A hidden-line algorithm for displaying curved surfaces by line drawing is presented. The algorithm divides the screen plane into small rectangles, unlike Ohno's algorithm, which divides the screen space into small 3D boxes and exploits quadrilateral coherence and depth coherence. The present algorit

✦ Synopsis
Three algorithms for draping biaxially woven fabrics on arbitrarily curved surfaces are presented and compared for numerical accuracy and computational expense. The first one minimizes the elastic energy in each fabric cell, while the two others are based on placing a net of interlocked and inextensible fibres on the surface along geodesic lines. A benchmark shows that the minimum energy technique performs the best and is also the most promising for further optimization in terms of numerical quadrature formulae.

The paper presents pseudocode aloorithms, c-lanouaoe code, and error analysis for removino knots from rational B-spline curves and surfaces. Efficient and easy-to-use aloorithms are presented that, with one call, remove all the removable knots from a B-spline curve or surface.
The proposed algorithm d/splays the projected surface F as a quadrilateral grid of straight segments, g; any one of these can be part of the silhouette if, and only if, the two patches connected along g lie on the same side of it. The same segment g is drawn, if it is not hidden by remote patches. T
We propose an efficient algorithm for the refinement of curves and surfaces using simple knot B-splines. We develop a high speed algorithm for the computation of the \(r\) th derivative of an \(r\) th order spline and demonstrate that the inverse of this algorithm leads to an efficient refinement al
