- Hurricane Julia
- By Walter Strickler
-
- Permission is hereby granted for unrestricted non-commercial use of
- this animation.
-
- To run the animation, type 'movie hurricanejulia' at any CLI prompt,
- or double click its icon. Make sure that the program 'Movie' is in
- the CLI's path, or is listed as the icon's default tool.
-
- This animation is composed of 52 Julia sets. For more information
- on the Julia set, see 'Computer Recreations' in the November, 1987
- issue of 'Scientific American'.
-
- The vital statistics for this animation are as follows:
- -Number of frames: 52
- -Refresh Rate: 15 Frames per Second
- -Number of Colors: 16
- -Graphics Mode: Non-interlaced Lo-res
- -Animation Software Used: Eric Graham's Dilbm & Pilbm
- -Animation Program Required: Eric Graham's 'Movie'
- -Memory Required: 1 Megabyte
-
- Julia set parameters are as follows:
- -Range of Real Axis: [-1.77765,1.77765]
- -Range of Imaginary Axis: [-1.25,1.25]
- -Maximum Iteration Value: 100
- -Julia Set Points: See the File 'HJ_Path'
-
- The program used to generate the individual frames is being written
- by myself in C and assembler. The inner loop is written in assembler
- and directly accesses the registers of the 68881 in a Microbotics
- multifunction board on an Amiga 1000. The IFF pictures took an
- average of two minutes each to produce.
-
- I would like to thank the following people:
-
- M. Gaston Julia: For the Julia set itself.
-
- A. K. Dewdney: For a great column ('Computer Recreations')
- and for the idea of a Julia set animation.
-
- R.J. Mical: For the color requester in the APS, and for
- Intuition which is a masterpiece of the programmer's art.
-
- The entire Amiga design Team: I am in awe of you for your
- foresight in producing such a great machine. Without you
- this would not have been possible.
-
- Rob Eisenhuth (a friend of mine): For forcing me to do
- this, general assistance, and the choice of colors.
-
- Shannon Rose (another friend): For the name of this
- animation (Hurricane Julia).
