Feature-Adaptive GPU Rendering of Catmull-Clark Subdivision Surfaces

A hardware tessellation-based algorithm for rendering Catmull-Clark subdivision surfaces that fully complies with the RenderMan specification. Though considerably more general, the performance of the algorithm is comparable to the best approximating method and considerably faster than Stam's exact method.

Discrete Bi-Laplacians and Biharmonic B-Splines

This paper presents bivariate B-splines with well-behaving properties by using discrete Laplace operators. The resulting splines possess a fully irregular, discrete refinement scheme that generalizes knot insertion for univariate B-splines.

Perceptual Models of Viewpoint Preference

A general model of 3D viewpoint goodness using attributes like projected area and silhouette length. The model is trained on a large user study. The paper demonstrates several applications, such as automatically selecting a good set of representative views and optimizing camera orbits.
