Performance of the triangulation-based methods Of positivity-preserving scattered data interpolation
We present the result and accuracy comparison of generalized positivity-preserving schemes for triangular Bézier patches of 1C and 2C scattered data interpolants that have been c on structed. We compare three methods of 1C schemes using cubic triangular Bézier patches and one 2C scheme using quint...

| 總結: | We present the result and accuracy comparison of generalized positivity-preserving schemes for triangular Bézier patches of 1C and 2C scattered data interpolants that have been c
on structed. We compare three methods of 1C
schemes using cubic triangular Bézier patches and one 2C scheme using quintic triangular Bézier patches.Our test case consists of four sets of node/test function pairs, with
node-count ranging from 26 to 100 data
points. The absolute maximum and mean errors are computed using 33×33 evaluation points on a uniform rectangular grid. |
