[back] | 3.20. helicoid |
[next] |  |
The helicoid [ 3,11 ] is represented by the following equations.
|
x = u cos(v) |
3-74 |
|
|
y = u sin(v) |
3-75 |
|
|
z = cv |
3-76 |
The constant c determines 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 [-2.0, 2.0] |
||
|
v is an element of the number set [0, 2pi] |
The helicoid is a half-open figure, so the domain of u can be changed in the plugin.
