OCR: About the Program This program was written with the MDS assembly language development system. phtures were created with MacDraw and MacPafitte pictures and the special font were added to the gram using the Resource Editor. The program simulates 3-D flightising matrix transforms ( with integer math.) 444 matrix repre- senting the spaceship's currentition and direction i computed, and the stars' positicars stored as vec- tors. The matrix is multiplied beach of the vectors to compute the stars' apparent pions relative to the ship. The stars are plotted using "gnomonic" ( or "perspective") projection. For meoinformation, consult the book Fundamentalinteractive Compute Graphics by James D. Foley andresdVan Dam. The database of stars was compild from the follow- ing sources;Byte magazine (Jul985, p. 107); The Peterson Field Guide to the Stard Planets; Gliese' Catalog of Nearby Stars; and thale Bright Star Catalog. (The last two are foundinly in large uni- versity libraries.) Acknowledgment Limitations Exit Help Return to Main Menu
