  \psSurface[fillcolor=cyan!10,%algebraic,%axesboxed,
   ngrid=.25 .25,incolor=yellow,linewidth=0.125\pslinewidth,grid,
   intersectionplan={[0 0 1 -8.4] [0 0 1 -3.6] [1 -1 0 0]},
   intersectioncolor=(blue) (red) (green),%english names with last update
   intersectionlinewidth=1  1 1,
   intersectiontype=0](-3,-3)(15,15){ x 4 sub dup mul y 4 sub dup mul 
add -5 div 10 add
     dup -2 lt {pop -2}if }
