Latest Patents

Rolf A Van Widenfelt holds a patent for a "Method and apparatus for shadow generation through depth mapping." This invention focuses on creating shadowed scenes for interactive image generation. The method involves generating a shadowing coefficient for each pixel, which is utilized during scene rendering. The invention employs z-buffer and projective texture mapping facilities to achieve realistic shadow effects. The process includes rendering the scene from the light source's viewpoint, creating a two-dimensional depth map, and using this information to determine which pixels are in shadow. The shadow coefficient is then calculated to enhance pixel intensity, resulting in a more realistic visual experience.
