The function updateCameras() is called each time the DisplayCB function runs. Using the method SetLocalPosition from the Camera class we can move the camera in the world:

void updateCameras()
double angle = g_offset / 2 * M_PI;
double x = sin(angle) * 3.0 + 3.0;
double y = cos(angle) * 3.0;
for (ir::CameraPtr camera : g_cameras)
camera->SetLocalPosition(x, y, 0.0);
g_offset += 0.0005;
