详细描述
The QFirstPersonCameraController class allows controlling the scene camera from the first person perspective.
The controls are:
| Input | Action |
|---|---|
| Left mouse button | While the left mouse button is pressed, mouse movement along x-axis pans the camera and movement along y-axis tilts it. |
| Mouse scroll wheel | Zooms the camera in and out without changing the view center. |
| Shift key | Turns the fine motion control active while pressed. Makes mouse pan and tilt less sensitive. |
| Arrow keys | Move the camera horizontally relative to camera viewport. |
| Page up and page down keys | Move the camera vertically relative to camera viewport. |
属性
acceleration : float
Holds the current acceleration of the camera controller.
访问函数:
| float | acceleration() const |
| void | setAcceleration(float acceleration) |
Notifier signal:
| void | accelerationChanged(float acceleration) |
camera : Qt3DRender::QCamera *
Holds the currently controlled camera.
访问函数:
| Qt3DRender::QCamera * | camera() const |
| void | setCamera(Qt3DRender::QCamera *camera) |
Notifier signal:
| void | cameraChanged() |
deceleration : float
Holds the current deceleration of the camera controller.
访问函数:
| float | deceleration() const |
| void | setDeceleration(float deceleration) |
Notifier signal:
| void | decelerationChanged(float deceleration) |
linearSpeed : float
Holds the current linear speed of the camera controller. Linear speed determines the movement speed of the camera.
访问函数:
| float | linearSpeed() const |
| void | setLinearSpeed(float linearSpeed) |
Notifier signal:
| void | linearSpeedChanged() |
lookSpeed : float
Holds the current look speed of the camera controller. The look speed determines the turn rate of the camera pan and tilt.
访问函数:
| float | lookSpeed() const |
| void | setLookSpeed(float lookSpeed) |
Notifier signal:
| void | lookSpeedChanged() |
