A GPU-accelerated contact solver for physics-based simulations of shells (cloth), solids, rods, rigid bodies, and sand, originally developed in-house at ZOZO, Inc. It provides a Python API, a Blender add-on for remote simulation, and Docker-based setup for running examples.

Use cases

• simulate cloth and garment physics on GPU
• resolve contacts between rigid bodies without penetration
• simulate rods, solids, and granular sand materials
• run physics simulations from Blender
• simulate large-scale scenes with hundreds of millions of contacts

When to choose

• you need penetration-free contact resolution for cloth or deformable bodies
• you need GPU-accelerated physics with very large contact counts
• you want to simulate garments for fashion or e-commerce visualization
• you want a Blender-integrated physics solver

When to avoid

• you need a general-purpose game engine with rendering and audio
• you have no NVIDIA GPU and cannot use Docker
• you need CPU-only double-precision simulation
• you need soft-body physics beyond shells, solids, rods, rigid bodies, and sand
