    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.

    摘要: A human-machine interface involves plural spatially-coherent visual presentation surfaces at least some of which are movable by a person. Plural windows or portholes into a virtual space, at least some of which are handheld and movable, are provided by using handheld and other display devices. Aspects of multi-dimensional spatiality of the moveable window (e.g., relative to another window) are determined and used to generate images. As one example, the moveable window can present a first person perspective “porthole” view into the virtual space, this porthole view changing based on aspects of the moveable window's spatiality in multi-dimensional space relative to a stationary window. A display can present an image of a virtual space, and an additional, moveable display can present an additional image of the same virtual space. Technology is used to determine aspects of the spatiality of the display devices in the physical world, and use the determined spatiality to affect the images displayed on the displays. For example, determined spatiality of the movable display relative to another display can be used to provide relative spatiality of images the two displays present to enhance the user's immersive perception. The movable display can context-switch between pointer functionality and spatial functionality depending on whether it is pointing toward a stationary display.
