hey shader people. how do you calculate the brightness of an rgb triplet in linear color space. does it use the same perceived brightness kernel or do you have to do it differently?

[aeva@mastodon.gamedev.place]

@eniko it depends on how you define brightness

[aeva@mastodon.gamedev.place]

@eniko depending on how robust you need this to be, it could be as simple as taking the "green" channel

@aeva atm im just using 0.299, 0.587, 0.114 kernel
