3.34. Snail Surface

[next]

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

 

x = u cos(v) sin(u)

3-117

 

y = u cos(u) cos(v)

3-118

 

z = -u sin(v)

3-119

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.
