3.35. Cosine Surface

[next]

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

 

x = cos(u)

3-120

 

y = cos(v)

3-121

 

z = cos(u + v)

3-122

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.
