ODE CHANGELOG ------------- the rules for this file: * entries are sorted newest-first. * summarize sets of changes - dont reproduce every CVS log comment here. * don't ever delete anything. * keep the format consistent (79 char width, M/D/Y date format). ------------------------------------------------------------------------------ 11/12/2018 Oleh Derevenko * The commentary from 11/05/2018 was wrong. The constraints were not reset to their natural order and remained randomized. The other thing that was missing was full contraint reorder without separation into independent and dependent ones. The algorithm doesn't converge without it well. 11/10/2018 Oleh Derevenko * An incorrect optimization to Jacobian Copy building code from #1938 that resulted in corrupt data in multi-threaded execution mode was fixed. 11/05/2018 Oleh Derevenko * An unintended change from commit #1898 has been reverted. The QuickStep used to solve with randomized constraint order each 8th iteration. The other iterations, the constraints were reset to their natural order, as generated, with the dependent constraints gathered in reverse order at end (the reverse order is somehow important). With the commit #1898 the constraints were randomly reordered each 8th iteration but then remained in that randomized order and only were re-randomized on subsequent multiples of 8. 10/09/2017 Markus Rickert * CMake support for project file generation has been added. 06/14/2017 Oleh Derevenko * dxHashSpace::collide() has been changed to fault host program if scene gets too large and causes integer overflow. 06/06/2017 Oleh Derevenko * Memory and pointer size integer type use has been changed so that internal typedefs are used instead of "_t" suffixed types. 05/09/2017 Oleh Derevenko * Introduction of cooperative algorithms API. L*D*LT cooperative factorization and linear equation system cooperative solving have been implemented. * AtomicReadReorderBarrier, AtomicStore, AtomicStorePointer functions have been added and some atomic function implementations have been improved in OU. 02/20/2017 Oleh Derevenko * Project generation options have been changed to have built-in multithreaded threading implementation enabled by default. 02/19/2017 Oleh Derevenko * dWorldStep threaded implementation has been extended to the final steps of constraint force applications and body position updates after the LCP solving. Note that body callbacks (if set) may be called from multiple threads if threaded execution is enabled. * OU atomicord32 type has been fixed to be unsigned on all supported platforms. 01/09/2017 Oleh Derevenko * dGeomTriMeshDataPreprocess2() public function has been added to replace dGeomTriMeshDataPreprocess(). Face angles pre-computation for triangle meshes has been implemented. 11/13/2016 Oleh Derevenko * dGeomTriMeshDataGetBuff and dGeomTriMeshDataSetBuff have been marked deprecated and their functionality implemented via dGeomTriMeshDataGet and dGeomTriMeshDataSet. Extra function variant dGeomTriMeshDataGet2() has been added to allow returning data size. 11/07/2016 Oleh Derevenko * The implementation of OPCODE TriMesh data pre-processing (dGeomTriMeshDataPreprocess()) has been optimized to only contain a sort and a single pass over edges (used to be a sort and O(N^2)). 10/29/2016 Oleh Derevenko * dGeomTriMeshDataPreprocess() public function has been changed to return a boolean status (it can fail in low memory conditions). 07/10/2016 Oleh Derevenko * The correct handling of dJOINT_REVERSE mode for AngularMotor Joint implemented (issue #37). 06/29/2016 Oleh Derevenko * A bug fixed with HashSpace calling big boxes collision twice (both straight and reverse geometries order) since revision #1831. 06/03/2016 Oleh Derevenko * dJointSetHinge2Axes public function has been added and dJointSetHinge2Axis1/2 have been marked deprecated due to being unsafe. 05/13/2016 Oleh Derevenko * ICE Container class allocation strategy fixed to avoid reserving excess memory with large collections. 05/10/2016 Oleh Derevenko * dSafeNormalize3 and dSafeNormalize4 functions changed to leave the parameter intact instead of replacing it with the X-axis unit in case of fault. 04/12/2016 Oleh Derevenko * A function to create a self-threaded threading implementation object has been moved back to public headers as there could be a use for it while running several worlds in parallel threads. 01/09/2016 Oleh Derevenko * Hinge2 joint corected to avoid faulting asserts when the axes get temporarily invalid during assignments (suggested by David Mansolino) 01/03/2016 Oleh Derevenko * An invalid memory access fixed in dxSAPSpace::BoxPruning() in case if there were NaN values in AABBs to be sorted. 