Smooth contour line construction with spline interpolation.

Pere Brunet Crosa, Lluis Pérez Vidal (1984)

Qüestiió

Similarity:

Contour maps are frequently used to represent three-dimensional surfaces from geographical applications or experimental results. In this paper, two new algorithms for the generation and display of such contours are presented. The first of them uses local spline interpolation to obtain contour maps from data points in a rectangular mesh, whereas the other interpolates a set of irregular points through recursive subdivision of triangles. In both algorithms, precision of the contours can...

Similarity:

Tetrahedral finite C 0 -elements of the Hermite type satisfying the maximum angle condition are presented and the corresponding finite element interpolation theorems in the maximum norm are proved.
