Truncated Triacontahedron by TaffGoch Truncated Triacontahedron by TaffGoch
Here's a unique polyhedron, with which I've been experimenting It is a truncated medial rhombic triacontahedron

A triacontahedron has 30 faces A "medial" triacontahedron is a stellated polyhedron, with 30 rhombic faces that extend through the center of the object In a medial polyhedron, a face extends from one of the nodules, passing near (but not precisely through) the center, to an opposing nodule The "concave" edges closest to the center of the figure are considered "false" edges, as they are formed by the intersection of two intersecting "true" medial faces

A medial rhombic triacontahedron is stellated, having "pointy" vertices, at the outer extents These "pointy" extents have been truncated, to produce the outer-most pentagonal faces

While it, simply, looks like 12 clustered dodecahedra, the dodecahedral nodules are not regular, equilateral dodecahedra The nodules do, indeed, have equilateral edges, but all of the faces are not "regular" pentagons Only the outer-most pentagons are equilateral and regular All other pentagons are "squashed" a bit, producing different vertex angles (The vertex angles aren't all 108, as in a "regular" pentagon)

I've revised the deviation, to include a second, textured version of the polyhedron, for deviants who are having difficulty visualizing the geometry

fascinating object! :o the depth of field quality could be better though :sherlock:

is this object in the sketchup warehouse?

Perhaps, you're referring to the "granularity" of the blur.

I didn't run the render at high-quality, which would have softened the blur, since I intended to only present a quick render, to introduce other deviants to the polyhedron (which I haven't, myself, seen elsewhere)

Are you suggesting more blur, or less?

The Medial Rhombic Triacontahedron is, indeed, in the 3D Warehouse (but not the truncated version)
