CRESSim-Neo - simulation engine for surgical robotics and robot learning

 

"We are excited to release CRESSim-Neo, a new open-source, GPU-accelerated simulation engine for surgical robotics and robot learning.

CRESSim-Neo uses position-based dynamics (PBD) and supports simulation of rigid bodies, deformable tissue, fluids, and strands. It also provides surgery-specific capabilities including suturing, suction, cauterization, and simulated ultrasound.

The engine is designed with an emphasis on minimalism, high-performance GPU simulation, cross-platform and cross-GPU portability, modern graphics APIs, HLSL-based shading, and tight graphics-compute interoperability.
