Satellites not rendered on Chrome for Mac

[ajmas]

I am using Chrome 63.0.3239.40 on macOS 10.13.1 and the orbital object indicators aren't being rendered (the blue, red and grey dots). They work fine on iOS Safari and the Safari in macOS.

Hi, could you post screenshots of http://webglreport.com/?v=1 for both Chrome and Safari?

[ajmas]

Added. Also, http://webglreport.com/?v=2, just in case

webgl - chrome - webgl 1

webgl - chrome - webgl 2

webgl - safari - webgl 1

webgl - safari - webgl 2

Additionally, on a fork I have (https://ajmas.github.io/ThingsInSpace/), I noticed the following in the console:

Both browsers seem to be reporting the exact same WebGL capabilities, which is interesting. The dots are drawn using point sprites, for which support doesn't seem to be guaranteed.

[jeyoder]

The INVALID_ENUM error is intentional, it's thrown on a line of code used to trick some older OpenGL implementations to enable point sprites.

[ajmas]

Just looking for some examples of 'point sprites' that work in both browsers, I came across: https://codepen.io/AzazelN28/pen/zvXZQw I haven't dug into your code yet to see how the logic compares

This is still broken on Chrome for Mac.

in 2020 still broken on Chrome for Mac.

This is working in the latest version of Chrome (116.0.5845.187), on macOS. You can see it live here:

I have also tested this as working in Safari on an Intel based Mac, on both macOS 13 and and macOS 14.
