Are my .b3dm files normal?

[djaw...@gmail.com]

hi there.

My wish is to build a 3d-building in the city.

There was a problem using cesium-3dtile..

Please see if my .b3dm file is normal.

Deformed in the following order :

.3ds (use blender)-> .obj (cesium : obj2gltf) -> .glb (cesium:3d-tiles-tools-master)-> .b3dm

If the file is normal, where is the coordinates setting ?

.3ds file have coordinates(Coordinate system:TM) I can convert it into wgs84 and ECEF.

Thank you for reading.

You'll want to convert it to ECEF. The b3dm's themselves are expected to be ECEF, no coordinate information. However you may define WGS84 lat/long rectangles for the bounding volumes in the tileset.json file.

thanks Sean

Are you saying that If I set the bounding volumes, I can make 3DTiles with that file?
Additional questions.
can i set coordinate(WGS84) to tileset.json file? I thought I was only a ECEF.

The b3dm file will need to be updated to ECEF. The tileset.json however can use WGS84 lat/long coordinates if you decide to use the "region" bounding volume type. Otherwise the "sphere" and "box" types are ECEF.

안녕하세요
부산에서 작업중인 오유상이라고합니다.
cesium 사용 관련해서 도움 구하고자합니다
b3dm파일에 ecef 형식의 좌표가 꼭 들어가야한다는 뜻인가요??
