JavaQuat 1.7.2

This is version 1.7.2 - 12/23/98
Instructions here. Take a look while the applet downloads.

There would be an applet here if your browser supported Java. Try downloading Netscape Navigator 4.5 which supports Java applets.

Quick Start

What you should see when JavaQuat start is a blue area on the left and a green or gray area on the right. The blue area is where you can control the picture you are going to draw. I call it the blue argument entry area. The numbers and button settings for a given fractal will be refered to as the fractal's arguments. On the right are four (4) drawing areas (2 by 2). Each drawing area has three (3) buttons at the bottom.

Each drawing area comes with a set of arguments pre-loaded. If you click on the "Show Args." button of a drawing area the values for the pre-loaded picture, or the last picture that was drawn on it, will be displayed in the blue argument area. If you then click on a draw button the picture described in the blue area will be drawn. To see all the pre-loaded fractals, go to each drawing area, click on the "Show Args." button and then on the "Draw" button.

If you see something in one of the pictures that you would like to enlarge, drag the mouse across the area you want enlarged. A square box will be drawn where you dragged the mouse to show the section of the current picture that will be enlarged if you proceed to click on any draw buton. The values in the blue arguments area will change to indicate the new center and new "View Size".

If you want to change the size of the picture change the value in the "Picture Size" box, just above right center in the blue argument entry area. Values between 9 and 301 should be possible, though the upper limit may depend on your browser. If you want an even bigger picture, click on the button that says "1 Big Canvas". "Picture Size" can then be set as high as 609 on some browsers.

NOTE: If you are using Netscape on a Mac you will have various things go blank frequently. If you just slightly adjust the size of the Netscape window the picture and arguments will be restored, at least for a while. If you are using any browser on any platform you will experience some minor problems. I am not aware of any bug that appears in more than one browser - platform combination or applet viewer - platform combination. That indicates to me that the problem is not with my Java code. But, of course, no code of even moderate size is ever bug free, so if you think I've goofed up (1) try another browser and see if the problem persists and (2) if it does, send me email at lystad@iglobal.net and tell me what's wrong.
