NeRF as Non-Distant Environment Emitter in Physics-based Inverse Rendering

no code implementations7 Feb 2024 Jingwang Ling, Ruihan Yu, Feng Xu, Chun Du, Shuang Zhao

While the environment map is commonly used as the lighting model in inverse rendering, we show that its distant lighting assumption leads to spatial invariant lighting, which can be an inaccurate approximation in real-world inverse rendering.

Reduced Dynamics and Control for an Autonomous Bicycle

no code implementations30 Mar 2021 Jiaming Xiong, Bo Li, Ruihan Yu, Daolin Ma, Wei Wang, Caishan Liu

In this paper, we propose the reduced model for the full dynamics of a bicycle and analyze its nonlinear behavior under a proportional control law for steering.
