Latest Patents

One of Robert J. Casey's latest patents is a "System and method for accelerated occlusion culling." This invention involves an occlusion culling circuit designed for use in graphics computers. The circuit receives graphics primitives data, including x and y coordinates for each pixel, a z depth value, and color data. The graphics computer scans the primitive to determine a bounding volume. The z depth values of the bounding volume are compared to the depths of already rendered pixels to assess visibility. If no pixels are visible, the circuit clears the result register and processes the next primitive. Conversely, if one or more pixels are visible, the circuit renders the primitives within the bounding volume. This method allows totally occluded graphics primitives to bypass intensive processing, significantly increasing the speed and efficiency of the graphics computer.
