camera->setPosition(Ogre::Vector3(0, 10, -10));
camera->setPosition(Ogre::Vector3(5, 0, 5));
camera->setPosition(Ogre::Vector3(0, 0, 0));These examples simply create a new 3D vector using Ogre::Vector3 and pass it to the Camera setPosition method to move the camera around in the 3D scene. The package library needed to use cpp ogre would be the Ogre package, which is a powerful and popular open-source 3D engine.
