Latest Patents

Christensen's latest patents include groundbreaking methods for rendering a plurality of objects. One of his patents, titled "Flexible and modified multiresolution geometry caching based on ray differentials," describes a method that involves receiving ray differential information associated with a ray. This method determines a first resolution associated with a first surface patch based on information related to the ray and the surface patch. It processes this information alongside a database to ascertain whether a geometry representation associated with the surface patch tessellated at the first resolution is present. The database is linked to multiple predetermined resolutions, with the first resolution being one of these. Notably, this method includes varying tessellation rates for different dimensions.

Another patent, "Multiresolution geometry caching based on ray differentials with modifications," further refines the rendering process. It involves receiving ray differential information, determining a first ray differential, and processing this information to select a second resolution from predetermined options. This method also includes generating additional geometry representations based on the selected resolutions, enhancing the efficiency and quality of rendering.
