296 be consistent with those in OPCODE.
297 * Swapped geometries returned in contacts for OPCODE Trimesh-Plane collisions
298 as they were returned in unnatural order being different from that in GIMPACT
299 * Applied a patch by Martijn Buijs to make side1, side2 fields of contact
300 structure be always initialized, either with -1 for non-trmesh geometries
301 or with triangle index for trimeshes. These fields were only assigned for
302 trimesh-trimesh collisions before.
303 * dGeomTriMeshSetTriMergeCallback/dGeomTriMeshGetTriMergeCallback API added
304 to set/get user defined callback procedure for trimeshes that would be
305 invoked when contacts are merged to let user code accumulate attributes of
306 original contact triangles and generate a fake index by which it would
307 later be able to determine those attributes. If the callback is not
308 assigned (the default) -1 is generated as triangle index for merged
309 contacts (there was an index of first of merged triangles before!!!).
310 The callback is currently used within OPCODE trimesh-sphere and OPCODE
311 new trimesh-trimesh collisions.

704 * added warm starting to the QuickStep solver
708 * added the QuickStep solver
710 * added contact parameter functions.
714 * use dRandInt instead of rand() in stepfast.
718 * added auto-disable support from Aras Pranckevicius (with
719 modifications by russ). this useful feature can speed up
720 simulation significantly in some cases.
722 * various internal tidyups.
726 * changed the meaning of the 'index' argument to dJointGetBody():
727 it was the only remaining API function that does not respect
728 dJOINT_REVERSE (spotted by Matthew D. Hancher).
730 * updated the C++ headers: fixed two minor bugs and added
731 support for dQuadTreeSpace, dRay, and the dGeom::getSpace() method
732 (from Matthew D. Hancher).
736 * changed the way that the dInfinity constant is implemented: now it
737 is #defined to be one of: FLT_MAX, DBL_MAX, HUGE_VAL, HUGE_VALF, or
738 a large numeric constant. previously it was a variable that was
739 exported from the library. this simplifies the configuration and
740 build process quite a bit, especially in the case of DLLs.
742 * removed the old, deprecated collision system (geom.cpp,space.cpp,
743 geom.h,space.h,odecpp_old_collision.h). the ODE_OLD_COLLISION
744 configuration setting no longer has any meaning.
746 * removed support for dGeomGroups, which have been deprecated for
747 a while and are equivalent to 'spaces' anyway.
751 * bug fix in dMassSetCappedCylinder(), from Matthew D. Hancher.
755 * added trimesh-CCylinder capability, from Vadim Macagon
756 <vadim_mcagon@hotmail.com>.
760 * yet another rewrite of triangle-box collision code, this
761 time based on code donated by Croteam, ported by asko@jetti.org
762 and tweaked by Erwin.
766 * merged trimesh-trimesh collision code by
767 Jeffrey Smith <jeffreys@Softimage.com>.
769 * changed it to not break the trimesh interface, fix
770 some GCC compilation problems, bring it up to date with
771 ODE changes from 2003-11-15 -> 2004-04-04.
773 * add ability to drop meshes on meshes in test_moving_trimesh,
774 not as good as it could be but it's illustrative.
778 * implement a bunch of ultra-simple TriMesh functions that were
779 in the headers but not in the code -- patch by
780 Vadim Macagon <vadim_mcagon@hotmail.com>
782 * disable temporal coherence on trimeshes by default, since
783 it has scaleability issues that don't make it a general clear win.
787 * implement dxHashSpace::collide2(), not particularly efficiently.
791 * applied several Trimesh fixes and improvements from
792 Aras Pranckevicius <nearaz@interamotion.com>
796 * apply Nguyen Binh's work for removing many dSetZero() calls
797 and some other extraneous initializations.
801 * added dJointAdd*Torque/Force().
805 * added the StepFast code, by David Whittaker.
809 * added dMassSet*Total().
813 * added joint limits and motors to universal joints.
815 * reversed the polarity of the dJOINT_REVERSE flag.
819 * added the TriMesh geom class and the quad tree space to the ODE
820 core. both of these were developed by Erwin de Vries. added OPCODE
821 to the ODE distribution, this is required by TriMesh.
825 * added dGeomSetQuaternion() and dGeomGetQuaternion()
827 * added dJointGet*Anchor2()
831 * added dGeomGetSpace().
835 * added dMassSetCylinder().
839 * added dAreConnectedExcluding().
843 * added the ray geom class.
845 * added the dGeomXXXPointDepth() functions.
