Non-conforming Surface Rrepresentations

Abstract

Surface geometry is commonly represented by a collection of primitives. Conforming representations consist of primitives meeting at their boundaries (e.g., in a triangle mesh two triangles are incident upon an edge). Without the restriction to conforming elements there are no dependencies among primitives, leading to more degrees of freedom for each primitive. This yields more efficient and flexible algorithms for reconstruction, processing, and rendering, as well as compact and accurate representations.