12/25/2015 Oleh Derevenko * Unexpected joint mode assignment (instead of comparison) fixed within an dUASSERT in dJointSetTransmissionAxis2() of transmission joint 11/28/2015 Oleh Derevenko * Convex-Trimesh collider added (libccd+GIMPACT only)(by Piotr Piastucki) * dCreateConvex() and dGeomSetConvex() public APIs changed to expect their parameter arrays as const pointers 11/01/2015 Oleh Derevenko * OPCODE mesh colliders' input coordinates have been offset to mesh-relative frames to decrease potential computational errors (suggested by luckytrashsc2@g***l.com) 08/05/2015 Oleh Derevenko * Implemented change to return highest depth contacts subset for GIMPACT in cases if contacts count exceeds requested maximum (as suggested in the issue #36 by Piotr Piastucki) 11/17/2014 Daniel K. O. * Added support for using libccd from the system (if found via pkg-config) 11/10/2014 Oleh Derevenko * Floating point division by zero in capsule-ray collision routine in case if the ray axis was parallel the cylinder and the ray started from within it fixed (issue #26) 11/08/2014 Oleh Derevenko * Threading support has been extended to complete implementation of QuickStep 10/29/2014 Daniel K. O. * Added dJointSetDBallDistance 10/19/2014 Oleh Derevenko * Built-in threading implementation compilation fixed for OSX (clock_gettime() is missing from the system - reported by Bram) 08/10/2014 Oleh Derevenko * Declarations of dWorld[Get/Set]AutoDisableLinearAverageThreshold and dWorld[Get/Set]AutoDisableAngularAverageThreshold have been removed from public headers (were orphaned since rev.1052) 07/16/2014 Oleh Derevenko * Two fixes by Francesco Cat applied (fixes for mistakes made during code style improvements in the past) 02/27/14 Daniel K. O. * Added dODE_VERSION macro to public headers (issue #24). 02/11/14 Daniel K. O. * Added dJointGetHinge2Angle2 (issue #12). 02/07/14 Daniel K.

O. * Fixed cylinder AABB computation. 01/25/14 Daniel K. O. * Removed ALLOCA calls from dHashSpace; it should not depend on stack size limits anymore. 12/06/13 Daniel K. O. * Applied patch #181: fix some bugs in AMotor joint. * Applied patch #186: fix some bugs in PU joint. * Applied patch #182: Transmission joint. * Applied patch #184: implement rolling friction for contacts. 08/08/13 Oleh Derevenko * Joint feedback forces application fixed in QuickStep implementation (was broken since revision #1919 in old repository (#1927 in new one)) 08/04/13 Oleh Derevenko * Bugfix #89 by Luc applied (dJointAddSliderForce() adds a zero force when the parent body is NULL) 05/18/13 Oleh Derevenko * OU library has been included in ODE at revision #46 instead of being used as an external link due to difficulties using external references with new protocol used for storage at SF. 03/03/13 Oleh Derevenko * Fixed issue with "findex==-1" constraints being intermixed with "findex!=-1" ones during constraints random reordering in QuickStep. 02/03/13 Oleh Derevenko * [u]int[8/16/32] renamed to contain "d" prefix so that global namespace was not polluted with these names unconditionally. If your project depended on these types other than just for passing parameters to ODE calls, add similar typedefs for yourself in some of your project's global headers. 01/02/13 Oleh Derevenko * Applied patch #183 by Joseph Cooper (complementary matrix calculation fix). 12/28/12 Oleh Derevenko * A bug with heightfield data assigned to a wrong field in dGeomHeightfieldSetHeightfieldData fixed (bug report #88 by Luc). 12/18/12 Oleh Derevenko * Fixed issue with some kinds of joints (Ball, DBall, DHinge, Fixed) might overwrite world ERP value with their custom ERP during getInfo2() call and that inappropriate value would then be passed to subsequent joints in solver instead of world ERP. 12/01/12 Oleh Derevenko * Fixed issues reported in patches #151 and #22 (collisions with SAPSpace and QuadTreeSpace might not work because geometries list was misused in them). * Applied patch #160 "IsPointInPolygon in convex.cpp returns wrong results" (by Janis Rucis) 11/25/12 Oleh Derevenko * Configuration option --disable-threading-intf added (--no-threading-intf for Windows/Premake). This allows disabling threading interface support (external implementations may not be assigned) but eliminates dependency on OU and use of atomics in steppers. 11/05/12 Oleh Derevenko * Fixed zero comparisons in OPCODE to use relative error instead of absolute epsilon value (found by Bill Sellers) 06/08/12 Daniel K. O. * Removed the need for defining dSINGLE/dDOUBLE; this is stored now in the generated ode/precision.h header. * Some code cleanup to get rid of GCC warnings. 05/30/12 Daniel K.

