- !Dive Instructions
- --------------------
-
- Introduction:
-
- On TV programs about fractals they often show amazing films of animated
- dives into and out of the Mandelbrot set. These films will most probably be
- made with a really awesome computer, and my guess is that they wouldn't
- attempt to generate the image in real time but make up the film step by step
- like an animation. However I thought it would be really excellent to have a
- program that would do a dive in real time, so you could steer about and go
- wherever you wanted. So I have been attempting to write such a program.
- !Dive is the present state of my work presented in a user friendly form,
- it is fairly experimental ( that's my excuse anyway ) and so is still a bit
- rough. I was going to write a text file explaining how the main routines in
- the program work, but when I came to do it I realised it was going be a
- fairly extensive venture, so best for any queries, comments etc, to be sent
- to me at the address at the end ( unless you have better, i.e newer, address
- to send them to ).
-
- Instructions:
-
- Full control of the program is by mouse and the various icons to the right
- of the screen.
-
- Steering - Clicking on the four arrows at the top of the icons will
- cause the view to pan in various directions. The direction
- arrows are highlighted to show the current direction of
- motion. The arrows keys can also be used to activate these
- icons.
-
- Zooming - The program can be switched between Zooming in, Zooming out
- and Scrolling across the set. Click on the second icon down
- to change the present option. The icon itself shows the current
- option. The 'Z' key may also be used.
-
- Restart - Click on the next icon ( mini-Mandelbrot image ) to restart
- the program. Zoom type and direction arrows are reset.
-
- Redraw - Click on the icon that looks like ( or is supposed to ) a
- pretty picture, and the image will be redrawn with no speedup
- algorithms ( ie the picture will be totally correctly drawn )
- Zoom type and direction arrows are not reset.
-
- Palette - The palette shaped icon switches between various palettes,the
- effect being immediatly obvious.
-
- Size - The number in the small box with arrows above and below is the
- size of the image being processed in pixel dimensions ( the
- picture is always square ). Clicking on the arrows will raise
- or lower the size, but the effect will not be noticeable until
- either Restart or Redraw are selected. The idea of this is to
- reduce the image size, to increase the speed of processing, but
- I prefer the big image anyway.
-
- Info Box - At the bottom of the screen is a box showing the current X
- minimum, Y minimum and width of the image. This is only a rough
- guide, it stops being any use quite soon into the dive.
-
- Quitting - Press ESC to Quit the program.
-
- And there you have it, have fun, and don't get too annoyed when the
- program screws up and puts lines all over the screen - I reserve that right!
