Robert. -- ChangeLog since 2.7.3 2008-10-29 11:51 +0000 [r9077] robert: * From Blasius Czink, "changed the CHECK_CXX_SOURCE_RUNS macro slightly to avoid the compile problems due to bugged "intrin.h". In such a case the mutex fallback will be used (see attached file)." 2008-10-29 11:15 +0000 [r9076] robert: * Warning fixes 2008-10-29 11:09 +0000 [r9075] robert: * Added missing implementations 2008-10-29 10:56 +0000 [r9074] robert: * Updated ChangeLog and AUTHORS.txt for 2.7.4 release 2008-10-29 10:38 +0000 [r9073] robert: * Updated wrappers 2008-10-29 10:25 +0000 [r9072] robert: * From Lukas Diduch, added a multithread compsite viewer path, accessible using: osgviewerQT --MTCompositeViewer --QOSGWidget cow.osg 2008-10-29 10:12 +0000 [r9071] robert: * From James Moliere, fixed display of axis 2008-10-28 17:28 +0000 [r9070] robert: * From Lionel Lagrade, "I've replaced readsome by read+gcount." From Robert Osfeld, added throw on uncompress error. 2008-10-27 19:59 +0000 [r9069] robert: * From Chris Denham, changed nested Camera intersection test so that it requires the command line --relative-camera-scene to enable it 2008-10-27 17:42 +0000 [r9068] robert: * Added --help-env docs for OSG_MAX_PAGEDLOD 2008-10-27 17:11 +0000 [r9066-9067] robert: * Merged in comment split code from the old flt plugin so that FLT comments string with returns in them are put into separate description entries. * From Wojciech Lewandowski, "I am sending a really minor fix for StatsHandler::reset method. We dynamically add and remove slave cameras in our application. StatsHandler does not automatically adapt to this situation, and we call StatsHandler::reset to force it to update number of cameras and their graphs. Unfortunately, if stats were already drawn, reset would not remove former graph drawables and they would remain frozen below new stats. This update fixes it. " 2008-10-27 16:16 +0000 [r9065] robert: * From Chris Denham, default scene that tests the use of in scene graph Camera which has a RELATIVE_RF ReferenceFrame. 2008-10-27 16:06 +0000 [r9064] robert: * From Chris Denham, fixed support of in scene graph osg::Camera's with ReferenceFrame of RELATIVE_RF. 2008-10-27 15:26 +0000 [r9063] robert: * From Katharina Plugge, "I found a bug in the OpenFlight-Plugin. When exporting to OpenFlight it could happen that palettes of an external reference like the texture palette are set wrong, because they are overwritten by parent settings (userData), which actually do not refer to palette entries respectively ParentPools (happens for example if a Transform is parent of a ProxyNode). The static cast from userData to ParentPools should therefore be a dynamic cast. --------------------------- function FltExportVisitor::writeExternalReference( const osg::ProxyNode& proxy ): Line 423 in file expPrimaryRecords.cpp has to be changed from const ParentPools* pp = static_cast<const ParentPools*>(proxy.getUserData() ); to const ParentPools* pp = dynamic_cast<const ParentPools*>(proxy.getUserData() ); " 2008-10-27 13:09 +0000 [r9062] robert: * Various warning fixes 2008-10-27 11:49 +0000 [r9061] robert: * Updated wrappers 2008-10-27 11:08 +0000 [r9060] robert: * From Mathias Froehlich, "This change is a result of a recent thread on osg-users. The semantic change that went into the ac loader with the past patch was incorrect wrt the document describing the behaviour of ac files and inconsistent with what ac3d itself displays for that files. This attached change reverts the behaviour to the original one. The infrastructure to change this is left in place. The change is based on rev 9045." 2008-10-27 10:42 +0000 [r9058-9059] robert: * From Blasius Czink, "Among other things I added support for atomic operations on BSD-like systems and additional methods (for "and", "or", "xor"). " and a later post the same osg-submissions thread: "it's been a while since I have made the changes but I think it was due to problems with static builds of OpenThreads on windows. I was using OpenThreads in a communication/synchronisation library (without OpenSceneGraph). It seems I forgot to post a small change in the CMakeLists file of OpenThreads. If a user turns DYNAMIC_OPENTHREADS to OFF (static build) OT_LIBRARY_STATIC will be defined in the Config. Without these changes a windows user will always end up with a "__declspec(dllexport)" or "__declspec(dllimport)" which is a problem for static builds." And another post from Blasius on this topic: "I tested with VS2005 and VS2008. For 32 bit everything works as expected. For x64 and VS2008 I could successfully do the cmake-configure and then the compilation but I had occasional crashes of cmTryCompileExec.exe (during the cmake-configure phase) which seems to be a cmake bug. With VS2005 and 64bit cmake does not set _OPENTHREADS_ATOMIC_USE_WIN32_INTERLOCKED although the interlocked functionality should be there. If I place the source snippet from the CHECK_CXX_SOURCE_RUNS macro to a separate sourcefile I can compile and run the resulting