Hello Jessica,

I used the software simplex numerica for 3D plots. You can
download the demo version from www.simplexnumerica.com. To
get the full version you must buy a license, it is possible to buy it
online.

If you want to have a look at my 3d plots, you can find it in Europ.
Food Res. and Technology  Volume 220 No. 2 p.232.

Regards Jochen