O. * Applied patch from bug #3431829 - better handling of capsule-box with deep penetrations. * Fixed zero-mu issues: now either mu or mu2 can be set to zero. 03/17/12 Oleh Derevenko * Threaded execution support interface added. Optional built-in threading implementation added. Internal threading implementation is excluded by default and to be used, it must be enabled with configure/premake. At present, if threading interface is assigned to a world, island selection and stepping is performed in multiple threads (one thread per island). 03/12/12 Oleh Derevenko * PURE_INLINE macro renamed to ODE_PURE_INLINE and definition of dNextAfter()/dCopySign() corrected to avoid creating conflicts with other libraries. 02/03/12 Oleh Derevenko * Assertion checking macros moved from common.h to error.h 12/18/11 Oleh Derevenko * dIVERIFY macro added (same as dIASSERT in debug mode but evaluates its expression in release mode) to be used to assert variable value which is not used further in text while avoiding compiler warning. * dICHECK macro added (same as dIASSERT but evaluates its expression and raises assertion fault regardless of compilation mode) to be used to generate a fault in cases when error is very unlikely but must be handled and handling is very troublesome (e.g. failure to lock a mutex due to lack of resources). 12/07/11 Oleh Derevenko * Partially fixed size_t to integer conversion warnings * Fixed type signedness and added casts to size_t wherever necessary in Step/QuickStep 11/04/11 Daniel K. O. * Applied patch #3429454 - fix compilation on some platforms. 10/28/11 Daniel K. O. * Fixed a box-capsule bug: more reasonable normal for deep penetrations (contributed by Georg Martius.) 10/27/11 Daniel K.

O. * Added python bindings, contributed by Gideon Klompje. * Updated some build scripts. * Changed spheres distribution in demo_space_stress. 05/17/11 Oleh Derevenko * A typo in step.cpp fixed (assignment operator in a conditional instead of comparison) (reported by Bram Stolk) 01/29/11 Oleh Derevenko * Heightfield zone boundaries calculation code fixed to also consider whole next cell after the AABB if the AABB ends exactly at the cell boundary. 01/23/11 Daniel K. O. * Applied patch from Daniel Fiser, add libccd collider for box-cylinder. 01/20/11 Daniel K. O. * Applied patch from Daniel Fiser, fix infinite loop in libccd caused by numerical problems. 01/06/11 Daniel K.

Daniel K. O. * Applied patch #2991622: dGeomGetRelPointPos, dGeomGetPosRelPoint, dGeomVectorToWorld, and dGeomVectorFromWorld. 07/16/10 Daniel K. O. * Fixed bug #2937076: don't try to build demos if drawstuff is disabled. 05/02/10 Oleh Derevenko * Missing extern "C" wrapper has been added to include/ode/export-dif.h (reported by Danny Price). The change affects dWorldExportDIF() public function. 05/02/10 Oleh Derevenko * Patch applied (#2995450) to generate up to four contacts for box- plane collision test (by alexdu) and fix contact depths. 05/02/10 Oleh Derevenko * dGeomLowLevelControl function added with ability to change/query OPCODE trimesh-sphere contact merging behavior at runtime. 02/18/10 Daniel K. O. * Fixed bug affecting disabled joints and dWorldStep. 01/16/10 Oleh Derevenko * Patch applied (#2931174) to make demos work for recent MacOS. * Patch applied (#2931177) to fix the demos' framerate on X11. 12/20/09 Oleh Derevenko * QuadTreeSpace implementation corrected to avoid object-block relation ambiguity due to numeric errors. 12/04/09 Oleh Derevenko * odecpp classes changed to be inheritable and easily expandable 11/29/09 Oleh Derevenko * Improvement for trimesh-plane collision (also used in trimesh-heightfield) to exclude mesh vertices that have already generated contacts from further examination and contact generation in other triangles (suggested by LR). 