Google 3D Tiles feedback

[akre54]

Hi all -

Congratulations on the Google 3D Tiles launch! Looking great so far.

I’m using it in a demo project and so far it’s working great but but running into a couple issues:

• White flashes as gltf models pop in - is there a way to synchronize the camera or defer updating?

• Sometimes low-res textures get loaded in when zooming back out, and it “pops” in, which is distracting. Is it reloading the texture due to cache eviction, or is something else going on?
• Texture “tearing” / seams not aligning between neighboring tiles with different LOD levels

• At 0 pitch the ground is invisible. At anything else (1, e.g.) it’s fine. Seems to be a culling issue?

• High zoom levels seem to have a “jittering” / bumpiness (see the zoomed in airport video), like a stair step function, which seems to me to it has to do with 32 vs 64 bit floats maybe

Any ideas, or things to try before I open an Issue? Thanks!
