3D Terrain Mesh (STL/GLB/OBJ/PLY/glTF)
Open Betaמודל שטח תלת-ממדי — משטח תבליט הנבנה ממודל הגובה הגלובלי Copernicus GLO-30 (30 מ') ונשמר בפורמט תלת-ממד: STL להדפסת תלת-ממד, GLB/glTF לאינטרנט ול-Three.js, OBJ ל-Blender/3ds Max, PLY ל-MeshLab. שילוש גבהים סדיר עם פרמטר הגזמה אנכית (z-exaggeration 0.1–10) מאפשר להדגיש את התבליט אף בשטח שטוח. עובד בכל העולם, כולל הקוטב הצפוני.

אודות פורמט 3D Terrain
3D Terrain is not a map but a relief surface: a triangle mesh built from the Copernicus GLO-30 digital elevation model with a step of about 30 meters. There are no roads, buildings or labels here — only the shape of the land over the area you chose.
Such a model is taken when the terrain has to be touched or shown as a volume: printing a scale model of a valley, dropping relief under a scene in Blender, explaining the layout of a watershed to students. The elevation data covers the whole world, polar latitudes included.
The output format is chosen at export time: GLB and glTF for the web and Three.js, STL for slicers, OBJ for Blender and 3ds Max, PLY for MeshLab. Mesh density is picked automatically to match the area — the target is around 250 thousand vertices, with a hard ceiling of a million so the file still opens. Vertical exaggeration is set by a factor from 0.1 to 10: on flat land the relief is barely readable without it.
The result is an open surface, not a closed volume: it has no bottom and no side walls. For printing it is usually completed — you add a base in an editor or a slicer, otherwise the model will stand on the bed on a thin edge.

כיצד לייצא 3D Terrain
איך לפתוח לאחר הייצוא
- Blender — File → Import and the format you need (glTF, OBJ, PLY, STL); the model arrives in meters, and the scale can be checked against the object dimensions in the properties panel.
- Cura or PrusaSlicer — open the STL, put it on the bed, add a base; thin edges are better cut off, otherwise printing starts in mid-air.
- MeshLab — open the PLY or OBJ for cleanup: removing degenerate triangles, decimation, smoothing before printing or rendering.
- Three.js — the GLB loads through GLTFLoader and goes into the scene as is; the file is already binary and needs no extra packing.
- Closing the model before printing — in Blender (the Solidify modifier) or in Meshmixer: the surface turns into a volume with a bottom, after which the slicer handles it correctly.
