[back]  3.44. horn 
[next] 
The horn [ 8 ] is represented by the following equations.
x = (a + u cos(v)) sin(b pi u) 
3147 

y = (a + u cos(v)) cos(b pi u) + cu 
3148 

z = u sin(v) 
3149 
The constants a, b and c determine the appearance of the figure.
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, 1] 

v is an element from the number set [pi, pi] 
The domain of definition cannot be changed in the plugin.
The plugin creates an optimized mesh without duplicate points and unconnected polygons.
