# Dongsoo Han

> Dongsoo Han is the founder and CEO of z-emotion, a 3D garment simulation company building software that lets fashion brands design, fit, and render clothing entirely in 3D. A computer graphics engineer with 25+ years in simulation and gaming, he built the hair physics that became AMD's TressFX, the first playable real-time hair in a video game (Tomb Raider). He later realized a thread in 3D space moves much like a strand of hair, and turned that insight into z-emotion's products z-weave, z-fit, z-maya, and zeavric, used in projects with brands like Louis Vuitton and Nike.
