- update for incoming beta 40: new exterior types 7 & 8
interior and exterior specify special coloring
algorithms. You can specify one of them or both at the same time. They only work with
the fractal patterns.
EXTERIOR_TYPE is integer
value between 0 and 8 (inclusive) and INTERIOR_TYPE is integer
value between 0 and 6 (inclusive). When not specified, the default value of INTERIOR_TYPE
is 0 and for EXTERIOR_TYPE 1.
FACTOR is a float. Unless specified otherwise, the return value of the pattern is multiplied by
FACTOR before returning it. This can be used to scale the value range
of the pattern when using interior and exterior coloring (this is often needed to get the
desired effect). The default value of FACTOR is 1.
The different values of EXTERIOR_TYPE and INTERIOR_TYPE have the following meaning:
- 0 : Returns just 1
- 1 : For exterior: The number of iterations until bailout divided by ITERATIONS.
Note: This is not scaled by FACTOR (since it is internally scaled by 1/ITERATIONS instead).
For interior: The absolute value of the smallest point in the orbit of the calculated point - 2 : Real part of the last point in the orbit
- 3 : Imaginary part of the last point in the orbit
- 4 : Squared real part of the last point in the orbit
- 5 : Squared imaginary part of the last point in the orbit
- 6 : Absolute value of the last point in the orbit
- 7 : For exterior only: the number of iterations modulo FACTOR and divided by FACTOR.
Note: This is of course not scaled by FACTOR. The covered range is 0 to FACTOR-1/FACTOR. - 8 : For exterior only: the number of iterations modulo FACTOR+1 and divided by FACTOR.
Note: This is of course not scaled by FACTOR. The covered range is 0 to 1.
