3.11. Plcker's Conoid

[next]

The Plcker Conoid [ 6,11,18 ] is represented by the following equations.

 

x = u sqrt(1 - v 2 )

3-45

 

y = u v

3-46

 

z = 1 - v 2

3-47

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 [-2, 2]

 
 

v is an element from the number set [-1, 1]

 

The Plcker's Conoid is an open figure, so the definition range can be changed with the plugin.
