摘要： A computer graphics system includes a lighting system that performs lighting efficiently by selecting dynamically the lighting space in which lighting calculations are to be performed to thereby minimize resources required to be expended to perform lighting. A particular preferred lighting coordinate system is then selected, based upon particular criteria, and the light source information is transformed to the selected coordinate system (if necessary) where lighting is performed. The dynamic selection can take many objective indicia into account, such as whether functions other than lighting must be performed in either of the coordinate systems, whether transformation of the lighting information is possible and the relative efficiencies of performing lighting in one coordinate system verses the other coordinate system. In another aspect, a lighting subsystem for use in a computer graphics system includes a dynamic light space selector for selecting dynamically a lighting space for performing lighting, a lighting processor for performing lighting and at least one switch operatively associated with and controlled by the dynamic light space selector to selectively enable the transformation of data from a first coordinate space to a second coordinate space prior to being input into the lighting processor. The dynamic light space selector thus controls the switch to operatively determine which coordinate system will be used to perform lighting in the lighting processor.

摘要： Graphics window systems which utilize graphics pipelines and graphics pipeline bypass buses. Hardware solutions for window relative rendering of graphics primitives, block moving of graphics primitives, transfer of large data blocks, and elimination of pipeline flushing are disclosed. The hardware implementations provided in accordance with the invention are interfaced along the pipeline bypass bus, thereby eliminating gross overhead processor time for the graphics pipeline and reducing pipeline latency. Methods and apparatus provided in accordance with the invention exhibit significant pipeline efficiency and reductions in time to render graphics primitives to the screen system.

摘要： A method according to the invention conserves host system resources by compressing an image region according to the type of graphics command used to generate or modify the region. As an image is being rendered, a list of modified image regions is maintained. For each modified image region, metadata are associated with the region to identify the type of graphics command that was used to produce the modification. Per-region choices of compression algorithms can then be made responsive to the metadata without regard to the content of the image data itself.

摘要： A method comprises providing image copy and modify commands to a receiver. Each copy command causes pixel values in an area of a display associated with the receiver to be copied to another area of the display and each modify command causes at least one pixel value in an area of the display to be modified. The method further comprises generating a future copy region if a future copy command that is providable to the receiver is encountered. The future copy region defines one or more rectangles of pixels on the display that are copyable in the future on the display associated with the receiver. The method also comprises using the future copy region to avoid sending a future copy command to the receiver that will copy pixel values that are to be modified on a display associated with a sending system.
