Re: [osg-users] osgviewerd cow.osg ---no data loaded
Hi Randy, Thanks for your explicit response! Yes, I've solved this problem and the cow could appear. But another question now: The command line shows an error after osgviewerd cow.osg: Error: [Screen #0] ChooseMatchingPixelFormat -Unable to choose the requested pixel format Any suggestion? Thanks again! Do you have OpenGL drivers installed for whatever graphics hardware your machine has? That should not happen for the window that osgviewer tries to open - it specifies a basic pixel format that should work pretty much everywhere. Also - I notice you're using debug binaries, which won't be what causes the above problem, but for performance in the future you should also compile OSG in release, and generally use its own applications and examples in release mode, it gives a better impression of what OSG can do.

Hi, Error: [Screen #0] ChooseMatchingPixelFormat -Unable to choose the requested pixel format I've had this error pop up while trying to run OSG applications on a remote machine via Windows remote desktop - don't know if that's what you're doing, but if so, it's probably where the issue is arising.

Hi Tom, Thanks for your reply. But I didn't use it on remote machine.

Re: [osg-users] osgviewerd cow.osg ---no data loaded
Hi J-S, I find the BUILD_OSG_PLUGINS is OFF and FREETYPE_LIBRARY_DEBUG is not found either. But according to the http://www.openscenegraph.org/projects/osg/wiki/Support/PlatformSpecifics/V isualStudio, If I have installed 3rdparty libraries, the two above should be different. Does it means I have not got Freetype plugin? I do really find that there is a warning :Could not find plugin to read objects from file ...\arial.ttf...

Re: [osg-users] osgviewerd cow.osg ---no data loaded
Hello Randy, After installing, I don’t know how to set environment variable ”OSG_FILE_PATH” which should be the “sample” directory. Since I get only 4 files in installing directory——bin,include,lib,share，but with no sample file. See http://www.openscenegraph.org/projects/osg/wiki/Downloads/SampleDatasets Download the OpenSceneGraph-Data-2.8.0.zip file, unzip it wherever you want (it can be in a data directory parallel to your bin, include, lib, share directories, for example) then set OSG_FILE_PATH to that directory, for example (on Windows): set OSG_FILE_PATH=C:\OpenSceneGraph\data If you want OSG_FILE_PATH to be set at the system level (so you don't need to set it each time you start a new command prompt) go to your system properties, Environment Variables button and set it there. On Linux (bash), you'd type: export OSG_FILE_PATH=/home/username/src/OpenSceneGraph/data and you'd add that to your .bashrc for example. Hope this helps, J-S -- __ Jean-Sebastien Guayjean-sebastien.g...@cm-labs.com 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
