Split-level graphics library

A low level hardware dependent graphics library (binding library) between hardware independent graphics libraries and a graphics hardware unit. The binding library procedures provide a relatively low level interface that couples directly with the graphics hardware unit and only requires a relatively small amount of rewriting to accommodate different graphics hardware units while requiring no change of the hardware independent graphics libraries. The binding library procedures provide a quality meter adjustable between low speed processing high quality image rendering and low quality but faster speed image rendering. The binding library procedures perform batch processing by receiving an array of batch cells, each batch cell comprising a separate primitive. The batch array can be handed off to the binding library procedures at one setting and then processed sequentially. This configuration insures that no instruction cache misses occur during parameterization of the array (e.g., the parameterization routine fits within a standard code cache) and that few data cache misses occur. Also, the binding library procedures allow automatic translation between different texture mapping data formats so that either RGB-alpha format can be used or a format using an index into the color pallet can be used. By providing a low level interface, the present invention provides a system that is readily adaptable to different hardware graphics accelerators without requiring modifications to the graphics libraries.
