- Developed a real-time cutting simulation using PBD and ISPCs in Unity 3D. Applied hybrid CPU–GPU processing to accelerate cutting and deformation.
- Achieved real-time performance in 7 of 8 tested 3D models. Improved frame rates by up to 677% compared to previous methods. Maintained volume preservation within 0.4% for simple models.
- Improved the efficiency and stability of real-time cutting simulations. Demonstrated potential applications in VR/AR surgical training and soft-tissue simulation.
