[size=85] A [url=https://en.wikipedia.org/wiki/Snub_(geometry)]snub[/url]-operation can be seen by moving the slider [i]t[/i] (0≤t≤1) for expanding faces of a polyhedron : t=0 satisfy Dodecahedron, t= 0.632785313013558 [url=http://dmccooey.com/polyhedra/Rhombicosidodecahedron.html]Rhombicosidodecahedron[/url] and t=0 -Icosahedron. You can use the slider [b]α[/b] to set the rotation of faces relative to their centers and under certain conditions to get: [url=http://dmccooey.com/polyhedra/RsnubDodecahedron.html]Snub Dodecahedron[/url].[/size]
