| \ingroup qt3d-extras-cameracontrollers |
| \brief The QFirstPersonCameraController class allows controlling the scene camera |
| from the first person perspective. |
| \inmodule Qt3DExtras |
| \since 5.7 |
| \inherits Qt3DCore::QEntity |
| |
| The controls are: |
| \table |
| \header |
| \li Input |
| \li Action |
| \row |
| \li Left mouse button |
| \li While the left mouse button is pressed, mouse movement along x-axis pans the camera and |
| movement along y-axis tilts it. |
| \row |
| \li Mouse scroll wheel |
| \li Zooms the camera in and out without changing the view center. |
| \row |
| \li Shift key |
| \li Turns the fine motion control active while pressed. Makes mouse pan and tilt less |
| sensitive. |
| \row |
| \li Arrow keys |
| \li Move the camera horizontally relative to camera viewport. |
| \row |
| \li Page up and page down keys |
| \li Move the camera vertically relative to camera viewport. |
| \row |
| \li Escape |
| \li Moves the camera so that entire scene is visible in the camera viewport. |
