When I had a closer look at my models I noticed that there is a parallax effect visible when I rotate the camera (see images: Image 1: how it should be (model exactly at the desired position), Image 2: tilted view on the same model, as you can see, the model is now “over” the grey path (the path is part of the background image and not a model itself) on the ground near the river, Image 3: same effect on the other side, now the model is shifted away from the grey path).
I had this problem before when I used a terrain provider, but now it is just a “flat” earth without any terrain associated. I thought when there is no height information included then this effect should not happen. The models were not produced with the WGS84 Ellipsoid in the “background” in CityEngine, could that be a problem? Is there any height information somewhere stored in the gltf model itself (there are no specific z values associated in the DAE file)? The DAE and the glTF file of this building are attached.
(I draw the models with "Transforms.eastNorthUpToFixeFrame(origin); but it happens also with Transforms.headingPitchRollToFixedFrame(origin, heading, pitch, roll), the latter three are set to 0.)
Thanks for any tips
