- Rolling Shutter Correction in 3DE4
This document describes the underlying mathematics for 3DE4's rolling shutter compensation.
It is addressed to developers who want to build a lens shader for taking into account 3DE4's rolling shutter compensation factor during the rendering process, thus producing CGI content which matches the tracked footage's rolling shutter distortion.
In addition, the information found in this tech. doc can be used to develop plugins for standard compositing tools, which allow to remove rolling shutter distortion from live action footage or apply the same to CGI.
