3d graph more precisely a 3D curve plotting

I would like to know the better mean to plot a 3D curve with VB4 Pro.

For example the curve Z= sin(x)*cos(y) with -3<x<3 and -3<y<3.

I would like to obtain the same result than Mathematica or Matlab with the

instruction mesh(x,y,z).

Or also the possibility to interconnect Vb4 Pro with gnuplot.

I' m interesting by code source *.bas or VBX or OCX files

Can you send me information about this subject?

Sincerely,

ps:sorry for my english.
