I have two machine that are trying to open the same set of generated OSG files.
When I open the sample cow.osg on the OpenGL4 machine, the cow looks metallic and shiny. When it is opened on the OpenGL3 machine, the cow is white and matted. Then when I try to open the osg that I generated on the OpenGL4 using these instructions http://www.openscenegraph.org/documentation/osgdem.html (instead of ive, I use the osg extension). When I try to open the generated osg file on the opengl3 machine, the osgviewer crashes with the some error message in the console. Error: glGenBuffers not supported by OpenGL driver Error: glBindBuffer not supported by OpenGL driver Error: glBufferData not supported by OpenGL driver I noticed that the command line arguments on osgdem.exe specifies that OpenGL compression to be used. But when I generated the osg files, I did not explicitly use the opengl compression parameters. Is that a safe way to generate these OSG files to use a lower version OpenGL driver? I am developing a product where I cannot always force the users to upgrade their hardware. ( assuming the OpenGL3 based machines are around for 5 or less years) _______________________________________________ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
