Unbelievable! Japan’s fashion giant ZOZO has open-sourced their top-tier physics engine for virtual clothing try-ons — ppf-contact-solver (contact solver)!
For anyone working in virtual fashion, digital garments, movie VFX, or even game physics, this is a free pass to an industrial-grade tool!
This engine specializes in handling contact and collision problems for fabrics, ropes, and soft bodies — zero penetration,
fabric stretching strictly respects physical limits, and a single scene can handle up to 180 million contact points!
Just look at the video: curtains swaying, ropes knotting, soft toys piling up, fabric twisting wildly — all buttery smooth and natural, just like the real world.
Available now:
- Blender Plugin
- JupyterLab Notebook interface
- GPU acceleration — high precision offline simulation.

@servasyy_ai: The physics calculations that 3D developers have practiced for years can now be done with just a single sentence. A free tool has been released that generates complex 3D particle effects from English instructions and can immediately output React or three.js code. The barriers of math and physics engines have disappeared, ushering in an era of instantly transforming ideas into reality. Experience
A free tool has been released that can generate complex 3D particle effects from English instructions and directly output React or three.js code, lowering the barrier to 3D physics calculations.
@AYi_AInotes: Everyone is raving about Japan's Fugu beating GPT on benchmarks, but I bet 99% of people haven't understood what really makes it mind-blowing. First off, this isn't some giant monolithic model at all—it has only 0.6B parameters and essentially works as an AI project manager. It handles simple tasks on its own, automatically splits complex ones, and selects the most suitable models from a global pool of top-tier models...
Sakana AI releases Fugu, a multi-agent orchestration system with only 0.6B parameters. By intelligently splitting tasks and coordinating multiple models, it achieves state-of-the-art performance while bypassing traditional parameter scaling. This marks the transition of multi-agent orchestration from a lab curiosity to a practical productivity tool.
