Description

Blender and other programs now support the glTF (GL transmission format): https://www.khronos.org/gltf/

There's a lot - but it's a JSON format that includes support for simple meshes, animations, etc. https://github.com/KhronosGroup/glTF-Tutorials/blob/master/gltfTutorial/README.md https://github.com/KhronosGroup/glTF-Tutorials/blob/master/gltfTutorial/gltfTutorial_008_SimpleMeshes.md

The ChimeraX program includes support: http://rbvi.ucsf.edu/chimerax/docs/user/commands/save.html#formats

Contributor guide

Research direction
Investigate the existing file export architecture in the Avogadro libraries, particularly how other formats are written. Familiarize yourself with the glTF and .glb specifications and their tutorial links. Propose a design for exporting molecular structures as glTF, starting with basic meshes and material properties.
