! Writing a input file is principally a matter of defining a special aggregate object, the World object, ! which is a list of the objects in the scene. When writing a input file, all objects that are instantiated outside of object-definition blocks are added to the World object; you need not (nor should you) define the World object explicitly in the input file. *************** *** 67,73 **** group of one or more metaballs. Each metaball is defined by its position p, radius r, and strength st. ! For now, see the source code for more explicit documentation. There is no inverse mapping method for blobs.
