The Drogon Dive Planner
Copyright © 1999 - 2001 Gordon Henderson
The Drogon Dive Planner (DDPLAN) is yet another desktop decompression planner and simulator. It's designed to be relatively easy to use and portable to a number of different computer platforms. (Currently Linux, Solaris and MS-DOS, but it should compile on anything with an ANSI C compiler and a curses library)
You are probably asking yourself: "Why yet another free desktop decompression program? There are already several free programs that exist, Zplan, GAP, XS, Erik Bakers FORTRAN programs as well as Dave Wellers original Decocalc from the early 1990s... Not to mention the commercial packages; Abyss, DecoPlanner, ProPlanner and so on. Do we need another one?"
Well why not. My thoughts are that you can never have enough tools to test and evaluate various dive profiles and so on. At the end of the day, I wasn't happy with the interface to the software I had used in the past, or I had noticed bugs in it, or it ran on an operating system I wasn't prepared to use, so I started to write my own.
DDPLAN has most of the things in it that I want to use to plan my dives. If you find it useful for your dive planning then fine! If you think it could be improved then thats also fine - and if you let me know and I have the time then perhaps I can incorporate your suggestions and changes. If at the end of the day, it's not for you, then thats fine too. All it's cost you is a little bit of your time to download it and give it a go. Nothing ventured nothing gained and all that, eh?
DDPLAN is called DDPLAN because it's the Drogon Dive Planner. Drogon is an anagram of Gordon and Gordon is my name. My cat is called Greystoke and he has nothing to do with DDPLAN apart from walking over my keyboard a few times to make sure there were some kitty bugs left in the code...
