Ellipsoid Triangulation and Cropping

Ellipsoid triangulation and cropping

This function generates triangulation for an ellipsoid from icosahedron and crops the triangulation inside a box. Example file is provided.

function [VV,FF]=Crop_Ellipsoid_Triangulation(x,y,z,Ellipsoid,N)

Input:

x=[x1 x2]: x boundaries of the box

y=[y1 y2]: y boundaries of the box

z=[z1 z2]: z boundaries of the box

Ellipsoid is (1*9) array. each cell represent:

(1): radius of ellipsoids at direction 1

(2): radius of ellipsoids at direction 2

(3): radius of ellipsoids at direction 3

(4): x-cooridante of centroid

(5): y-coordinate of centroid

(6): z-coordinate of centroid

(7): Inclination angle 1

(8): Inclination angle 2

(9): Inclination angle 3

N: frequency of subdivison

Output:

VV: vertices matrix

FF: faces matrix
