Can anyone tell me the status of Decartes? It's a neat 2-D graphics
program that hass al sorts of graphing optins, I saw version 1.0 of
it somewhere. Is it commercial? Freeware? Shareware? Anyone know?
Also, what is the best current pd/feeware/sharware Mandelbrot generator,
and where can I get it?
Thanks!

To my knowledge, that is the most recent version. It is a commercial product, marketed by Mindware. I paid about $35 for it. Descartes does a decent job at plotting equations, letting you plot multiple lines, and in multiple colors, use trig and hyperbolic functions; it will do derivatives (in closed form, not numeric solutions). With the 1.3 printer drivers, you can even get some decent printed output. It's still bitmap output, though, so you have to experiment, and your choices will be limited. Don't expect to use it for plotting data, as it can't generate plots using input data. It also has no provisions for adding legends, labels, or titles. Just numbers and tic marks on the axes. This is its major shortcomming, in my opinion. It also does some Very Bad Things with regard to proper Amiga programming. It busy-waits, even when waiting for requester input, slowing down the system needlessly. I run it at priority -1 to get around that. It also has some hard-coded paths, which I patched using NewZap so I could use it more conveniently on my hard disk. I'd call it an okay first try. I'd love to see it fixed and upgraded, but I haven't heard anything to that effect. -- Eric Kennedy ejkst@cisunx.UUCP

I release this program (source and all) to Fred over a year an a half ago. It is very fast using a special fixed point math generator. It also has a powerful picture coloration mechanism. The new version is MUCH MUCH nicer and will be released to comp.sources.amiga within a month. email me if you want to be a beta tester. >* Rich Carreiro "Back off man, I'm a scientist." * >* rlcarr@athena.mit.edu - Dr. Peter Venkman * Kevin -- UUCP: kevin@uts.amdahl.com or: {sun,decwrl,hplabs,pyramid,seismo,oliveb}!amdahl!kevin DDD: 408-737-5481 USPS: Amdahl Corp.
