NVIDIA Just Solved The Hardest Problem in Physics Simulation!


Summary

This video showcases a cutting-edge computer simulation demonstrating the transition from winter to summer with incredible detail using two million triangles. It introduces the novel technique called Offset Geometric Contact (OGC) that provides digital objects with solidity to prevent penetration. OGC's personal sensors for objects enable free movement while maintaining prevention of undesirable penetration, offering a mathematical beauty in creating clean forces to ensure object solidity and realistic simulations. The video discusses OGC's efficiency in parallel processing on GPUs, its ability to handle complex simulations without issues like clothing showing through characters, and highlights its advantages compared to earlier techniques.
