All Implemented Interfaces:

Cloneable

Enclosing class:

Life

public static class Life.LifeKernel
extends com.aparapi.Kernel

LifeKernel represents the data parallel algorithm describing by Conway's game of life. http://en.wikipedia.org/wiki/Conway's_Game_of_Life We examine the state of each pixel and its 8 neighbors and apply the following rules. if pixel is dead (off) and number of neighbors == 3 { pixel is turned on } else if pixel is alive (on) and number of neighbors is neither 2 or 3 pixel is turned off } We use an image buffer which is 2*width*height the size of screen and we use fromBase and toBase to track which half of the buffer is being mutated for each pass. We basically copy from getGlobalId()+fromBase to getGlobalId()+toBase; Prior to each pass the values of fromBase and toBase are swapped.
