Accelerated Evaluation of Box Splines via a Parallel Inverse FFT
(Blackwell Science Ltd and the Eurographics Association, 1996)Box splines are a multivariate extension of uniform univariate B-splines. Direct evaluation of a box spline basis function can he difficult but they have a relatively simple Fourier transform and can therefore be evaluated ... -
Animation of Human Diving
(Blackwell Science Ltd and the Eurographics Association, 1996)The motion of a human platform diver was simulated using a dynamic model and a control system. The dynamic model has 32 actuated degrees of freedom and dynamic parameters within the range of those reported in the literature ... -
An Efficient Algorithm for Line Clipping by Convex and Non-convex Polyhedra in E3
(Blackwell Science Ltd and the Eurographics Association, 1996)A new algorithm for clipping lines against convex polyhedron with O(N) complexity is given with modification for non-convex polyhedron. The suggested algorithm is faster for higher number of facets of the given polyhedron ... -
Fitting Triangular B-Splines to Functional Scattered Data
(Blackwell Science Ltd and the Eurographics Association, 1996)Scattered data is, by definition, irregularly spaced. Uniform surface schemes are not well adapted to the locally varying nature of such data. Conversely, Triangular B-Spline surfaces 2 are more flexible in that they can ... -
Scripting Interactive Physically-Based Motions with Relative Paths and Synchronization
(Blackwell Science Ltd and the Eurographics Association, 1996)This paper presents a novel approach for facilitating the use of physically based models by animators. The idea is to let the user guide motion at a high level of control by giving approximate desired trajectories and ... -
Surface Reconstruction from Unstructured 3D Data
(Blackwell Science Ltd and the Eurographics Association, 1996)Building 3 0 models from unstructured data is a problem that arises increasingly as new 30 scanning technology is able to produce large and complex databases of full 3 0 information. Huge efforts put into segmenting entire ...
