I would like to use projector on my project, for project a line to be used by a structured light algorithm.
However I realized that the lines are projected also behind the objects, when objects were supposed to block the projection.
I looked to the current issues and haven't see any issue directly related to it. I was wondering if this is related to: https://bitbucket.org/osrf/gazebo/issues/2083/point-and-spot-lights-dont-cast-shadows or https://bitbucket.org/ignitionrobotics/ign-rendering/issues/32/ogre1x-point-and-spot-lights-dont-cast
If so, is there any current alternative to it?
I'm running on Ubuntu 16.04 , Gazebo 9.8 and ign-rendering 0.29.1
