inline

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.

dimy	Dimenson (number of points) in the second generation direction.
minxRef	Lower bound for the first parameter in the reference coordinate system.
maxxRef	Upper bound for the first parameter in the reference coordinate system.
minyRef	Lower bound for the second parameter in the reference coordinate system.
maxyRef	Upper bound for the second parameter in the reference coordinate system.
fx	Function that maps node coordinates of the reference grid to the first node coordinates of the actual grid.
fy	Function that maps node coordinates of the reference grid to the second node coordinates of the actual grid.
