Not a Hair Out of Place: Neural Physics Enables Realistic Simulations

An NVIDIA research paper showcases a method that can simulate tens of thousands of hairs in high resolution and in real time using neural physics, an AI technique that teaches a neural network to predict how an object would move in the real world. The teams novel approach for accurate simulation of fullscale hair is specifically optimized for modern GPUs. It offers significant performance leaps compared to stateoftheart, CPUbased solvers, reducing simulation times from multiple days to merely hours while also boosting the quality of hair simulations possible in real time. This technique finally enables both accurate and interactive physically based hair grooming.