executable successfully. Forcing OPENTHREADS_ATOMIC_USE_WIN32_INTERLOCKED (on VS2005/x64) reveals a bug in "intrin.h" which seems to be fixed in VS2008 but not in VS2005. In case anyone is interested the lines: __MACHINEI(unsigned char _interlockedbittestandset(long *a, long b)) __MACHINEI(unsigned char _interlockedbittestandreset(long *a, long b)) __MACHINEX64(unsigned char _interlockedbittestandset64(__int64 *a, __int64 b)) __MACHINEX64(unsigned char _interlockedbittestandreset64(__int64 *a, __int64 b)) should be changed to: __MACHINEI(unsigned char _interlockedbittestandset(long volatile *a, long b)) __MACHINEI(unsigned char _interlockedbittestandreset(long volatile *a, long b)) __MACHINEX64(unsigned char _interlockedbittestandset64(__int64 volatile *a, __int64 b)) __MACHINEX64(unsigned char _interlockedbittestandreset64(__int64 volatile *a, __int64 b)) The worst thing that can happen is that interlocked funtionality is not detected during cmake-configure and the mutex fallback is used. Which reminds me another small glitch in the Atomic header so I attached a corrected version. Why is the OT_LIBRARY_STATIC added to the config file? It is not needed anywhere. OT_LIBRARY_STATIC is needed if you are doing static-builds on Windows. See my previous post on that. " * Fixed positioning of wings 2008-10-27 09:48 +0000 [r9057] robert: * From Mathieu Marache, "I came across a bug when building OpenSceneGraph with MSVC_VERSIONED_DLL, NMake makefiles and CMake 2.6.2. The compilation fails because it tries to copy ot11-OpenThreads.lib to OpenThreads.lib which is valid for the 2.4.x era of CMake but not anymore in 2.6.x era. The provided file from the CMakeModules directory adds a tests on the CMake version and corrects this. Works for me now." 2008-10-27 09:44 +0000 [r9056] robert: * From Alberto Lucas, fixed typo 2008-10-26 22:22 +0000 [r9054-9055] robert: * Improved the support for no pre compile, and configuring the number of threads in the DatabasePager. * Improved the error reporting 2008-10-25 13:17 +0000 [r9053] robert: * From Jim Vaughan, - Matrix transform nodes were stripped out, and the vertices and normals of each node were transposed by the modelling matrix. My change preserves the matrix transform nodes, so that models can still be articulated by changing the matrices. - Lights were copied from the COIN scenegraph to the OSG scenegraph, but they were not associated with a LightSource node. My change for this creates a Group and adds a LightSource for each Light. - If VRML textures have names, the name is now copied to -- Form Robert Osfild, changed SbString to std::string usage M Inventor/ConvertFromInventor.h M Inventor/ConvertFromInventor.cpp 2008-10-24 11:38 +0000 [r9051] robert: * From Alberto Luaces, "it seems a copy-paste error is present on the OBJ loader when parsing the options given by the user. "noTesselateLargePolygons" is being activated instead of "noTriStripPolygons". I'm attaching the fixed file." 2008-10-24 10:02 +0000 [r9050] robert: * Fixed typo 2008-10-24 09:59 +0000 [r9049] robert: * Add osgParticle:: qualifiers in front of Program entries to avoid issues when combining osg::Program and osgParticle::Program in a single app 2008-10-24 09:49 +0000 [r9048] robert: * Changed timing stats to osg::INFO level 2008-10-24 08:09 +0000 [r9047] robert: * Removed debugging test. 2008-10-23 16:33 +0000 [r9046] robert: * Introduced new method of management the number of PagedLOD active, by using a capping the number of PagedLOD to a sepcified maximum, with pruning of inactive PagedLOD when the total number of inactive and active PagedLOD goes above the maximum. To enable the mode set the env var OSG_MAX_PAGEDLOD to a value something like 1000. 2008-10-21 16:39 +0000 [r9045] robert: * From Panagiotis Koutsourakis, "We are using Open Scene Graph for an application and we need COLLADA support. While testing the pluggin we found a small bug and we are submitting a patch. The first attachment is a small program that creates a scene with two pyramids, transformed by two instances of osg::PositionAttitudeTransform. One of them is rotated 90 degrees in the X axis, and the scene is exported both in the native OSG (.osg) and COLLADA (.dae) formats. In the first case the rotated pyramid is displayed correctly whereas in the second the pyramid seems not to be rotated. In the COLLADA 1.4.1 specification (found at http://www.khronos.org/collada/) it is specified that "The <rotate> element contains a list of four floating-point values [...] followed by an angle in degrees" but the plugin seems to write the value in radians. The problem seems to be in the method daeWriter::apply() that seems to be writing the angle value in radians to the COLLADA file. The patch can be found in the second attachment and is simply a call to RadiansToDegrees wrapped around the angle. " 2008-10-21 16:32 +0000 [r9043-9044] robert: * From Wojciech Lewandowski, "I made a minor tweak in StandardShadowMap.cpp. As agreed with J-S I have added