Name. pfg2D 2. Author. Przemyslaw Prusinkiewicz, University of Calgary Calgary, Alberta Canada pwp@cpsc.ucalgary.ca 3. Availability. Available by anonymous ftp from hercules.cs.uregina.ca in pub/pfg in tar and hqx format 4. Language. Written in C. Aztec C68K compiler Version 3.4b. 5. Platform. Macintosh 6. Operating system. Macintosh 7. Code. Includes source code. 8. User interface. The user edits L-system data files which are read by the program. 9. Capability. Pfg2D produces black and white images of two-dimensional structures specified by L-systems with turtle interpretation. The program supports bracketed L-systems with no context, one-sided context and two-sided context. 10. References.

Includes sample data files ----------------------------------------------------------------------------- ----------------------------------------------------------------------------- IBM-PC: IBM-PC 1 by Arnd Burghardt ----------------------------------------------------------------------------- > 1. Name. Name of the program. l-sys.exe in archive l-system.zip > 2. Author. Name, address, and e-mail address. Me, myself and I, so: Arnd Burghardt An der Tillyschanze 4 W-3392 Clausthal-Zellerfeld Germany inabu@DCZTU2.bitnet inabu@ibm.rz.tu-clausthal.de > 3. Availability. Available by ftp? where? site and path. Yes, it should be on: sun.rz.tu-clausthal.de (139.174.1.3) anonymous ftp in path pub/msdos/sources as l-system.zip > 4. Language. Is it written in BASIC, Pascal, C, etc? which version? It is written in TurboPascal Ver. 5.5 (no oop). (But it'a german program with menue, variable-names and function/procedure names in G E R M A N (if you can understand it - ok)) > 5. Platform. What machines does it run on? Mac, PC, DECstation, etc. It's made for the PC (8086 and up), of course it is pascal, but TurboPascal is a special 'slang', so it will be hard to convert it to other maschines (especially the graphics will be different). > 6. Operating system. MacOS, MS-DOS, UNIX, etc. I tested many MS-DOS, IBM-DOS, DR-DOS versions, if the operating-system is MS-DOS compatibel, it works fine... > 7. Code. Is a compiled version available? Is the source code available? The zip-archive contains then compiled version l-sys.exe as well as the complete source-code. > 8. User interface. How does user the interact with the program? Are there > prompts, or dialogs and menus, or does one have to alter the code? The l-system-language is really fractint-like, but I tried to produce something easier to handle. The l-systems are - like fractint - in a special file, that can be edited with an editor, the l-system- interpreter has an own interactive editor built in. If the user knows only a little bit german, it will take no problems to user it. > 9. Capability. What kinds of L-systems can the program do? e.g., bracketed, > context-sensitive, stochastic, parametric, 3-D. Again, nearly fractint compatible so only context-free. The using of variables may simulate a (small) context. >10. Applications. How has the program been used? References? The programm stands for itself, no configuration, no other file, exept the l-system-data-file is needed, everything is detected by itself. A little utility vgatonec.exe is given as gift, for those people having a VGA monitor an a NEC DotPrinter to save the nice Pictures on paper. The frame describtion is given as softprak.ps but it is written in (again) german and the pictures an listing are not included. >11. Comments. Anything not covered above. The Programming intension was a part of my studies in informatics so I did it not for fun. It is no dirty, heavy, fast code, but in opposite a trial to make a very beauty, good readibal and non tricky program, because there will come up to three to four other guys to pump the program up. ----------------------------------------------------------------------------- IBM-PC 2 by Deren Hansen ----------------------------------------------------------------------------- Name: 0level.c, 0level2.c, 0level3.c Author: Originally published as an article with accompanying source by Hardin Brothers in PC Resource magazine, in one of the fall 1989 issues (I believe) Modified and customized by Deren Hansen, address: NMSU-EPPWS, Box 30001 Dept. 3BE Las Cruces, New Mexico USA 88001 email: dhansen@nmsu.edu Availability: Not yet available for ftp.
