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.
z-emotion is a Seoul-based fashion-tech company building 3D garment simulation software that lets designers create true-to-life digital clothing in seconds. Its flagship CAD tool, z-weave, plus plugins for Autodesk Maya and Unreal Engine, a cloud asset library, and AI-driven virtual try-on, help fashion, gaming, and e-commerce companies replace physical samples with photorealistic 3D garments. Founded by former AMD graphics researcher Dongsoo Han, the company pairs game-grade simulation with apparel workflows to push the fashion industry toward digital production.
