Though you cannot see them from Workbench, this drawer is
chock-full of delightful fractal formulas. They are arranged categorically
for easy reference.
Formulas are stored as plain ascii files, so you may examine
and modify them with any text editor. A commented example follows:
----------------------------------------------------------------------------
; Point x y
Point 156 169 ; Defines the points in the fractal seed
Point 117 74 ; These are pixel coordinates, where 0,0
Point 158 161 ; is the upper left corner
Point 177 70
Point 150 10
; Angle Degrees Length
; Angle 35.5 50 ; This is an alternate way to enter points for
; fractal seeds.
; Give the degrees deviation from the current
; course, and how far to go.
; Detail short_enough
Detail 3.245846 ; A line segment shorter than this will be
; drawn as a line, rather than replaced with
; a copy of the seed. Smaller numbers give
; more detail, and take longer.
; Depth max_depth
Depth 12 ; This is the maximum number of generations
; to go through.
; SegmentDirection string
SegmentDirection f ; defines forward/reverse for each line segment
; SegmentFlip string
SegmentFlip n ; defines normal/flip for each line segment
; SegmentVisible string
SegmentVisible vivv ; defines visible/invisible for each line segment
; LevelDirection string
LevelDirection f ; defines forward/reverse for each generation
; LevelFlip string
LevelFlip nf ; defines normal/flip for each line segment
; LevelColor string
LevelColor 1 ; defines how far color advances at each generation
; Author string
; who created this work of art
Author Doug Houck, 3/Apr/88
; Notes# string
; artist's comments about his/her work
Notes1 Fire -- This might look cool
Notes2 in an animation, varying the
Notes3 seed slightly
; Color ColorRegister Red Green Blue
Color 0 0 0 0 ; The ColorRegister is one of 16 available
Color 1 0 6 0 ; in high resolution. Color 0 is always used
Color 2 0 7 0 ; for the background.
Color 3 0 8 0 ; Red, Green, and Blue may be any value
Color 4 0 9 0 ; from 0 to 15.
Color 5 0 9 0
Color 6 0 0 12
Color 7 15 15 2
Color 8 14 6 0
Color 9 8 4 7
Color 10 14 3 2
Color 11 4 4 0
Color 12 10 5 0
