Refactor direct lighting #30

Closed codeonwort closed 2 years ago

codeonwort commented 2 years ago

Was gonna implement area lights but I had to make too many changes before even working on it. Merge now and let's work on area lights.

Main changes

Refactor direct lighting.
- Render light sources one by one. No loop to process all lights in one invocation.
- Delete deprecated phong shading from direct lighting.
- Remove bloom addition from direct lighting. Moved to bloom setup.
sceneColor no more stores '-positionVS.z' in the alpha channel.
UBO_PerFrame no more stores light info array.

Misc

Add World_LightRoom: Demo world to test area light.
Add non-smoothed cube geometry.
