Learning Neural Light Transport
In recent years, deep generative models have gained significance due to their
ability to synthesize natural-looking images with applications ranging from
virtual reality to data augmentation for training computer vision models. While
existing models are able to faithfully learn the image distribution of the
training set, they often lack controllability as they operate in 2D pixel space
and do not model the physical image formation process. In this work, we
investigate the importance of 3D reasoning for photorealistic rendering. We
present an approach for learning light transport in static and dynamic 3D
scenes using a neural network with the goal of predicting photorealistic
images. In contrast to existing approaches that operate in the 2D image domain,
our approach reasons in both 3D and 2D space, thus enabling global illumination
effects and manipulation of 3D scene geometry. Experimentally, we find that our
model is able to produce photorealistic renderings of static and dynamic
scenes. Moreover, it compares favorably to baselines which combine path tracing
and image denoising at the same computational budget.Comment: 31 pages, 17 figure
Evaluating potential effects of solar power facilities on wildlife from an animal behavior perspective
Solar power is a renewable energy source with great potential to help meet increasing global energy demands and reduce our reliance on fossil fuels. However, research is scarce on how solar facilities affect wildlife. With input from professionals in ecology, conservation, and energy, we conducted a research-prioritization process and identified key questions needed to better understand impacts of solar facilities on wildlife. We focused on animal behavior, which can be used to identify population responses before mortality or other fitness consequences are documented. Behavioral studies can also offer approaches to understand the mechanisms leading to negative interactions (e.g., collision, singeing, avoidance) and provide insight into mitigating effects. Here, we review how behavioral responses to solar facilities, including perception, movement, habitat use, and interspecific interactions are priority research areas. Addressing these themes will lead to a more comprehensive understanding of the effects of solar power on wildlife and guide future mitigation
