Linear rendering and HDR #380

Closed Try closed 1 year ago

Try commented 1 year ago

Linear color system is move correct in terms of math/rendering, so it would make sense to use it. Stuff like water/sky/dof heavily depends on it.

I've made a prototype in a branch: 08323f1361ad633da92e1a81ece3a7d18cc65442. Works well for penal colony and evenings and horrible for day-time and indoor scenes.

Also found a few bugs while on it - probably should fix them first.

Some screens for inspiration:

current main issue: bright day look: изображение

Left - gamma renderer, with fog ad-hook Right - linear+ Jodie Reinhard, additive fog

Sky is almost same, objects are close to sage (except pfx, not in screenshoot), foggy object - big problem

Inverse tonemapping for base-pass. Slightly better: изображение

Doesn't make much sense from physical point, but it's working very well from content point of view, since I need tone-mapped image looks similar original game
