Hi all,
I was playing around with the dev release 2.9.14 on Windows (not the
latest svn) and had to play around with some build files to get it to
compile. I'm no guru on cmake by any stretch, but to compile the plugin I
had to edit one of the cmake files. First though, I downloaded openvrml
0.17.12 and used my existing boost build (1.44.0 the plugin readme says
to use an older version of boost, but I think this version works too). I
noticed that cmake wanted to find openvrml _antlr and _regex libraries,
but both are no longer used in openvrml. I commented out the following
lines in src/osgPlugins/vrml/CMakeLists.txt:
# FIND_LIBRARY(OPENVRML_ANTLR_LIBRARY
# NAMES antlr.lib
# PATHS $ENV{OPENVRML_DIR}/lib)
# FIND_LIBRARY(OPENVRML_ANTLR_LIBRARY_DEBUG
# NAMES antlrd.lib
# PATHS $ENV{OPENVRML_DIR}/lib)
# FIND_LIBRARY(OPENVRML_REGEX_LIBRARY
# NAMES regex.lib
# PATHS $ENV{OPENVRML_DIR}/lib)
# FIND_LIBRARY(OPENVRML_REGEX_LIBRARY_DEBUG

and
SET(TARGET_LIBRARIES_VARS
# OPENVRML_ANTLR_LIBRARY
# OPENVRML_REGEX_LIBRARY
OPENVRML_LIBRARY
JPEG_LIBRARY
PNG_LIBRARY
ZLIB_LIBRARY)
Then I was able to run cmake without a problem.
The last thing I had to do was to set one of the use/build macros
defined in the openvrml library file openvrml-config.h. You need
to choose either OPENVRML_USE_DLL or OPENVRML_USE_LIB depending on
whether you are linking to dynamic or static libs. In VisualStudio, you
just open up the properties window, find the Preprocessor menu under
Configuration Properties-C/C++. Then click Preprocessor Definitions
and add eitherOPENVRML_USE_DLL or OPENVRML_USE_LIB.
I didn't notice any mention of this in the osg-users list, so I thought
I'd send this out in case anyone else had this problem. If there is a
cleaner solution that I missed, please do correct me.

Re: [osg-users] VRML plugin working in iPhone / iOS?
Hi Ryan, I can't comment on the issues of getting external dependencies to compile under iOS, this I'd have to defer to those who have worked under iOS and with these 3rd party libraries. What I would add is that my expectation for mobile and embedded application develop is that the constraints of the system would be tight enough that you'd want to minimize the number of dependencies your application has to keep the runtime memory footprint as well as use of space and bandwidth on the device. Secondy you would typically want to optimize the databases to work within the constraints of the device, either the GL target or simply the number textures, fillrate and vertices per second that the database can handle. Combine all these constraints together and you would naturally lean towards using native binary formats like .osgb and offline pre-processing all databases for the target. The pre-processing of database would be done on a workstation with all the 3rd party dependencies you'd need to enable import of the data you need. Once could potentially do this procesing in the cloud at runtime too. Robert.

Re: [osg-users] VRML plugin working in iPhone / iOS?
Hi Ryan Forgot the Vrml plugin :) I don't think OpenVrmls dependencies are a problem, but OpenVrml itself probably will be as it uses OpenGL. I think Roberts advise is very true here (as usual), even if you get OpenVrml compiling it's going to add a lot of bloat to your app due to all the extra dependencies. The conversions seem like hassle, but once you have a work flow going it only takes an extra click or two.

DAE OBJ FBX 3DS Some of those formats are fine others i'm not sure about. DAE, if you can find the dependencies built for IOS then no probs as I think you build OpenCollada yourself OBJ, this plugin has no dependancies so should be fine (I think i've used it in fact and just built fine on my machine) FBX, i'm pretty sure this is a no show as you have to use prebuilt libs, which at the moment don't include IOS 3DS, again no dependancies so should be fine (just built fine on my machine) For features like skinning etc which you might be using DAE or FBX for, I have been converting them to osgb to avoid having to build the plugins on every platform.

Any thoughts on VRML and OpenVRML dependencies? -- Read this topic online here: http://forum.openscenegraph.org/viewtopic.php?p=38018#38018 I am quite sure OpenVRML will not work on iOS out of the box. There are lots of dependencies that would have to be ported for it to work and I am sure nobody did that. Furthermore, the renderer included in OpenVRML is pretty much standard OpenGL 2.x, it certainly does not support OpenGL ES needed on iOS and thus the code will fail to compile. However, feel free to contact authors and ask them directly. On the other hand, I would stay away from VRML as a plague - it is a long obsolete format, the plugin doesn't support every VRML feature and parsing it is very expensive. You will be far better off using one of the binary formats, especially when you are on an embedded device with limited memory and CPU power. Most likely you need to only export some meshes and materials, VRML is a a huge overkill for that. If your data are in VRML, convert them on the desktop and use only the converted files on the device.

