Tech stack & purpose

Mountains is a web-based terrain rendering engine for visualizing landscapes from Digital Elevation Models, currently showcasing the French Alps. The application is written primarily in OCaml, compiled to JavaScript and WebAssembly via `js_of_ocaml` and `wasm_of_ocaml`, and rendered using WebGL for modern browsers, with legacy support for a native desktop client using SDL2 and OpenGLES 3.0. It features advanced rendering techniques including radial clipmaps for level-of-detail, cascaded shadow maps, atmospheric effects, and triplanar texturing, along with mobile support including device orientation control and geolocation. The project includes a comprehensive data pipeline for processing CORINE Land Cover data, Digital Elevation Models from Copernicus and RGE ALTI, and water bodies from OpenStreetMap, built with the Dune build system.
