Atlas: city-scale 3D scenes on a mobile GPU

City-scale 3D scenes exceed mobile GPU memory. A preprint by He Zhu and colleagues, posted to arXiv on September 2, addresses the problem with hierarchical offload, temporal level-of-detail and stereo rasterisation.

The work matters for offline spatial computing.

The authors report an 18.5x speed-up and 92.4 per cent energy saving; the figures are author-reported.
