"sdv_image_warp" is a command line tool shipped with 3DE4 Release 6 for applying or removing Lens distortion from single images. It is either applied directly to the footage, or it may be used to create ST maps compatible with Nuke's STMap nodes. This document shows how to use the tool in various situations. In addition, the results of automated tests are presented, which are intended to ensure that the tool remains free of bugs in the course of further development.
