Embedding polygonal mesh assets within photorealistic Neural Radience Fields (NeRF)
volumes, such that they can be rendered and their dynamics simulated in a physically …

Urban areas are a high-stake target of climate change mitigation and adaptation measures.
To understand, predict, and improve the energy performance of cities, the scientific …

We present a method for reducing errors---variance and bias---in physically based
differentiable rendering (PBDR). Typical applications of PBDR repeatedly render a scene as …

Photorealistic rendering of the virtual world is an important and classic problem in the field of
computer graphics. With the development of GPU hardware and continuous research on …

Volumetric representations are popular in inverse rendering because they have a simple
parameterization, are smoothly varying, and transparently handle topology changes …

Partial differential equations (PDEs) with spatially varying coefficients arise throughout
science and engineering, modeling rich heterogeneous material behavior. Yet conventional …

Volume rendering under complex, dynamic lighting is challenging, especially if targeting
real-time. To address this challenge, we extend a recent direct illumination sampling …

The unique and visually mesmerizing appearance of pearlescent materials has made them
an indispensable ingredient in a diverse array of applications including packaging …

The complex interplay of a number of physical and meteorological phenomena makes
simulating clouds a challenging and open research problem. We explore a physically …

Computing the light attenuation between two given points is an essential yet expensive task
in volumetric light transport simulation. Existing unbiased transmittance estimators are all …
