Title: Innovations by Qun Feng (Fred) Liao
Introduction
Qun Feng (Fred) Liao is a notable inventor based in San Jose, CA. He has made significant contributions to the field of computer graphics and texturing. With a total of 2 patents, Liao's work focuses on enhancing the efficiency and quality of texture mapping in digital images.
Latest Patents
Liao's latest patents include a "Single level MIP filtering algorithm for anisotropic texturing." This method involves determining a region of support for a set of target pixels and mapping it to an elliptical area in the texture map. The process includes calculating the number of samples for each axis of the ellipse and applying a filter function to derive the final color value. The filter function utilizes a weighted sum of the color values of texels, with weights based on the Level of Detail (LOD) and the U or V coordinates.
Another significant patent is the "Approximation of level of detail calculation in cubic mapping without attribute delta function." This method addresses the continuity of texture mip-maps when neighboring pixels are mapped to adjacent cube faces. Liao's approach involves adjusting the u and v texture map coordinates to ensure continuity in the LOD across adjacent faces. This adjustment may include switching or negating coordinates, and normalization can be compensated by adding or subtracting unity from the adjusted coordinate.
