Deforming Subdivision Surfaces
We introduce a new algorithm for fitting a Catmull-Clark subdivision surface to a given shape within a prescribed tolerance, based on the method of quasi-interpolation. The fitting algorithm is fast, local and scalable since it does not require the solution of linear systems. Its convergence rate is optimal for regular meshes and our experiments show that it behaves very well for irregular mesh...
متن کاملDeforming Surface Features Lines in Intrinsic Coordinates
Significant local structure of terrain surfaces can be described by structural lines which are connected sets of points where the surface is approximately cylindrical, i.e., the ratio of the principal curvatures is large. At each point curvature is maximal in the curvature direction associated with the curvature with larger absolute value. These lines form the skeleton of the surface for constr...
متن کاملGamasutra - Features - "Subdivision Surface Theory" [04.11.00]
At Siggraph '98, Pixar unveiled a short animated film. Christened Geri’s Game, it was, to quote its Academy Award press release, the “endearing tale of an aging codger who likes to play chess in the park against himself.” Not only was it artistically stunning, but it was also a technological powerhouse. The short served as a vehicle to demonstrate Pixar’s latest addition to its production envir...
متن کاملDeforming Surface Simplification Based on Feature Preservation
In computer graphics, methods for mesh simplification are common. However, most of them focus on static meshes, only few works have been proposed for simplifying deforming surfaces. In this paper, we propose a new method for the multiresolution representation of time-varying meshes based on deformation area and feature preservation. Our method uses the famous QEM (quadric error metric) as our b...
متن کاملEfficient direct rendering of deforming surfaces via shared subdivision trees
In this paper, we present a subdivision-based approach to rasterize implicit surfaces embedded in volumetric Bézier patches undergoing a nonlinear deformation. Subdividing a given patch into simpler patches to perform the surface rasterization task is numerically robust, and allows guaranteeing visual accuracy even in the presence of geometric degeneracies. However, due to its memory requiremen...
