3.38. Kidney Surface


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


x = cos(u) (3 cos(v) - cos(3v))



y = sin(u) (3 cos(v) - cos(3 v))



z = 3sin(v) - sin(3v)


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/2, pi/2]


Since the Kidney Surface is a closed figure, the definition range must be adhered to exactly, it cannot be changed with the plugin.
The plugin creates an optimized mesh without duplicate points and unconnected polygons.
