The difficulty is keeping a model physically meaningful while running it over an entire catchment or dune field, which rules out direct numerical simulation. These models are designed with geophysicists and geomorphologists, so that what they produce reads as a plausible history of the terrain and not only as a plausible image of it. https://perso.liris.cnrs.fr/apeytavi/website/publication/hal-04090644/ Sun, 01 Jan 2023 00:00:00 +0000 https://perso.liris.cnrs.fr/apeytavi/website/publication/hal-04090644/ We introduce the first solution for simulating the formation and evolution of glaciers, together with their attendant erosive effects, for periods covering the combination of glacial and inter-glacial cycles. Our efficient solution includes both a fast yet accurate deep learning-based estimation of highorder ice flows and a new, multi-scale advection scheme enabling us to account for the distinct time scales at which glaciers reach equilibrium compared to eroding the terrain. https://perso.liris.cnrs.fr/apeytavi/website/publication/hal-02929531/ Wed, 01 Jan 2020 00:00:00 +0000 https://perso.liris.cnrs.fr/apeytavi/website/publication/hal-02929531/ Glaciers are some of the most visually arresting and scenic elements of cold regions and high mountain landscapes. Although snow-covered terrains have previously received attention in computer graphics, simulating the temporal evolution of glaciers as well as modeling their wide range of features has never been addressed.
