We are interested in any work that has been done in Smalltalk on the following: 1. Hidden line removal for three-dimensional graphics representations 2. Fill for non-rectangular areas that are reasonably efficient. (Yes, we do know about the "smear" technique as per the Tektronix Form class examples.) Any ideas on the above will be appreciated. --dick peskin <peskin@caip.rutgers.edu>

Have you seen the area fill in The Analyst (by Xerox Special Information Systems) ? It performs acceptably fast and is fun to look at on the screen :-) I don't know whether the method is available separately, but I suspect that it is based on some published algorithm and that a decent Smalltalk hacker should be able to reproduce it in a day or so. I'll look it up... >--dick peskin <peskin@caip.rutgers.edu> Hans-Martin Mosner <hmm@unido.uucp> -- Hans-Martin Mosner | Don't tell Borland about Smalltalk - | hmm@unido.{uucp,bitnet} | they might invent Turbo Smalltalk ! | ------------------------------------------------------------------------ Disclaimer: Turbo Smalltalk may already be a trademark of Borland...
