How to obtain Bayer RAW image for a scene

[Aleksandar Babic]

Hi,

Is there a way to output scene rendering as Bayer RAW image (e.g following BGGR pattern)?

Many thanks

Aleksandar

There is no built-in support for that. You would need to modify the Film implementation so that instead of storing XYZ at each pixel it instead stored four floats for BGGR. Then, in AddSample(), you could use the fractional components of the pFilm position to determine which Bayer pixel the sample landed in and then store just the corresponding R/G/B component there. (And then you'd need to write that out in whatever format was useful to you...)

Thanks,

Matt
