I am releasing ZPlot3.1 for Windows as shareware. This means you can use it on a trial basis, but register your copy with me if you would like support for the program. I also need an incentive to write future shareware versions of ZPlot. Please contact me if you are thinking of posting this version of ZPlot to other bbs.
The registration fee for ZPlot3.1 is $30 US. Please make this payable to

For help on ZPlot you can mail me a letter at the above address or email me at twgg@ix.netcom.com. Registered users can also phone me.
Disclaimer: I've tried to incorporate as much of my knowledge of fractals and complex functions in ZPlot3.1, but given the complexity of the program there's always the possibility of bugs. While I know of no bugs in ZPlot that actually bomb the program, there are some that have caused ugly lines to appear when ranges in the math package have been exceeded. Most of these problems I've fixed, but then I know the program better than anyone else, so I'm not likely to use it in a mode that will cause failure. The sample files included with ZPlot should give a good idea of how well ZPlot works.
One other area that may be an annoyance is the midpoint displacement routines. These don't always produce the results you would hope for. Sometimes you have to repeatly execute the New command, before a useable background appears(the random generator seems to hit a dead zone a lot. The algorithm is based on the psuedocode from The Science of Fractal Images and probably requires more memory than I'm able to supply it now.)
I haven't tested ZPlot at resolutions above 1024X756 or with more than 256 colors. The resolution is limited to 1024X756 max now, until I get a higher resolution monitor to work with. If you have a targa card with millions of colors, the color cycling might not work.
