  • Patent number: 9984496
    Abstract: In an example embodiment, a technique is provided for encoding trim geometry for application in a GPU. For a UV trim polygon associated with a surface, the UV trim polygon is recursive subdivided into a predetermined number of tiles to produce a set of tiles. Each tile of set of tiles is represented by a value in an array, where the value indicates whether the area of the UV trim polygon corresponding to the tile is entirely solid, is entirely void, or for a case where the tile includes both a solid portion and a void portion, provides an index into an associated linear trim array that stores a trim expression. The set of tiles, and the portions of the linear trim array pointed therefrom, are applied in the GPU to render a trimmed representation of the surface.

  • Patent number: 6063128
    Abstract: A computer system for modeling is disclosed, where the computer system has a storage device, first and second platforms, a portable persistent model, and first and second platform-dependent computerized modeling systems (CMS). Each platform is interfaced to the storage device and provides system-dependent services. The first platform has a first type of operating system and a first type of computer hardware including a first memory, and the second platform has a second type of operating system and a second type of computer hardware including a second memory. The model resides in the storage device in a platform-independent format and includes persistent component objects. The first CMS resides in the first platform memory and the second platform-dependent CMS resides in the second platform memory.
