Latest Patents

One of his latest inventions is the Multi-resolution depth buffer. This invention provides a system and method for eliminating hidden surfaces in 3D graphics, improving rendering performance by decreasing the size of the data stored in or retrieved from the depth buffer. The invention defines a threshold distance from the camera, ensuring that for certain pixels, the precision of a linear or quasi-linear depth buffer with reduced data size is equal to or greater than that of a non-linear depth buffer with its original data size. This advancement enhances the utility of linear and quasi-linear depth buffers for 3D applications optimized for non-linear depth buffers. Additionally, it includes a method for selecting the size of data to be read from the depth buffer before new depth values are computed for the same pixels.

Another significant patent is the Floating-point complementary depth buffer. This method evaluates the depth of a pixel in a scene enclosed within a view volume, rendered from a specific camera position. It involves calculating a depth value for a pixel, generated by a depth function based on the view distance within the view volume. The depth value is stored in a floating-point format, which includes a mantissa and exponent. As the distance of the pixel to the far plane decreases, the absolute magnitude of the depth value approaches the minimum non-negative number representable by the floating-point format.
