  • Visibility calculations for 3d computer graphics
    Patent number: 6618047
    Abstract: Disclosed is a method of reducing the complexity of hidden surface removal in 3D graphics systems. A fuzzy projection (FF) of a surface (SU) as seen from a number of viewpoints (VP) in a bounding box (BB) is stored in a buffer (FA) having elements (FE). A combination of all the patches (PT) of the surface (SU) viewed form a fuzzy region (FR) where surfaces can be either visible, hidden, or unable to be determined with certainty as to whether or not visible/hidden. A non-fuzzy region (NF) describes those patches (PT) that are always visible.
