CHIP'S CHALLENGE
FRACTAL GENERATOR PROGRAM
INSTRUCTIONS
Chip's Challenge has a secret. In it's many codes for levels of
play, there is a code which will allow you to enter into the
infinite world of fractals. A fractal is a geometrical or physical
structure that has an irregular or fragmented shape at all scales
of measurement between a greatest and a smallest scale such that
certain mathematical or physical properties of the structure are
greater than the spatial dimensions. If you can understand the
definition, that's what a fractal is.
Fractals were discovered by a man named Benoit Mandlebrot and he
even named one of the images you'll see in this program after
himself. There are lots of different images to be seen in this
program, so don't just stay in one area. Now, on with the fun of
fractals.
The code for entering the program is MAND. After it is entered. a
picture will start to form on the screen. DON'T TOUCH ANY BUTTONS
UNTIL THE PICTURE IS DONE. When it's done, then you can move
around and zoom in to see more details. NOTE: Since each picture
has extremely fine detail, it will usually take a few minutes for
an image to form. Especially if there is black in ore around the
picture.
CONTROLS FOR THE PROGRAM:
(B) Button: When this button is pushed, it will create a box
outline on the screen which you can move around. When
the button is pushed again, the image on the screen
will zoom away from you.
(A) Button: When this button is pressed, it will also create a box
outline. When pressed again, this will cause the image
to zoom towards you.
NOTE: After the image has either been zoomed away or towards you,
take the outline off the screen and let the Lynx adjust the
picture to more detail.
OPTION 1 Button: This will create and vanish he box outline.
NOTE: Always take the outline off the screen
after you are done with it.
OPTION 2 Button: This will create the box outline and starts the
color cycling on the screen. One push on the
button causes the cycling to go forward. Another
push causes it to go backwards and a third will
stop the cycling altogether. NOTE: To change the
color of the cycling, go to the index.
PAUSE Button: This button will cause the MANDLEBROT / JULIA SET
EXPLORER INDEX to appear on the screen. In the
index, you can change the depth, color and cycle
rate of the fractal's and also create your own
pictures. The index should look like this:
MANDLEBROT EXPLORER
X: FE.0000000000
Y: FE.0000000000
STEP: 00.0800000000
DEPTH: 0100
PALETTE: 00
CYCLE RATE: 04
XJUL: 00.0000000000
YJUL: 00.0000000000
You can change anything you want on the index and it will not hurt
the Chip's Challenge game. But, before you change any of the X, Y,
XJUL and YJUL settings, look at all the different images that can
be found in the pictures on the screen. You can change the palette
and cycle rate without messing up the programmed images. NOTE:
There are two different programs to play with in this game. To
see the other images other than Mandlebrot's, go to the index and
push OPTION 2. It will change the title from MANDLEBROT EXPLORER
to JULIA SET EXPLORER.
PAUSE + Option 1: This resets to the original viewing coordinates of
the set.
PAUSE + Option 2: This copies the X,Y coordinate to the Julia set index,
enables Julia set mode and switches to the original
viewing coordinates.
That's all there is to this program. Hope this help's you have
lots of fun exploring the infinite images of the fractal
generator.

The Lynx Mandelbrot code does 48-bit fixed-point math using 8 bits of
integer and 40 bits of fraction, via the hardware multiplier (16x16) and a
lot of help from the 65C02. The comment line on it (the source) says it
was written by Steve Landrum of Blue Lightning fame. |
