Mark Dearman shared some awesome 3D explorations on his Behance page titled Uncut Gems. The 3d work is a collection of generative crystals, exploring light and refraction. The core structures were created procedurally in Houdini, then textured in Substance Designer and finally, lit and animated in Cinema 4D.
As part of my creative process I spend a lot of time experimenting with 3D, exploring the juxtaposition of nature and technology.
