  • Accurate transparency and local volume rendering
    Patent number: 9007393
    Abstract: Systems, apparatus, computer software code products and methods for enabling computer graphics systems to accurately render transparency comprise configuring a shader element of the computer graphics system to first extract all layers of an image representation and obtain depth information therefrom, and then rendering all layers back-to-front with shading enabled, such that information obtained from a previously processed layer is available for processing of a current layer.
    Type: Grant
    Filed: December 10, 2007
    Date of Patent: April 14, 2015
    Assignee: Mental Images GmbH
    Inventor: Martin-Karl LeFrancois
  • Computer graphics shader systems and methods
