Lightplane is bit like Flash Attention for NeRF: efficient fused kernels for volume rendering (3D -> 2D) and feature lifting (2D -> 3D) that drastically reduce memory usage over naive implementations. Code is open-source, so try dropping it into your own 3D models!

Excited to release Lightplane: A highly memory-efficient differentiable NeRF renderer and feature splatter. It renders FullHD image batches using <1GB of GPU memory and greatly scales up 3D deep models such as the Large Reconstruction Model.
