Class AfKernel

java.lang.Object

com.aparapi.Kernel

com.aparapi.examples.afmandelbrot.AfKernel

All Implemented Interfaces:

Cloneable

public class AfKernel
extends com.aparapi.Kernel

Aparapi Fractals the kernel executes the math with complex numbers. Coordinates refer to complex plane. result is a vector of number of iterations, It is transformed in a color in the GUI, not here
