-- 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
