Which VRML 2.0 (now officially VRML97) nodes does Open Inventor support?
With almost every new release of Open Inventor, VSG upgrades its VRML support. Go to the Table of Contents of the Open Inventor on-line Reference Manual. Select Modules/Inventor/VRML/VRML2.0 nodes to go to the VRML 2.0 page which lists all of the VRML nodes. Some nodes are marked with “Action not implemented” or “Action partially implemented.” If a node is marked “Action not implemented”, Open Inventor can read and write VRML files containing that node. However, when it reads that node, it will not perform any action. If a node is marked “Action partially implemented”, see the help file to find out which features are implemented. Unmarked nodes are fully implemented.
