Alex Roman made this video, The Third & The Seventh, using 3dsmax, Vray, AfterEffects and Premiere.
Every element of this short film is CGI (Computer-generated Imagery).

Roman describes it as "A FULL-CG animated piece that tries to illustrate architecture art across a photographic point of view where main subjects are already-built spaces. Sometimes in an abstract way. Sometimes surreal."

Whatever that means, Mind Blown.
