down vote favorite How can I create a Triangulated sphere with faces of triangles with the same area each one.

I want something like this,

and I searched and I saw I could use the function isosurfaceof MATLAB, but the triangles are not equal and the are essestially squares divided in two with the square diagonal.

here's my code:

>> [X,Y,Z] = meshgrid(-10:10,-10:10,-10:10);

>> V = sqrt(X.^2+Y.^2+Z.^2);

>> fv = isosurface(X,Y,Z,V)

>> p = patch(fv);

>> set(p,'EdgeColor','g')

and the result is below:

The area of a triangle depends on the 3 points of it. So if your data points are not uniformly distributed, then you shall not expect triangles of the same size.
