Gamma correction and tonemapping
straaljager opened this issue · comments
Required to obtain realistic looking lighting.
Blender pioneered a tonemapping filter called "Filmic", which adds a lot of realism: https://www.blenderguru.com/tutorials/secret-ingredient-photorealism
ospray might already have someting to fit this need: https://github.com/ospray/ospray/blob/master/ospray/fb/ToneMapperPixelOp.h
Great, looks like it has an implementation of the filmic tonemapper.
Gamma correction and tone mapping are now implemented as part of Brayns 3.0.0 and available on master branch.
