3.49. Stiletto Surface


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


x = (2+cos(u)) cos(v) cos(v) cos(v) sin(v)



y = (2+cos(u+2pi/3)) cos(v+2pi/3) cos(v+2pi/3) sin(v+2pi/3) sin(v+2pi/3 )



z = -(2+cos(u-2pi/3)) cos(v+2pi/3) cos(v+2pi/3) sin(v+2pi/3) sin(v+2pi/ 3)


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 [0, pi]


Since the Stiletto Surface is a closed figure, the definition range must be adhered to exactly, it cannot be changed with the plugin.
