3.50. Apple Surface


The Apple Surface [ 8 ] is represented by the following equations.


x = cos(u) (4 + 3.8 cos(v))



y = sin(u) (4 + 3.8 cos(v))



z = (cos(v)+sin(v)-1) (1+sin(v)) log(1-pi v/10)+7.5 sin(v)


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, pi]


The domain of definition cannot be changed in the plugin.
The plugin creates an optimized mesh without duplicate points and unconnected polygons.
