METHOD AND APPARATUS FOR MULTIRESOLUTION GEOMETRY CACHING BASED ON RAY DIFFERENTIALS

摘要

A method and apparatus for rendering a plurality of objects. The method includes receiving ray differential information associated with a ray (210), determining a resolution (220) associated with a surface patch based on at least information associated with the ray and the surface patch, generating a geometry representation (240) based on at least information associated with the surface patch and the resolution, and determining whether the ray and the surface patch intersect based on at least information associated with the ray and the geometry representation. The determining a resolution includes processing information associated with the ray and the surface patch, determining a ray differential based on at least information associated with the ray and the surface patch (330), processing information associated with the ray differential and the surface patch, and determining the resolution based on at least information associated with the ray differential and the surface patch (350).
