void | GenerateCoordinates (int dimx, int dimy, double minxRef, double maxxRef, double minyRef, double maxyRef, IFunc2d fx, IFunc2d fy) |
Generates coordinates of an (unconnected) unstructured grid of points based on coordinates of a structured mesh for a parametric volume according to functions specifying the x, y, and z coordinates in terms of three scalar functions of 3 variables. Coordinates are obtained by mapping individual coordinates of a regular equidistant grid from the reference system. |
