Dialog Box - called from: File menu
Virtual Reality Modeling Language files were intended for exchange of virtual reality data on the Internet. However, they have become a de facto standard for interchange of 3D data of all types.
ATOMS currently supports V1.0 ascii files.
VRML files can be viewed with Internet browsers for either Windows or Macintosh, using plug-ins such Cosmoplayer (www.cosmosoftware.com). Since the files are text, they can also be viewed on SGI and other UNIX systems. 3D Exploration (www.righthemisphere.com) is a stand-alone viewer for Windows which is independent of Internet browsers.
Most of the settings for 3D Drawing modes (3D Parameters dialogs, Input2 menu ) apply to VRML files, although there is little control of lighting (the viewer application or plug-in usually controls this, although most viewers offer few choices). Thermal ellipsoids may be drawn in VRML files, as selected in the 3D - General dialog or the Ellipsoid Parameters dialog, Input2 menu. Thermal ellipsoids are always solid, without the cut-out octant which is possible in direct screen or print drawing, and bonds are always cylindrical, not tapered.
If the buttons in this dialog are used to change 3D settings, these changes will also apply 3D Display mode on screen and in output.
