On the parameterization of Catmull-Rom curves
TL;DR: This paper proves that, for cubic Catmull-Rom curves, centripetal parameterization is the only parameterization in this family that guarantees that the curves do not form cusps or self-intersections within curve segments, and provides a formulation that bounds the distance of the curve to the control polygon.
Proceedings ArticleDOI
Simulation levels of detail for plant motion
J. Beaudoin,John Keyser +1 more
TL;DR: A method for simulating motion of realistically complex plants interactively using a precomputation stage to generate the plant structure, along with a set of simulation levels of detail, which can significantly improve simulation times for complex trees.
Journal ArticleDOI
Efficient and accurate B-rep generation of low degree sculptured solids using arithmetic: II—computation
TL;DR: E cient algorithms for exact boundary computation on low degree sculptured CSG solids using exact arithmetic are presented, including algorithms for computing the intersection curves of low-degree trimmed parametric surfaces.

Boole: a boundary evaluation system for boolean combinations of sculptured solids
TL;DR: A system, BOOLE, that generates the boundary representations (B-reps) of solids given as a CSG expression in the form of trimmed Bezier patches using the exact representation of the intersection curve to facilitate an accurate boundary evaluation at every Boolean set operation and generation of topologically consistent solids.
