Latest Patents

St Clair's latest patents include a "Sphere mode texture coordinate generator" and a "Method and apparatus to handle immediate mode data streams in a data processing system." The sphere mode texture coordinate generator circuit is designed for use in a graphics adapter of a data processing system. It incorporates a set of input multiplexers that receive x, y, and z components of a normal vector and a unit vector corresponding to the current vertex. The circuit also features functional units such as a floating point multiplier, adder, compare-to-zero unit, and an inverse square unit, all configured to perform floating point operations on the outputs from the multiplexers. The controller manages the multiplexer select inputs to determine sphere mode texture coordinates based on the received vectors.

The second patent, a method and apparatus for handling immediate mode data streams, involves a geometry engine with multiple stages for processing graphics data. It receives an immediate mode data stream at the first stage, storing data to build a vertex data structure for further processing. This structure is then transmitted for processing in response to a signal, while default data remains in storage for subsequent structures.
