Before this workshop, many designers in China, especially motion or graphic designers, expressed their desire to design real-time physical text graphics. That's where this workshop comes in! 

To meet this demand, I'll be introducing the Bullet API in TouchDesigner to create interactive physical typography. The workshop will be conducted online and available in Chinese initially. However, I've noticed a growing interest from overseas individuals, so I've decided to translate the entire recording and post it on Patreon to make it accessible to every creator in the TouchDesigner community!

  1. Latest TouchDesigner Version - 2024.11600.
  2. Compacity both of Window and Mac.



  1. These videos weren't released until I had translated them. (maybe the mid of April)
  2. Even though the workshop is recorded, it still provides technique Q&A in Discord.
  3. in this session,I only teach simulation for rigid body, instead of fluid and sofe bodies.
  4. if you created nice works please credit my workshop to support me in constantly share knowledge with you!
