New ABCD framework enables large radiance field training on limited VRAM

Researchers have introduced ABCD (Alpha-Composited Block Coordinate Descent), a novel out-of-core training framework designed for large radiance fields, specifically demonstrated with 3D Gaussian Splatting. This method optimizes memory usage by reformulating training into block coordinate descent, activating only one parameter block at a time. By pre-rendering and collapsing inactive regions into RGBA images, ABCD significantly reduces peak VRAM requirements, enabling training of extensive scenes on GPUs with limited memory. Experiments show that ABCD maintains high reconstruction quality, with less than a 5% degradation in peak signal-to-noise ratio compared to standard methods. AI

IMPACT Reduces VRAM requirements for training large radiance fields, potentially enabling wider adoption of advanced 3D rendering techniques.
