How to create an ellipsoid
I would like to create an ellipsoid in Gazebo (and use it as static, and only visual, no collision). Reason for that is that I want to show an object and the minimum-volume ellipsoid enclosing the object. I have the algorithm to calculate the ellipsoid, but I don't know how to spawn it in Gazebo (no problem for a sphere, but I can't find any ellipsoid model). Is there any way to do so ? I'm using Gazebo7 and ROS Kinetic.
