COLLADA/DAE (3D Exchange)
Open Beta3D-hoonete eksport COLLADA-vormingusse (.dae) 3D-andmevahetuseks. XML-vorming, mida toetavad Blender, SketchUp ja Google Earth. Sisaldab materjale, mille värvid sõltuvad hoonetüübist.
Põhiomadused
Vormingu COLLADA kohta
COLLADA (.dae) is an open XML format for exchanging 3D scenes, standardized by the Khronos Group and adopted as ISO/PAS 17506. It is older and heavier than glTF, but it remains the most reliable common language between SketchUp, Blender, Maya, 3ds Max and Google Earth — it is read practically everywhere, including old versions of programs.
A map is exported to DAE when city development is needed as an object in someone else's scene: to drop the context around a project into SketchUp, to assemble a 3D model for Google Earth, to move geometry between packages where FBX or glTF for some reason do not fit.
The output is a single .dae file: buildings extruded from OSM outlines by height or floor count, with materials colored by development type, and a flat base under them. The geometry is built in meters and centered on the selected area; there are no textures and no UV unwraps in the file — only colored materials.

Kes kasutab COLLADA-kaarte
Kuidas eksportida vormingusse COLLADA
Kuidas pärast eksporti avada
- SketchUp — File → Import → choose the COLLADA (.dae) type; in the import settings enable merging coplanar faces so the model comes out lighter.
- Blender — File → Import → Collada (.dae); materials carry over as simple colors and can be replaced with your own right away.
- Google Earth Pro — the model is shown through KMZ: put the .dae into an archive together with a KML file that ties the model to coordinates.
- Maya, 3ds Max and Unity — import DAE out of the box; in Unity it is enough to put the file into the project folder, it will be picked up as an asset.
- Scale check — the scene is in meters; if the model arrives the wrong size, set the units in the import dialog instead of scaling the objects by hand.
