The only way I can see to do it currently with gnuplot is to do a 
delaunay triangulation of the patch (assuming its planar), deal with the 
convex/concave issues and  triangles outside the border of the original 
patch, and then plot it as if it was a set of triangles.. This is 
particularly messy and probably better to do something like this within 
gnuplot itself with the 3D equivalent of the 2D "filledcurve" option..
