A Platonic solid, geodesically subdivided, drawn as 2D line art. Detail is subdivision; tilt is the viewing angle. Far side fades the hidden hemisphere so the solid reads in depth.
Start from a Platonic solid, subdivide each face toward a sphere, and project the vertices back out. What you see is a 2D line drawing of that mesh: tilt is the view, Far side fades the hidden hemisphere so the solid reads in depth.
