3.34. Snail Surface


The snail surface [ 8 ] is represented by the following equations.


x = u cos(v) sin(u)



y = u cos(u) cos(v)



z = -u sin(v)


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, 2 pi]


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


The domain of definition can be changed in the plugin.
