Hi,

I want to create a 3D tileset of trees of an city. Whenever i searched for similar process in Cesium and FME related communities, i noticed that people mostly used "instanced 3D tiles" (Cesium3Dtiles with i3dm file format) to represent the objects sharing same geometries (like trees, billboards, citylights etc.). Actually FME have very useful transformers to calculate coordinates of center points of these objects, but it doesn't support i3dm tilesets.

Do you know any option or suggestions about creating i3dm tilesets using only FME or with help of a 3rd party solution?

Hi @muratkendir,

I'm sorry, but FME's Cesium 3D Tile writer only creates b3dm files at present.

However, the addition of i3dm writing would be a great idea, especially since FME already supports instanced geometries internally. It would be best to share this with the rest of the FME community so that they can vote and contribute to it. Would you be willing to add this to the Ideas exchange?
