Sketchfab 3D Scanning Challenge: Jack-o'-Lanterns

Back to overview

As we wade deeper into October, we see a light flickering in the distance. With our feet sinking into the bog, sticking hard with each step, we see what looks like a disembodied head with glowing eyes! But, wait, it’s just a jack-o’-lantern. Phew. But who left it here? Far from civilization, stuck knee-deep in a bog, there’s only one thing to be done: make a 3D scan of the glowing gourd.

UPDATE: Winner – Jack o’ lantern by threedex
