We propose a compact vector\u2010based representation that models terrain as nested iso\u2010contours, inspired by geomorphology and cartography. Our method departs from traditional grid\u2010based elevation models by generating contours through an inward Open Eden Growth simulation, followed by marching\u2010triangles reconstruction into a Triangulated Irregular Network. This contour framework supports direct editing such as warping, slope modulation, and smoothing, while allowing reconstruction of a standard elevation map for downstream processing, including erosion and amplification. The approach enables the creation of diverse, realistic terrains from minimal user input and offers simple yet powerful control for designers.<\/jats:p>","DOI":"10.1111\/cgf.70389","type":"journal-article","created":{"date-parts":[[2026,4,30]],"date-time":"2026-04-30T15:03:43Z","timestamp":1777561423000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Terrain Synthesis and Authoring based on Iso\u2010Contours"],"prefix":"10.1111","author":[{"ORCID":"https:\/\/orcid.org\/0009-0002-4726-9392","authenticated-orcid":false,"given":"B.","family":"Huftier","sequence":"first","affiliation":[{"name":"LIRIS, Universit\u00e9 Claude Bernard Lyon 1, CNRS  France"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1281-977X","authenticated-orcid":false,"given":"H.","family":"Schott","sequence":"additional","affiliation":[{"name":"LIRIS, Universit\u00e9 Claude Bernard Lyon 1, CNRS  France"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5946-4112","authenticated-orcid":false,"given":"E.","family":"Galin","sequence":"additional","affiliation":[{"name":"LIRIS, Universit\u00e9 Claude Bernard Lyon 1, CNRS  France"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3943-1839","authenticated-orcid":false,"given":"O.","family":"Argudo","sequence":"additional","affiliation":[{"name":"Universitat Polit\u00e8cnica de Catalunya  Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6994-9164","authenticated-orcid":false,"given":"A.","family":"Peytavie","sequence":"additional","affiliation":[{"name":"LIRIS, Universit\u00e9 Claude Bernard Lyon 1, CNRS  France"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2189-2728","authenticated-orcid":false,"given":"E.","family":"Gu\u00e9rin","sequence":"additional","affiliation":[{"name":"LIRIS, INSA\u2010Lyon, CNRS  France"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2026,4,30]]},"reference":[{"issue":"6","key":"e_1_2_9_2_2","doi-asserted-by":"crossref","first-page":"1005","DOI":"10.1007\/s00371-017-1393-6","article-title":"Coherent multi-layer landscape synthesis","volume":"33","author":"Argudo O.","year":"2017","journal-title":"The Visual Computer"},{"issue":"6","key":"e_1_2_9_3_2","doi-asserted-by":"crossref","DOI":"10.1145\/3355089.3356535","article-title":"Orometry-based terrain analysis and synthesis","volume":"38","author":"Argudo O.","year":"2019","journal-title":"ACM Transactions on Graphics"},{"issue":"2","key":"e_1_2_9_4_2","doi-asserted-by":"crossref","DOI":"10.1111\/cgf.70080","article-title":"Terrain descriptors for landscape synthesis, analysis and simulation","volume":"44","author":"Argudo O.","year":"2025","journal-title":"Computer Graphics Forum"},{"issue":"2","key":"e_1_2_9_5_2","doi-asserted-by":"crossref","first-page":"165","DOI":"10.1111\/cgf.12820","article-title":"Large scale terrain generation from tectonic uplift and fluvial erosion","volume":"35","author":"Cordonnier G.","year":"2016","journal-title":"Computer Graphics Forum"},{"key":"e_1_2_9_6_2","doi-asserted-by":"crossref","first-page":"27","DOI":"10.1109\/VISUAL.1998.745281","volume-title":"Proceedings of Visualization (Cat.
