This video shows several functionality of V-REP, but the focus is on the vision sensor functionality: in V-REP a vision sensor is similar to a camera, but many parameters can be adjusted (resolution, what objects are seen, etc.) and filters can be applied: V-REP offers more than 30 built-in filter components that can be combined in any way and that allow processing a vision sensor's image, and extracting useful information (e.g. center of gravity of a color patch, orientation, etc.).
