AI Summary

Overview

ZOZO's Contact Solver is a high-performance, GPU-accelerated physics simulation engine designed for complex scenarios involving deformable shells, rigid solids, and articulated rods. Developed by ZOZO, Inc., Japan's leading fashion e-commerce company, this solver delivers robust, scalable, and cache-efficient contact resolution for demanding simulation tasks. It offers flexible deployment options, including native Windows executables, Docker containers, and a user-friendly Blender add-on, making it accessible for both individual developers and enterprise solutions.

Key Features

Robust Contact Resolution: Ensures penetration-free and snag-free simulations, maintaining the integrity of physical interactions.
Exceptional Scalability: Capable of handling massive simulation scenarios with upwards of 180 million contacts, far exceeding typical million-contact limits.
GPU-Optimized Performance: Leverages the power of modern NVIDIA GPUs for both contact and elasticity solvers, ensuring high throughput and efficient computation using single precision.
Finite Element Method (FEM): Employs FEM for accurate simulation of deformable objects and utilizes symbolic force Jacobians for precise calculations.
User-Friendly Interfaces: Offers a seamless experience through a dedicated Blender add-on for intuitive scene creation and simulation control, and JupyterLab for programmatic control and scripting.
Cross-Platform Compatibility: Supports native Windows executables (no installation required) and Docker for Linux and Windows environments, simplifying deployment.
Blender Add-on for macOS: Enables powerful remote simulation and results fetching even on macOS systems, without requiring local NVIDIA hardware.
Flexible Deployment: Easily deployable on major cloud platforms and integrates with LLMs for natural language-driven simulation control (MCP Support).
Permissive Licensing: Released under Apache 2.0 license, allowing for commercial and proprietary use.
