    Adaptive trimming of cubic triangular Bézier patches
    (The Eurographics Association, 2006) García, Ángel Luis; Miras, Juan Ruiz de; Feito, Francisco R.; Pere Brunet and Nuno Correia and Gladimir Baranoski
    We present a method to handle cubic trimmed triangular Bézier patches. This scheme makes use of levels of detail and surface subdivision to achieve a fast and flexible hierarchical data structure that is specially useful to compute surface intersections in a robust and efficient way. The accuracy of the results can be adjusted by adding or subtracting elements to the levels of detail hierarchy, and it is also easy to obtain a decomposition of a trimmed patch into single triangular Bézier patches.
