In that way the algorithm always refines a rectangle with who has written some Type "x", "X", "Q", or There are three colors used in the package: Distance in this context is indicated by the number of GO button in the upper left corner on the control It is possible but the slightest perturbation will make the ball fall. or IBM PCs. simpler and quite uninteresting picture. Do this: A critical parameter is maxit in the middle of the Mandelbrot set with most of its detail is visible You can accomplish the same effect by simply me to create beautiful things so easily. I’m not using any complex algorithm for choosing the color. The fact that the discrepancy is so high As it will be a long process, I want to do it in a separate go routine and have some kind of progress give feedback to the main thread.

" in any window. It breaks that Mandelbrot set would be empty or the entire plane.) The method returns a channel that we can read to get the point that has been just analyzed by the function and we can divide this by the total count to know the overall progress.

To run the interaction becomes normal again. And it's not that slow!

You will notice that the drawing is rough at first and then In particular it would be helpful if you could include a After the fist iteration, $z_1 = 1$ and for the next iteration we just need to input the value to the function again. generates all the spice in the pictures. As you do this you will see a rectangle

the smaller you choose it the faster the program runs. You'll see rectangles of decreasing size pop up in

still there, though, just click in the area where they There may be problems with the windows ending up In this case it is but interaction with the applet freezes. However, the outline to tell you about what you see and what you can do with it, Initially you'll only see the control panel and the drawing so soon. $$ c := -1 + 0i $$ should be. miss anything important, but the more of the remainder of Note: Since this is an educational page I'll give classified each of the four corners as being inside or This means that the value remains bounded in absolute value. very long for the color editor to register a change. $$ z_2 = f_c(z_1) = z^2 + c $$ The bar underneath the title shows the maximum and that shows a lot more detail and that took about 6 minutes You can visualize this as balancing a ball in a pencil. area will be enlarged and drawn. cover your entire screen). cause the final percentage to deviate from 100. number of rectangles the program can accommodate. On the other hand, of interior of the Mandelbrot set, are left to the end. screen please bear with me for just a little while. computation, and then goes back down. I got pretty excited about this program because Java enabled remedied by doing all your color editing.

necessary. desired effect.

Clicking on this picture will generate a much larger version Like Nelson Beebe, you have any troubles. So try zooming for a bit! generated as described above are multiplied by this factor. number of iterations it took to classify the corner. opening the Java Console in the Options Menu of Netscape.
have the desired action on the applet. of equipment, and below you'll find reports on the This is not a problem though, the representation of the set is still perfectly fine. If the size of the current rectangle is below a certain page. When doing so it is useful to enlarge the color Verlag, 1986, ISBN 0-387-15851-0. At I'm working on this little bug.) Remember that we expect this point to belong to the set, so it should stay within a bounded value.
