I have an issue with the depth map generated by Cycles : the depth map seems to have (radial) distortion, while the default Blender renderer does not.
So I am looking for information on the internal camera model used by the Cycles engine, or a way to retrieve/compute correct camera intrinsic parameters ? I guess the lens has distortion, but I could not find parameters or even code running this in Cycles.
I am posting here as it is more an internal code related issue than usage / UI / UX question.
I posted a more detailed question on the StackExchange : https://blender.stackexchange.com/questions/130970/cycles-generates-distorted-depth
