3.35. Cosine Surface


The cosine surface [ 11 ] is represented by the following equations.


x = cos(u)



y = cos(v)



z = cos(u + v)


The cosine surface is the counterpart to the sine surface .

To represent the area, the two parameters u and v can assume the following values ​​(domain of definition), for example.


u is an element from the number set [-pi, pi]


v is an element from the number set [-pi, pi]


Since the cosine surface is a closed figure, the definition range must be adhered to exactly, it cannot be changed with the plugin.