10/25/09 Oleh Derevenko * Macros changed to static inline functions in odemath.h and related files. Some code duplication has been eliminated across the files. * Fixed handling of --disable-asserts and --enable-double-precision (absence of --enable-double-precision) in configure script. The script was not appending compiler defines correctly. * dWorldStep implementation changed to remove allocation on stack. dUSE_MALLOC_FOR_ALLOCA define has been removed as well as corresponding configuration parameter. Also dMemoryFlag public variable has been removed. (look for presence of ODE_EXT_malloc_not_alloca configuration string if your application is dependent on that variable). 09/05/09 Oleh Derevenko * dWorldStepFast1 API removed along with dWorld[Get/Set]AutoEnableDepthSF1 08/29/09 Oleh Derevenko * Fixed uninitialized floating point array used in computations. 08/12/09 Oleh Derevenko * A typo fixed in dGeomCopyOffsetRotation() (final_posr was used instead of offset_posr). Reported by Tilmann. 08/11/09 Daniel K. O. * Made sure neither dSINGLE or dDOUBLE is defined by default; the user should always explicitly specify the precision. 06/27/09 Oleh Derevenko * New functions have been added: - dWorldUseSharedWorkingMemory - dWorldCleanupWorkingMemory - dWorldSetStepMemoryReservationPolicy - dWorldSetStepMemoryManager 06/25/09 Remi Ricard (papaDoc) * Add limit to the to the second axis of the universal joint for the pu joint. 06/14/09 Oleh Derevenko * dWorldQuickStep re-implemented to avoid memory allocation on stack. Also several optimizations have been made to decrease memory requirements and optimize algorithm implementation of dWorldQuickStep. dWorldStep still remains with old memory allocation however new APIs mentioned below are fully functional for it. Both dWorldStep and dWorldQuickStep have been changed to return boolean success status. * dInitODE2() changed to automatically call AllocateODEDataForThread(dAllocateFlagBasicData) after library initialization as this is a required initialization minimum that must always be performed anyway. 06/05/09 Daniel K. O. * Removed aliasing issues from OPCODE/Ice, plus some other warnings. Now it builds on gcc 4.3.2 with '-Wall -Werror -O3". 05/30/09 Oleh Derevenko * A minor memory usage optimization for QuickStep. 05/24/09 Daniel K. O. * Made the new trimesh collider the default. * Added a "-texturepath" option to drawstuff. 05/18/09 Oleh Derevenko * Heightfield rotation fixed to avoid NaNs while rotating infinite MIN/MAX heights. 05/03/09 Oleh Derevenko * Incorrect parameter order fixed on contact merging in Sphere-Trimesh collisions. The bug resulted in merged contact remaining with normal of first contact found. Thanks to Dimitris Papavasiliou for reporting. 04/23/09 Daniel K. O. * Fixed bug #2685170: use the C99 __func__ instead of __FUNCTION__ when a C99 implementation is available. 04/07/09 Remi Ricard (papaDoc) * Remove unused code in demo_joints.cpp, reported by Tilmann. 04/07/09 Remi Ricard (papaDoc) * Fix bug in collision categories in demo_jointPU, reported by Tilmann 03/14/09 Oleh Derevenko * A possibility to initialize/close ODE multiple times recursively has been added. Also, now a call to dSpaceSetManualCleanup() is required for each space right after creation if ODE has been initialized in thread data manual cleanup mode. 03/07/09 Oleh Derevenko * Thread local data has been cleaned up from OPCODE and OdeTls as it is not used (OPC_SweepAndPrune.* and OPC_BoxPruning.* have been removed - rebuilding project files is necessary). 02/07/09 Daniel K. O. * New house of cards demo, which stresses the friction handling stability. 01/29/09 Remi Ricard (papaDoc) * Fix bug: Fix problem when attaching no body to a joint. Before calling setRelativeValues a check is made for bodies. * Add unittest 01/28/09 Daniel K. O. * Applied patch #2538046: Heightfield AABB bounds patch. 01/23/09 Remi Ricard (papaDoc) * Add new function dJointSetUniversalAxis1Offset and dJointSetUniversalAxis2Offset * Add unittest for those funcitons. 01/23/09 Remi Ricard (papaDoc) * Fix problem with dJointGetUniversalAngle2 when the joint is attached to only a body 2. The sign was inverted. * Add unit test to verify for this problem 01/21/09 Remi Ricard (papaDoc) * Fix bug reported by Tilman: dxJointPU::getInfo1 was setting twice the limit of limot1 to zero and not limot2 01/17/09 Daniel K. O. * Fixed a bug in dSpaceCollide2: if both geoms are not in spaces they would not have valid AABBs. 