13 September 2009 10:10:11.899 AM TRIANGULATION_DELAUNAY_DISCREPANCY FORTRAN90 version Read a node dataset of NODE_NUM points in 2 dimensions. Read an associated triangulation dataset of TRIANGLE_NUM triangles using 3 or 6 nodes. Determine the Delaunay discrepancy, that is, the amount by which the minimum angle in the triangulation could be changed by a single adjustment of a pair of triangles. If this discrepancy is negative, then the triangulation is not a Delaunay triangulation. If this discrepancy is 0 or essentially so, then the triangulation is a Delaunay triangulation. Read the header of "ted3_nodes.txt". Spatial dimension DIM_NUM = 2 Number of nodes NODE_NUM = 10 Read the data in "ted3_nodes.txt".
