  • Efficient anti-aliased dot rasterization
    Patent number: 6731300
    Abstract: A graphics system may be configured to render anti-aliased dots in terms of samples and to generate pixels by filtering the samples. The pixels are supplied to one or more display devices. The means used to generate the samples may perform the computation of radial distance at positions on a grid in a rendering coordinate space, and interpolate estimates for the radial distances of samples around the dot as needed based on the radii at the grid positions.
    Type: Grant

    Date of Patent: May 4, 2004
    Assignee: Sun Microsystems, Inc.
    Inventors: Nandini Ramani, Michael A. Wasserman, Michael G. Lavelle, Mark E. Pascual, Kevin Tang, Daniel M. Chao
