#5144547 help on hdr rendering

Posted by esoufiane on 05 April 2014 - 06:23 AM

Isn't it just possible to write a compute shader that goes over all pixels and sum all of log luminances and put it in a float . then simply we can multiply this float value by 1/N either by cpu or gpu ?

 

This can be done by using Parallel Reduction algorithm:

Here is a useful article about software rasterization with an implementation of the half space algorithm.
