I started playing around in Octane for C4D, here are some renders studies. Im incredibly impressed by how fast it renders for its visual output.
Circles are beautiful
Octahedral Pyramid
In 4-dimensional geometry, the octahedral pyramid is bounded by one octahedron on the base and 8 triangular pyramid cells which meet at the apex. Since an octahedron has a circumradius divided by edge length less than one, the triangular pyramids can made with regular faces (as regular tetrahedrons) by computing the appropriate height.
