h2. Examples

h3. Ex.1: Contouring of 3d surfaces in a cube

{noformat:|borderWidth=1|bgColor=#eeeeee}
        # generate cube and display 3D contours
        mak ran 11   ;#  make 11 random points
        gr3 12 12 12 ;#  make cube of dimension 12 x 12 x 12
        dis opa .3   ;#  display cube with opacity .3
        c3d n 4      ;#  contour 4 iso surfaces
{noformat}