AlphaFunc/AlphaTest to shadow camera stateset to make sure transparent objects will not cast blocky solid shadows." * From Chris Denham, "However, just spotted another inconsistency between UFOManipulator::getMatrix() and UFOManipulator::getInverseMatrix() It assumes that inverse(_inverseMatrix * _offset) = _offset * _matrix This is only true when _offset=identity, so I think it should be inverse(_offset) * _matrix This inconsistency can cause problems when switching from UFO to other manipulators, because the UFO:Manipulator::getMatrix function is not necessarily returning a correct inverse of the currently set ModelViewTransform. It was tempting to change the name of the _offset member to _inverseOffset, or to maintain both variables, but in the end went for the minimal change." 2008-10-21 16:27 +0000 [r9042] robert: * From Per Fahlberg, "I ran into a problem when using another library that implemented the same functions as the osg jpeg plugin, i guess they both originated from the same example code :) As a solution I added a namespace in ReaderWriterJPEG.cpp around the functions. " 2008-10-21 15:51 +0000 [r9041] robert: * #if'd out an premature StateSet optimization that was causing problems with datasets that mixed multi-texture coord geometry with single texture coord geometries in a single scene graph. 2008-10-21 09:50 +0000 [r9040] robert: * Updated wrappers 2008-10-20 16:24 +0000 [r9038] robert: * Introduce osgDB::FileCache, and updated osgfilecache and DatabasePager to use it. 2008-10-20 08:43 +0000 [r9037] robert: * Introduced support for controlling mipmapping of osgTerrain::ImageLayer and compression of osgTerrain::HeightFieldLayer. 2008-10-17 09:16 +0000 [r9036] robert: * From Paul Melis, fixed typo 2008-10-15 10:07 +0000 [r9034] robert: * From Chris Denham, "I noticed that UFOManipulator _matrix and _inverseMatrix may be inconsistently set due to typo in UFOManipulator::home(). I assume the intention is that _matrix and _inverseMatrix are kept consistent, so corrected file attached. ///////////// OSG 2.6 ////////////////// _inverseMatrix.makeLookAt( _homeEye, _homeCenter, _homeUp ); _matrix.invert( _matrix ); ///////////// after typo correction ///////////////// _inverseMatrix.makeLookAt( _homeEye, _homeCenter, _homeUp ); _matrix.invert( _inverseMatrix ); ///////////////////////////////////////" 2008-10-14 17:20 +0000 [r9033] robert: * Changed erroneous ZLIB_INCLUDE_DIRS to ZLIB_INCLUDE_DIR 2008-10-14 16:57 +0000 [r9032] robert: * From Jason Beverage, "Here is a small change to the CURL plugin to distinguish between a 400 level error and a 500 level error. If a 400 level error occurs, a FILE_NOT_FOUND ReadResult is appropriate. If a 500 level error occurs (such a 503, Service unavailable), the application might want to try to load the file again in a few seconds/minutes. This submission returns ERROR_IN_READING_FILE if a 500 level error occurs so that clients can easily distinguish between the errors. The actual error code is also added to the "message" of the ReadResult so if a client needs more information, they can just parse the message to retrieve the error code." 2008-10-14 16:44 +0000 [r9031] robert: * Converted M_PI* usage across to osg::PI 2008-10-14 16:35 +0000 [r9030] robert: * From Ricard Schmidt, dot writer plugin. 2008-10-14 15:24 +0000 [r9029] robert: * From James Moliere, " The code below is to show how a heirarchy of objects can be made within a scenegraph. In other words, how there can be a parent/child relationship between objects such that when a parent is rotated or translated, the children move is respect to it's parent movement. A robotic arm is used in this example because this is what I'm using OSG for." 2008-10-14 15:10 +0000 [r9028] robert: * Removed geomoflife_frag.cpp experiement from CMakeList.txt file 2008-10-14 14:58 +0000 [r9026] robert: * From J.P Delport, game of life example that demonstrates ping pong render to texture rendering 2008-10-14 14:37 +0000 [r9024-9025] robert: * Added zlib support to curl and ive plugins * Added debug timing code 2008-10-14 14:27 +0000 [r9022-9023] robert: * Added a Refrenced::getGlobalReferencedMutex, and OpenThreads::ScopedPointerLock() and use of this in add/removeParent() codes to avoid threading problems when using atomic ref counting. * UPdated version numbers 2008-10-10 12:01 +0000 [r9021] robert: * Moved compress/uncompress code across to using gzip compatible methods 2008-10-09 18:46 +0000 [r9020] robert: * Added initial cut of gz compress/uncompress plugin 2008-10-09 17:02 +0000 [r9019] robert: * Initial cut of zlib based compress/uncompress plugin 2008-10-09 13:16 +0000 [r9017] shuber: * From Stephan Huber: updated XCode-project, added osgVolume-lib 2008-10-09 08:52 +0000 [r9016] robert: * Fixed the frame rate reporting so that it handles the case when animation is slowed or speeded up _______________________________________________ osg-users mailing list [email protected] http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
