    摘要: The present invention provides a system for a video window in a graphics background of a screen. The video window is allowed to be removed anywhere and be scaled up or down. The system comprises a receiving module to receive the video and graphics data and group both of the data in segment, a scaling module to process the scaling by applying the provided recursive pixel-extracting algorithm for the video segment, and an overlapping module to post the scaled video data on the graphics data in accordance with a boundary condition.

    摘要: An interface for a graphics system includes simple yet powerful constructs that are easy for an application programmer to use and learn. Features include a unique vertex representation allowing the graphics pipeline to retain vertex state information and to mix indexed and direct vertex values and attributes; a projection matrix value set command; a display list call object command; and an embedded frame buffer clear/set command.

    摘要: A graphics system including a custom graphics and audio processor produces exciting 2D and 3D graphics and surround sound. The system includes a graphics and audio processor including a 3D graphics pipeline and an audio digital signal processor. The same texture mapping hardware used for color texturing provides resampled z texturing for sprites with depth or other applications. A z blender performs a z blending operation in screen space to blend surface z values with z texel values to provide per-pixel mapping of resampled z textures onto sampled 3D surface locations. Z texels can represent absolute depths or depth displacements relative to primitive surface depth. The z texel values may add to or replace primitive surface z values, and a constant bias may be added if desired. The resulting depth values are used for occlusion testing. Z textures can be generated by copying out portions of an embedded z buffer and providing the copied depth values to the texture mapping hardware. Multiple z texel formats are supported.