[osg-users] VRML plugin

I am trying to save some vrml file, however I get an error message similar to
the following
Warning: dynamic library '/usr/local/lib64/osgPlugins-2.8.3/osgdb_vrml.so'
exists, but an error occurred while trying to open it:
libopenvrml.so.4: Could not open: File or directory not found
Error writing file /tmp/saved.wrl: Warning: Could not find plugin to write
nodes to file /tmp/saved.wrl.
If I set the the ld_library_path correctly it reduces to
Error writing file /tmp/saved.wrl: Warning: Could not find plugin to write
nodes to file /tmp/saved.wrl.
... and that's where I am stuck.
I use OpenSceneGraph-2.8.3 with openvrml-0.14.3
Any suggestions?
Cheers,
Alex

[osg-users] VRML plugin
Hi all, Given that the VRML plugin is a bit of work to compile due to the dependence on a very old version of OpenVRML, I've built a binary packages of OpenVRML-0.14.3 for Win32 Visual Studio .NET 2003 and Visual Studio 2005, and Mac OS X 10.4 32-bit universal. The binaries are here for your pleasure: http://www.artoolworks.com/dist/openvrml/0.14.3/ I also note that previous discussion about why the VRML plugin couldn't be updated to a newer version of OpenVRML centred on the boost dependency. I'm sure that thats much less of an issue now that we have boost binaries for most Linux distros, plus Windows and Mac. http://www.boostpro.com/download http://pdb.finkproject.org/pdb/browse.php?summary=boost Of course, the bigger issue with the VRML plugin is that it doesn't support any sort of animation. OpenVRML 0.14.3 supports animation including animated textures. Does anyone here have a good knowledge of the VRML, good enough to add support for importing VRML animations from OpenVRML nodes?

Does anyone here have a good knowledge of the VRML, good enough to add support for importing VRML animations from OpenVRML nodes? That plugin has much larger issues than lack of animation support :) It was never intended as a comprehensive VRML loader/viewer, the original purpose was a loader of legacy 3D models created in 3DS Max - basically only textured meshes were supported, nothing else. It is quite a bit further than that now thanks to the work of many people on this list, but it is still very far from loading any VRML you can throw at it. If you need a lot more than that, you should likely use OpenVRML directly or some other tools (COLLADA?). However, code contributions are certainly welcome.

No, if you have the VRML plugin, you do not need the Inventor, unless you want to load also the Inventor (.iv) files. I suspect that if your plugin is compiled correctly but doesn't load, most likely either the OpenVRML library or some of its dependencies cannot be loaded at runtime (make sure it is either in one of the standard lib directories or in the LD_LIBRARY_PATH) Set export OSG_NOTIFY_LEVEL=DEBUG and try to run the viewer. Then look for any unresolved symbols while it is trying to load the VRML file. Most likely the dynamic linker cannot find something.

Re: [osg-users] vrml plugin problems
Hi Ben, I am trying to load a VRML file, but I get the error message: Warning: Could not find plugin to read objects from file “foo.wrl”. [...] I compiled OSG 2.6.0 from src on Debian Etch. I am using OpenVRML version 0.14.3. Do I need a newer version of OpenVRML? (I set the path to the OpenVRML includes as well as libopenvrml.so during the CMake configuration). Did you verify that the osgdb_wrl.so plugin was compiled and can be found? You can enable verbose debugging messages by setting OSG_NOTIFY_LEVEL=DEBUG before running osgviewer, and that might show if something is wrong there. It will print out where it looks for the plugin, whether it finds it, and whether it loads it correctly or not. If the plugin is there, is loaded (as printed in the debug messages) but it still says that it can't find a plugin, it might mean that the plugin depends on some other dynamic library which isn't being found at runtime. This might depend on where OpenVRML is installed and whether your LD_LIBRARY_PATH includes the right directory to find its dynamic libraries (if any) - note I'm on Windows most of the time so I can't really help more than that. I had VRML files working with OSG 2.4 a long time ago. Back then I also set up the Inventor library during the install. But I forgot what that library does, why it’s needed, and even where to get it. Do I need it here too? The Inventor plugin can also read VRML files, so if OSG was using that one to read your VRML files before, it might mean that the OpenVRML plugin never worked for you but you never knew it... :-) Hope this helps, J-S -- __ Jean-Sebastien Guay[EMAIL PROTECTED] http://www.cm-labs.com/ http://whitestar02.webhop.org/ ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org

Thank you for the tip. That environment variable flag helped me see that OSG found the osgdb_vrml.so plugin, but then failed when loading the openvrml.so library.

Re: [osg-users] VRML plugin
Hi Will, I suspect that you are trying to load VRML 1.0 files. OpenVRML only supports VRML97 (VRML 2.0) files. Perhaps, you could convert your WRLs to VRML97 (or OBJ, COLLADA, etc) using a conversion tool (3ds Max, Blender?).