847 * added a collision test infrastructure, and some more tests.
851 * added support for multiple box-box contacts.
855 * added new collision system. select between the old/new system by
856 setting the ODE_OLD_COLLISION variable in config/user-settings.
860 * fixed two problems in the LCP code to improve the reliability of
861 the dContactApprox1 contact mode.
863 * added a FAQ question about rolling bodies getting stuck when they
868 * added dClosestLineSegmentPoints().
869 * implemented dCollideCB().
873 * added dJointSetFeedback() and dJointGetFeedback().
877 * added dGeomTransformSetInfo() and dGeomTransformGetInfo().
881 * added dBodySetForce(), dBodySetTorque(), dWorldImpulseToForce(),
882 dBodyGetPosRelPoint(), dBodyGetPosRelPoint(), dBodyVectorToWorld(),
883 dBodyVectorFromWorld().
885 * added dBodyGetPointVel() (thanks to Colin Reed).
887 * added a new C++ interface (from Martin C. Martin, with modifications
888 by russ). the old C++ interface is now in odecpp_old.h.
892 * added an additional BSD-style licensing option for ODE.
896 * added dCloseODE(), contributed by Nate Waddoups and David McClurg.
900 * added dSpaceQuery(), contributed by Nate Waddoups.
904 * added a section to the documentation for universal joints.
905 this includes a picture of the joint.
909 * added a universal joint class (generously contributed by
910 Martin C. Martin). it doesn't (yet) have a motor or joint limits,
911 but it does come with tests.
915 * makefile changes to accomodate OSs with command line length
916 limitations (thanks to Norman Lin).
920 * added the dBodySetGravityMode() and dBodyGetGravityMode()
921 functions, which change the dxBodyNoGravity body flag.
923 * added support for building a DLL with MSVC - there is now a
924 msvc-dll target. thanks to Norman Lin for doing this.
928 * added the dParamCFM joint parameter.
932 * reworked the build system to make it more cross-platform.
933 there is now a single top-level makefile and a configurator.c
934 program. see the INSTALL file for details.
938 * the "angular motor" joint has been completed, and a new section
939 has been added to the documentation.
943 * added a new joint type: "angular motor". using this joint is a good
944 way to get ball-joint motors and limits. this is work in progress -
945 it has not been fully implemented or tested yet.
949 * replaced the mmap()-based joint group stack (stack.cpp) with a
950 malloc()-based arena stack (obstack.cpp). this will be more
951 portable and should not impact performance.
955 * changed the meaning of the 'flags' parameter to dCollide() and
956 related functions: now the size of the contact buffer is kept in
957 the lower 16 bits. this change will be backward compatible.
959 * added dBodyGetFiniteRotationMode() and dBodyGetFiniteRotationAxis().
961 * added dBodyAddForceAtRelPos() function.
965 * added the ability to manually enable and disable bodies.
966 see dBodyEnable(), dBodyDisable(), dBodyIsEnabled().
968 * fixed a potential bug: when a world is destroyed that contains
969 joints in joint groups, those joints are marked as "deactivated" in
970 the joint group, so when the joint group is destroyed they can be
973 * the test_boxstack demo has new options to enable and disable bodies.
975 * new configuration parameter in config.h: dEFFICIENT_SIZE.
979 * started the change log for ODE. changes older than today were added
980 to this file by inspecting the CVS logs.
984 * added REAL() constructions for floating point numbers, to prevent
985 many warnings when compiling under VC++.
989 * added geometry transform class, documented composite objects.
991 * added collision rule: no contacts if both geoms on the same body.
992 this is not the best rule, may have to remove this in the future.
994 * new dMassAdd() function.
996 * capped cylinder to capped cylinder collision function.
1000 * increase CFM in some demos to make them more robust.
1004 * added new accessor functions.
1008 * added the dJOINT_TWOBODIES flag to the joint, that says it can not
1009 be attached to just one body.
1013 * fixed a collision bug in dCollide() that was causing memory
1014 corruption when multiple contacts were being returned.
1018 * joints can now return m=0 to be "inactive". added a "null" joint
1023 * in the LCP solver, try to fail gracefully when s <= 0.
1025 * dAABBTestFn() API change.
1029 * fixed a contact swapping bug in dCollide().
1033 * added capped cylinder geometry object.
1037 * the test_buggy demo now uses geometry groups.
1039 * added a dAABBTestFn field in the geometry classes.
1043 * added geometry groups.
1047 * added finite rotation stuff.
