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.

Abstract: A workstation for processing and producing a video signal comprises a video input system, a video graphics processor, and a video output system. The video input system may comprise a video input module, a first video pipeline, and a second video pipeline. The video output system may comprise a receiver, a video pipeline and a video output module. In addition, the video input system may comprise a video input module having a specific configuration and a video processing module having a connector for coupling the video input module, the specific configuration of the video input module setting the characteristics of the video processing module. The video output system may comprise a video processing module having a connector for coupling a video output module and a video output module having a specific configuration, the specific configuration of the video output module setting the characteristics of the video processing module.
