In a previous post I asked if 100,000 polygons is still the recommended size for USDZ Quick Look models on the web. (The answer is yes)

But I realize my polygons are 4-sided but are not planar, so they have to be broken down into 2 triangles when rendered.

Given that, should I shoot for 50,000 polygons (i.e., 100,000 triangles)?

Or does the 100,000 polygon statistic already assume polygons will be subdivided into triangles?

(The models are generated from digital terrain (GeoTIFF) data, not a 3D modeling tool)

Yes, I would suggest you shoot for 100k triangles, but it's always worth testing if you can go over the suggested limit.

Triangles are used internally to construct polygons and your polygons shouldn't go past 4 sides and if they do then you should try to break into down into a smaller polygon.
