How to export a Gltf as Quad data?

[Edit:] fixed the referenced jsfiddle

Quads are problematic because there is no constraint on them being planar,

Agreed.

@manthrax

but for rendering, they introduce a lot of complexity with next to zero benefit.

I beg to differ:

A few years ago, we had a discussion here about the

Mapping-fidelity in quadrilateral/triangle rendering

Hi all, I’ve investigated a behaviour which seems peculiar to me, and might benefit from an improvement. A Jsfiddle is included in this topic. The Jsfiddle goes pretty much along the lines of this Demo (geometry / teapot), except for the fact, that I’m using a LatheGeometry instead of the teapot, and a very simple 4-vertex path. You can also modify the # of lathe segments via a UI element. That said: I’m starting with a decagon (latheSegments = 10) and am mapping the well known “uv_grid_opengl…

See this for a reminder:

I understand some of the reasons, why support for quad rendering has been removed from Three.js. But there are cases where mapping quality (and by extension: quality of reflections) would greatly benefit from rendering quads.