12/20/08 Daniel K. O. * New functions: dJointEnable, dJointDisable, dJointIsEnabled (patch #2454764). 12/19/08 Daniel K. O. * Removed inline asm statements that break builds on 64-bit VC++. 12/09/08 Daniel K. O. * Applied patch #2381592, which adds support for Kinematic Bodies. 12/06/08 Oleh Derevenko * Applied a patch by Martijn Buijs to make GIMPACT trimesh-ray collisions to be consistent with those in OPCODE. * Swapped geometries returned in contacts for OPCODE Trimesh-Plane collisions as they were returned in unnatural order being different from that in GIMPACT * Applied a patch by Martijn Buijs to make side1, side2 fields of contact structure be always initialized, either with -1 for non-trmesh geometries or with triangle index for trimeshes. These fields were only assigned for trimesh-trimesh collisions before. * dGeomTriMeshSetTriMergeCallback/dGeomTriMeshGetTriMergeCallback API added to set/get user defined callback procedure for trimeshes that would be invoked when contacts are merged to let user code accumulate attributes of original contact triangles and generate a fake index by which it would later be able to determine those attributes. If the callback is not assigned (the default) -1 is generated as triangle index for merged contacts (there was an index of first of merged triangles before!!!). The callback is currently used within OPCODE trimesh-sphere and OPCODE new trimesh-trimesh collisions. 11/20/08 Remi Ricard (papaDoc) * Fix problem with dJointGetPUPosition and dJointGetPUPositionRate when the joint is attached to only a body 2. The sign was inverted. * Fix bug: When a pu joint had only one body attached to position 2, dJointAttach(jId, 0, bId). The body was not push in the right direction to move back between the limits. * Add unit test to check the above problem * Add the function void dJointSetPUAnchorOffset * Make the function void dJointSetPUAnchorDelta deprecated 11/19/08 Remi Ricard (papaDoc) * Fix bug: When a pr joint had only one body attached to position 2, dJointAttach(jId, 0, bId).

Now is possible to set bigger sleeping threshold values and objects won't be sleeping on the air. They will rest on the floor properly. * dInitODE function added. * Is Obligatory to call dInitODE() at the beginning for initialize ODE, and calling dCloseODE() when the program ends. 09/20/06 bram * Fixed two bugs in cyl/plane collision test. 09/13/06 Remi * New Rotoide - Prismatic joint type * dJointGetUniversalAngles for efficient angle retrieval. 08/09/06 david * Integrated plane2d joint type which constrains bodies to z == 0. 07/06/06 david * Added heightfield primitive collision code. Simple test available in ode/test/test_heightfield 04/03/06 rodrigo * Added Convex primitive collision code, currently only convex-sphere and convex-plane work 04/01/06 bram * Added program to test trimesh vs sphere: ode/test/test_basket 03/20/06 jason379 * Added new autogenerated Visual Studio projects, with Premake scripts 03/17/06 bram * Added plane/cyl intersection test * Renamed CCylinder to Capsule 02/04/06 gcarlton * Added support for geom offsets. 10/26/05 rodrigo * Removed LIBTOOL from autotools since it was not really required. * Added a target to build ODE as a shared library, this shared library gets build alongside the static one, no flags required. 10/24/05 tfautre (Backported patches from STABLE branch, applied by Adam) * dRandInt changed for a non-double all-int version. * mics minor fixes and improvements. 04/05/05 tfautre * Fixed segmentation fault with OPCODE on 64 bits systems. 03/31/05 tfautre * Fixed timer.cpp compiler error on x86-64 using GCC. 03/29/05 colin * Added trimesh preprocessing to mark unneeded edges and verts. Also added support for preprocessed info to the ccylinder-trimesh collider. 12/07/04 adam * Important AMotors bugfix 09/22/04 jeff * Assorted small bugfixes and tweaks for trimesh_{box,ccylinder,trimesh} collisions 09/21/04 jeff * added functions to joint.cpp to allow joint attachment to moving geoms. * added malloc-based memory allocation in step.cpp & lcp.cpp (turned on with a #define switch in common.h) 05/29/04 russ * added joint feedback to the QuickStep solver 05/18/04 russ * added warm starting to the QuickStep solver 05/18/04 russ * added the QuickStep solver * added contact parameter functions. 