Julia Trap
From Ultrafractal Wiki
Julia Trap is a Coloring Algorithm in sam.ucl.
Contents |
What is it?
The Julia Trap Coloring works exactly like a standard orbit trap, except that it uses a Julia set (or a M-set) as trap.
Parameters
Trap Mode
- Closest : Computes the smallest distance between the point and the Julia set and use it to determine the final color.
- Mean : Computes the mean distance between the point and the Julia set and use it to determine the final color.
Julia Set
Determines which Julia set will be used as trap. You can choose between nine "ready to use" Julia sets (1,2,...,9), the M-set and a "custom" Julia set which will use as seed what you enter in the "seed" parameter.
Trap Frequency
It enables you to make the trap "repeat" periodically (if not 0).
