The wave sphere [ 9 ] is represented by the following equations.
x = u cos(cos(u)) cos(v) 
3196 

y = u cos(cos(u)) sin(v) 
3197 

z = u sin(cos(u)) 
3198 
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 set of numbers [0, 14.5] 

v is an element of the number set [0, 2 pi] 
The domain of definition can be changed in the plugin.
Fig. 63 shows the sphere cut open so that the structure can be seen better.
