Weird Warped geometry on google 3D Data

[tbenazzi]

Hello @vvoovv , we recently detected some very weird warped geometry on downloaded dataset.

The data doesn't appear like that in google. Do you know where it could come from ?

It looks like a big wave of displacement... first time we detect it.

Hi @tbenazzi

Could you please point to this place on map?

It's in Monaco !

I can explain it by a single floating point precision used by Blender.

Blender's glTF import heavily relies on Blender's internal data structure like Vector and Matrix. There is a precision loss after converting from Python data structures (double precision) to Blender data structures (single precision).
