Lightplane: Highly-Scalable Components for Neural 3D Fields
arxiv(2024)
摘要
Contemporary 3D research, particularly in reconstruction and generation,
heavily relies on 2D images for inputs or supervision. However, current designs
for these 2D-3D mapping are memory-intensive, posing a significant bottleneck
for existing methods and hindering new applications. In response, we propose a
pair of highly scalable components for 3D neural fields: Lightplane Render and
Splatter, which significantly reduce memory usage in 2D-3D mapping. These
innovations enable the processing of vastly more and higher resolution images
with small memory and computational costs. We demonstrate their utility in
various applications, from benefiting single-scene optimization with
image-level losses to realizing a versatile pipeline for dramatically scaling
3D reconstruction and generation. Code:
