I would like to make a surface that obeys the equation:
z = Asin(x) + Asin(y), 0<=z<=1; 0<=x<=2npi; 0<=y<=2npi
Where I would like to be able to change n to increase/decrease the number of cycles and change the amplitude A. I attempted to generate a sine wave via a script that I found; then I tried to extrude it, duplicate it, and then rotate one of the planes so that they intersected at a 90degree angle. The results were not very satisfying...
