9738	LookSee shows point cloud with wrong unidirectional lighting	goddard@…	Tom Goddard	"{{{
The following bug report has been submitted:
Platform:        macOS-13.5.2-x86_64-i386-64bit
ChimeraX Version: 1.7.dev202308222255 (2023-08-22 22:55:59 UTC)
Description
Point cloud written in GLTF format is shown in LookSee Quest VR app with normals all in same direction (along z I guess).  In BabylonJS sandbox it displays correctly without directional lighting.  The file does not contain normals.  The GLTF 2.0 spec says in section 3.9.7 ""Points or Lines with no NORMAL attribute SHOULD be rendered without lighting and instead use the sum of the base color value (as defined above, multiplied by COLOR_0 when present) and the emissive value.""

So this seems to be a bug in the GLTFast library used by LookSee.  Possibly newer GLTFast versions fix it.

I attached a file demonstrating the problem.
