Why would anyone build with this?

REASON 1

Turn a short video of a person or animal moving into an animated 3D mesh for a game or film.

REASON 2

Animate an existing 3D model by feeding it a reference video, keeping its texture and structure intact.

REASON 3

Prototype character animation quickly without manually sculpting or keyframing motion.

REASON 4

Test the tool on Google Colab's free-tier GPU using low-RAM mode before investing in dedicated hardware.
