[pstricks] 3D surface

[1030115110 at erciyes.edu.tr]

Hello everyone,

I’m newbie on PsTricks. Could you help me what is the easiest way to make 3D 
surface like attached PDF. (2 pages. Colored & white shaded).

datax.dat, datay.dat and dataz.dat are 30x30 matrix (datas.zip). It is 
produced by matlab. PDF are also produced by matlab.


Matlab code:
x=linspace(-pi/2,pi/2,30);
y=x;
[x,y1]=meshgrid(x,y);
z1=sin(x1).*cos(y1);
surf(x1,y1,z1)

Thanks

Mustafa YILDIRIM
