A user sketches coarse elevation, landcover, temperature, and precipitation directly onto a globe. Our model then infers high\u2010resolution heightmap and surface appearance layers at planetary scales, with sufficient detail to enable animated flyovers within the exosphere at a distance of a few thousand kilometers from the planet surface. We address the issue of distortion in the mapping from atlas to globe using a quadsphere representation, and the consistency of large\u2010scale geomorphological features by extracting a global river network from the sketch inputs and providing this as conditioning to the diffusion. As our results demonstrate, our generative model provides a balance between: authoring control through a multi\u2010layer painting interface with a satellite image pre\u2010visualization; computation times proportional to the surface area being generated; landscape diversity, displaying, without repetition artefacts, the full range of elevation and landcover features drawn from multiple source planets, and geomorphological plausibility through the provision of a consistent uninterrupted exorheic global river network, where the input sketches allow.<\/jats:p>","DOI":"10.1111\/cgf.70390","type":"journal-article","created":{"date-parts":[[2026,4,30]],"date-time":"2026-04-30T15:15:16Z","timestamp":1777562116000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Authoring Terrestrial Planets with Diffusion Models"],"prefix":"10.1111","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-7336-4372","authenticated-orcid":false,"given":"Oliver","family":"Borg","sequence":"first","affiliation":[{"name":"University of Cape Town  South Africa"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1699-9619","authenticated-orcid":false,"given":"James","family":"Gain","sequence":"additional","affiliation":[{"name":"University of Cape Town  South Africa"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2189-2728","authenticated-orcid":false,"given":"\u00c9ric","family":"Gu\u00e9rin","sequence":"additional","affiliation":[{"name":"Univ Lyon, INSA\u2010Lyon, CNRS, LIRIS  France"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6994-9164","authenticated-orcid":false,"given":"Adrien","family":"Peytavie","sequence":"additional","affiliation":[{"name":"Univ Lyon, Universit\u00e9 Lyon 1, CNRS, LIRIS  France"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7752-9031","authenticated-orcid":false,"given":"Marie\u2010Paule","family":"Cani","sequence":"additional","affiliation":[{"name":"LIX, Ecole Polytechnique\/CNRS, IP Paris  Palaiseau France"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5946-4112","authenticated-orcid":false,"given":"Eric","family":"Galin","sequence":"additional","affiliation":[{"name":"Univ Lyon, Universit\u00e9 Lyon 1, CNRS, LIRIS  France"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0124-0180","authenticated-orcid":false,"given":"Guillaume","family":"Cordonnier","sequence":"additional","affiliation":[{"name":"Inria, Universit\u00e9 C\u00f4te d'Azur  France"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2026,4,30]]},"reference":[{"issue":"2","key":"e_1_2_10_2_2","doi-asserted-by":"crossref","first-page":"101","DOI":"10.1111\/cgf.13345","article-title":"Terrain super-resolution through aerial imagery and fully convolutional networks","volume":"37","author":"Argudo O.","year":"2018","journal-title":"Computer Graphics Forum"},{"key":"e_1_2_10_3_2","unstructured":"AversaM.
