QuickSurface(x, y, z, c, anObject) produces a 3-d view of a 2-dimensional surface.

z may be either a matrix,, or a string, a valid formula of the x and y variables.

c may be a list, an array of real, a matrix, 0, or a string, the name of a SmileLab color palette.

Except for the additional parameter c, the syntax for QuickSurface is the same as for QuickScalarMap.

QuickSurface("2*pi*x*cos(2*pi*y)", "2*pi*x*sin(2*pi*y)", "cos(2*pi*x+10*pi*y)", 0, 0)
