In addition to the molecular file formats, VMD can read the input file for Raster3D. (Raster3D converts an input file into a shaded raster image for use in making high quality pictures. It is often used with MolScript.) The ability to read Raster3D allows users to view MolScript files in 3D and incorporate special images into the display without having to edit the VMD code. If anyone has used this second option, we would be interested in knowing what was done.
The file format, which is part of the Raster3D documentation, describes a simple collection of triangles, spheres, and cylinders with either flat or spherical ends. Each shape is colored by an RGB triplet.
