Detailed Description

Implementation of an augmented reality viewer using Ogre3D 3rd party.

Thus to be enabled this class requires Ogre3D 3rd party installation. Installation instructions are provided here https://visp.inria.fr/3rd_ogre.

This class provides methods to show a 3D scene in a real world. To do that you will need to initialise it with the parameters of your camera, then each frame you will need to compute a pose for your camera and give it to the application. With that information and the image to be shown in background it will set up the 3D scene correspondingly.

Examples:

AROgre.cpp, AROgreBasic.cpp, HelloWorldOgre.cpp, HelloWorldOgreAdvanced.cpp, tutorial-ibvs-4pts-ogre-tracking.cpp, and tutorial-ibvs-4pts-ogre.cpp.
