BENTLEY_materials_planar_fill

[markschlosseratbentley]

Introduction

This PR describes an extension to glTF which meets the needs of Bentley Systems for customizing fill behavior for planar polygons.

Overview

Two- and three-dimensional planar polygons with filled interiors are fundamental elements in many 3D modeling and computer-aided design (CAD) environments. The BENTLEY_materials_planar_fill extension allows the behavior of a polygon's interior fill to be customized with the intent of being able to indicate a variety of meanings useful to CAD applications.

This specification describes a minimal extension sufficient to meet Bentley Systems' requirements, with some suggestions for how it might be broadened and/or generalized while retaining a focus on CAD visualization.

This is looking great to me. Do you have an implementation or is that still in progress?

PR is up for review on iTwin.js: iTwin/itwinjs-core#8906

CesiumJS implementation is beginning.

@markschlosseratbentley Cool, then I'm okay with this being merged into vendor-extensions. I just wanted to ensure that we had at least tested the implementation at least once in a dog fooding exercise.

However, you need to update the copyright. See my other comment.

I went ahead and added the link to the iTwin.js PR as a known implementation.

Nice work!
