  • Fractal generation, as for video graphic displays
    Patent number: 4694407
    Abstract: Fractals are generated based on their self-similarity properties. This is done by convolving a basic shape, or "generator pattern", with a "seed pattern" of dots, in each of different spatial scalings. The convolution results are then combined to define a multi-dimensional object, identifiable as a fractal. Two-dimensional sections of this object are used in generating graphic images for video display.