05/05/04 adam * use dRandInt instead of rand() in stepfast. 04/21/04 russ * added auto-disable support from Aras Pranckevicius (with modifications by russ). this useful feature can speed up simulation significantly in some cases. * various internal tidyups. 04/20/04 russ * changed the meaning of the 'index' argument to dJointGetBody(): it was the only remaining API function that does not respect dJOINT_REVERSE (spotted by Matthew D. Hancher). * updated the C++ headers: fixed two minor bugs and added support for dQuadTreeSpace, dRay, and the dGeom::getSpace() method (from Matthew D. Hancher). 04/18/04 russ * changed the way that the dInfinity constant is implemented: now it is #defined to be one of: FLT_MAX, DBL_MAX, HUGE_VAL, HUGE_VALF, or a large numeric constant. previously it was a variable that was exported from the library. this simplifies the configuration and build process quite a bit, especially in the case of DLLs. * removed the old, deprecated collision system (geom.cpp,space.cpp, geom.h,space.h,odecpp_old_collision.h). the ODE_OLD_COLLISION configuration setting no longer has any meaning. * removed support for dGeomGroups, which have been deprecated for a while and are equivalent to 'spaces' anyway. 04/13/04 russ * bug fix in dMassSetCappedCylinder(), from Matthew D. Hancher. 04/08/04 russ * added trimesh-CCylinder capability, from Vadim Macagon . 04/04/04 adam * yet another rewrite of triangle-box collision code, this time based on code donated by Croteam, ported by asko@jetti.org and tweaked by Erwin. 04/04/04 adam * merged trimesh-trimesh collision code by Jeffrey Smith . * changed it to not break the trimesh interface, fix some GCC compilation problems, bring it up to date with ODE changes from 2003-11-15 -> 2004-04-04. * add ability to drop meshes on meshes in test_moving_trimesh, not as good as it could be but it's illustrative. 01/16/04 adam * implement a bunch of ultra-simple TriMesh functions that were in the headers but not in the code -- patch by Vadim Macagon * disable temporal coherence on trimeshes by default, since it has scaleability issues that don't make it a general clear win. 12/01/03 adam * implement dxHashSpace::collide2(), not particularly efficiently. 11/14/03 adam * applied several Trimesh fixes and improvements from Aras Pranckevicius 10/22/03 adam * apply Nguyen Binh's work for removing many dSetZero() calls and some other extraneous initializations. 07/29/03 martin * added dJointAdd*Torque/Force(). 07/10/03 russ * added the StepFast code, by David Whittaker. 07/02/03 martin * added dMassSet*Total(). 07/01/03 martin * added joint limits and motors to universal joints. * reversed the polarity of the dJOINT_REVERSE flag. 06/30/03 russ * added the TriMesh geom class and the quad tree space to the ODE core. both of these were developed by Erwin de Vries. added OPCODE to the ODE distribution, this is required by TriMesh. 06/23/03 martin * added dGeomSetQuaternion() and dGeomGetQuaternion() * added dJointGet*Anchor2() 05/07/03 russ * added dGeomGetSpace(). 02/05/03 russ * added dMassSetCylinder(). 12/07/02 russ * added dAreConnectedExcluding(). 11/30/02 russ * added the ray geom class. * added the dGeomXXXPointDepth() functions. * added a collision test infrastructure, and some more tests. 11/24/02 russ * added support for multiple box-box contacts. 11/10/02 russ * added new collision system. select between the old/new system by setting the ODE_OLD_COLLISION variable in config/user-settings. 10/28/02 russ * fixed two problems in the LCP code to improve the reliability of the dContactApprox1 contact mode. * added a FAQ question about rolling bodies getting stuck when they hit multiple geoms. 09/08/02 russ * added dClosestLineSegmentPoints(). * implemented dCollideCB(). 08/28/02 russ * added dJointSetFeedback() and dJointGetFeedback(). 08/05/02 russ * added dGeomTransformSetInfo() and dGeomTransformGetInfo(). 