS="$bulletdynamics_suffix $LIBS"

bf591b44ec Replaced most STL std::vector with btAlignedObjectArray.
Same interface but less features (push_back, pop_back, clear, size, [] etc).
To prepare for SIMD/SSE code: Added 		#define ATTRIBUTE_ALIGNED16(a) __declspec(align(16)) a

b6d1b4c94e Added btNearCallback. This is similar to Open Dynamics Engine (ODE) dNearCallback, but important differences:
- contact points are persistent (lifetime more then one frame, for warmstarting/incremental contact point management)
- continuous collision detection, time of impact
Added btRigidBody::isInWorld(), returns true if btRigidBody is inside a btCollisionWorld/btDynamicsWorld derived class
Added angularFactor to btRigidbody, this helps some character control (no angular impulse applied)

6738ed329d ASSERT -> btAssert
Added btStackAlloc to Bullet (right now only used by btGjkEpa)
removed default constructors of btCollisionWorld/btDiscreteDynamicsWorld, to reduce link-time dependencies

2a1546764e perform GJK calculations in local space, transform added contact points back into worldspace.
Perhaps rethink of adding contact points in local place (might hit complication with compounds)

4050da0e2f One of the last parts of the refactoring (hopefully), made most members of btCollisionObject protected.

dd8297c86e refresh contact points, even when they are already persistent. needs a bit more work (a 'replacedContactCallback' where optionally the user can carry over the persistent contact data) 2006-10-30 04:51:17 +00:00

3fe3b11924 use Dispatcher in ConcaveConvexCollisionAlgorithm (so it uses the registered collision algorithm, not hardcoded convexconcave)
improved performance of constraint solver by precalculating the cross product/impulse arm
added collision comparison code: ODE box-box, also sphere-triangle
added safety check into GJK, and an assert for AABB's that are very large
write partid/triangle index outside of GJK
