Hi Paolo, Unless someone did some major hacking to the VRML plugin, it has never had any animation support. Also hierarchical models (files including each other) weren't supported originally.

Re: [osg-users] [osgPlugins] VRML plugin: help in compiling
Hi Paolo, The openvrml loader is basic right now and cannot handle any VRML file. I suspect that this is what you are running into. If you look at the function convertFromVRML (ReaderWriterVRML2.cpp:~247) you will find that the loader can only handle Group, Transform, and Shape nodes, a subset of openvrml. There have been dynamic casts in there in the past that didn't test for null (failed) results which in turn would cause a crash. If you want to test whether this is the cause of your problem, you should probably start by monitoring entry to the above function and checking the openvrml node type by looking at obj-type().id() (returns a string with node type). You could also look through your vrml file and see whether it uses tags other than the ones mentioned above. -Keith On Wed, 7 Sep 2011, Paolo Piazzi wrote: rmilh wrote: I don't have VS2010.

1. use any open vrml library 0.18.x
2. set environment variable BOOST_ROOT to point to the root of the boost.
(needed for cmake to set boost entries automatically)
3. you will have to replace the outdated content of
OpenSceneGraph\src\osgPlugins\vrml\CMakeLists.txt with this:
FIND_PACKAGE(Boost 1.40.0 COMPONENTS thread)
IF(NOT Boost_FOUND)
RETURN()

)
SET(TARGET_H
ReaderWriterVRML2.h
ConvertToVRML.h
)
end var setup ###
SETUP_PLUGIN(vrml vrml)
4. rerun cmake and set vrml and/or boost related entries

Hi,
I followed the instructions for VRML plugin, but I wasn't able to compile it
with openVRML 0.14. Then I downloaded openVRML 0.18 Boost 1.46, but I wasn't
able to compile openVRML in order to use the .lib in the VRML plugin in OSG.
The error are like this:
Error 536 error LNK2019: riferimento al simbolo esterno void * __cdecl
openvrml::local::dl::sym(struct HINSTANCE__ *,class
std::basic_stringchar,struct std::char_traitschar,class std::allocatorchar
const )
(?sym@dl@local@openvrml@@YAPAXPAUHINSTANCE__@@ABV?$basic_string@DU?$char_traits@D@std@@V?$allocator@D@2@@std@@@Z)
non risolto nella funzione _openvrml_open_node_module
...\Projects\openvrml-0.18.8\src\libopenvrml\node_metatype_registry_impl.obj
openvrml
There are 14 errors like that. In the recent past, I tried to compile openVRML
also in Linux Ubuntu, but I coudn't do it.
Thank you!
Cheers,
Paolo
