Hello World,


  I am looking for "drawing" a 2D surface (e.g. Z(x,y)) where in somewhere in this 
surface, I would like to get a 1/4-ellipsoid shape. 

Starting with a space increment in X-axis and Y-axis, I would like to discretize 
my half-ellipsoid equation and put it into my 2D surface as shown on fig.

Thanks for your help
