Does 3DTile Support UTM Coordinate System?

Cesium for Unity
1

Hi Cesium team,

I’m currently working on a project using Cesium for Unity, and I would like to know if 3D Tiles natively support the UTM (Universal Transverse Mercator) coordinate system. If not, are there any recommendations or best practices for converting UTM data into a compatible format for use with Cesium in Unity?

Any insights or guidance would be greatly appreciated!

Thanks in advance.

3D Tiles does not natively support UTM or any other projected coordinate system. The idea is that 3D Tiles vertex positions can always be transformed into real-world, 3D coordinates with only an affine transformation matrix (typically translation, rotation, scale).

However, the tool that you’re using to create 3D Tiles may be help unproject your projected data before tiling. What sort of data are you starting with, and what tools are you using to process it?
