Does anyone know a way to load a HDR image chunk by chunk? I am trying to parallelize a Reinhard Operator algorithm and I have high R/W times. I am trying to reduce that by loading chunks of image at a time, but I can't get my head around it. Is it possible with STB library, or does anyone know another way?
Thanks!
I tried loading the full image at first and then split it, but it does not help much, as the initial reading takes long.
