Gazebo capability of light effects simulation
Say I want to see how well the visual localization on a robot would do during the night or at darker places given different lights I attach to the robot. Would Gazebo be sufficient simulation tool for that? Would it be possible to simulate dark place, the robot light and the camera in a way, that the camera would get realistic pictures?
In general I think it depends on how realistic you need things to look. You certainly have some control over lighting conditions.
