Programming Examples

Part of the Symbolic Computation book series (SYMBOLIC)


The following examples should convey a feeling for the differences between programming in GEO++ and programming in PHIGS. We begin with examples taken from “Understanding PHIGS” (Brown, 1985). They have been modified slightly in order to fit into a consistent example “Office Layout Application”, well known example for editing a graphics object hierarchy, first used in the standard text-book (Foley & van Dam, 1982). For the PHIGS examples, pseudocode is used. There follow some examples with our radio and consideration about interactive generation of primitives using PHIGS.
