Superformula by LuxXeon ()
Modeled entirely in 3dsmax. Rendered in Luxrender.
A combination of renderable splines and some mathematically-driven Maxscript formula. The shape is derived from several geospheres linked together mathematically, and the edges extracted, and converted to renderable splines. It's a spline-based replica of a 24-cell truncated polyhedra object in 4D space.