07/13/02 russ * added dBodySetForce(), dBodySetTorque(), dWorldImpulseToForce(), dBodyGetPosRelPoint(), dBodyGetPosRelPoint(), dBodyVectorToWorld(), dBodyVectorFromWorld(). * added dBodyGetPointVel() (thanks to Colin Reed). * added a new C++ interface (from Martin C. Martin, with modifications by russ). the old C++ interface is now in odecpp_old.h. 06/25/02 russ * added an additional BSD-style licensing option for ODE. 06/23/02 russ * added dCloseODE(), contributed by Nate Waddoups and David McClurg. 05/16/02 russ * added dSpaceQuery(), contributed by Nate Waddoups. 04/07/02 russ * added a section to the documentation for universal joints. this includes a picture of the joint. 04/05/02 russ * added a universal joint class (generously contributed by Martin C. Martin). it doesn't (yet) have a motor or joint limits, but it does come with tests. 03/11/02 russ * makefile changes to accomodate OSs with command line length limitations (thanks to Norman Lin). 01/06/02 russ * added the dBodySetGravityMode() and dBodyGetGravityMode() functions, which change the dxBodyNoGravity body flag. * added support for building a DLL with MSVC - there is now a msvc-dll target. thanks to Norman Lin for doing this. 12/28/01 russ * added the dParamCFM joint parameter. 12/24/01 russ * reworked the build system to make it more cross-platform. there is now a single top-level makefile and a configurator.c program. see the INSTALL file for details. 12/04/01 russ * the "angular motor" joint has been completed, and a new section has been added to the documentation. 11/26/01 russ * added a new joint type: "angular motor". using this joint is a good way to get ball-joint motors and limits. this is work in progress - it has not been fully implemented or tested yet. 11/22/01 russ * replaced the mmap()-based joint group stack (stack.cpp) with a malloc()-based arena stack (obstack.cpp). this will be more portable and should not impact performance. 11/12/01 russ * changed the meaning of the 'flags' parameter to dCollide() and related functions: now the size of the contact buffer is kept in the lower 16 bits. this change will be backward compatible. * added dBodyGetFiniteRotationMode() and dBodyGetFiniteRotationAxis(). * added dBodyAddForceAtRelPos() function. 11/11/01 russ * added the ability to manually enable and disable bodies. see dBodyEnable(), dBodyDisable(), dBodyIsEnabled(). * fixed a potential bug: when a world is destroyed that contains joints in joint groups, those joints are marked as "deactivated" in the joint group, so when the joint group is destroyed they can be ignored. * the test_boxstack demo has new options to enable and disable bodies. * new configuration parameter in config.h: dEFFICIENT_SIZE. 11/11/01 russ * started the change log for ODE. changes older than today were added to this file by inspecting the CVS logs. 11/05/01 russ * added REAL() constructions for floating point numbers, to prevent many warnings when compiling under VC++. 11/03/01 russ * added geometry transform class, documented composite objects. * added collision rule: no contacts if both geoms on the same body. this is not the best rule, may have to remove this in the future. * new dMassAdd() function. * capped cylinder to capped cylinder collision function. 10/31/01 russ * increase CFM in some demos to make them more robust. 10/29/01 russ * added new accessor functions. 10/19/01 russ * added the dJOINT_TWOBODIES flag to the joint, that says it can not be attached to just one body. 10/12/01 russ * fixed a collision bug in dCollide() that was causing memory corruption when multiple contacts were being returned. 10/11/01 russ * joints can now return m=0 to be "inactive". added a "null" joint to test this. 10/09/01 russ * in the LCP solver, try to fail gracefully when s <= 0. * dAABBTestFn() API change. 10/08/01 russ * fixed a contact swapping bug in dCollide(). 10/07/01 russ * added capped cylinder geometry object. 09/30/01 russ * the test_buggy demo now uses geometry groups. * added a dAABBTestFn field in the geometry classes. 09/29/01 russ * added geometry groups. 09/20/01 russ * added finite rotation stuff.
