Hi,some time ago I worked on an analysis of binary cgm format. To get an impression of what is inside the cgm file in which order I wrote a very initial version of an osg cgm plugin and used it with osgviewer by drawing each element with incremented z coordinates (this feature is currently not in the plugin). The plugin is able to display some files for example http://www.agocg.ac.uk/train/cgm/examples/heartcgm.gz (there are still some color issues).
To compile this plugin the cgm folder of the appended archive has to be placed into the osgPlugins source subdirectory and the following line
add_subdirectory(cgm) has to be added to osgPlugins/CMakeLists.txt Regards Ralf
