Initializing
Original Image: |
Best Approximation So Far: |
This is an only-partly successful attempt to apply the genetic algorithm to evolve an approximation of a given image. The original image is very simple. The candidate approximations are grayscale images made up of 500 small squares. As time goes on, for example, you should see a darker region emerging in the upper right corner, corresponding to the black disk in the original image. However, big improvements don't seem to come up much after the first couple of hundred generations. (Still, you might get a decent approximation after several thousand generations.)
In any case, the main point of this exercise was to use an optional extension to the WebGL 3D graphics system that make it possible to work with a "floating-point color buffer". The page is not functional if that extension is not available, even if your browser does support WebGL.
