Detailed Description
The QAbstractCameraController class provides basic functionality for camera controllers.
QAbstractCameraController sets up and handles input from keyboard, mouse, and other devices. QAbstractCameraController is an abstract class and cannot itself be instantiated. It provides a standard interface for camera controllers.
Derived classes need only implement the frameActionTriggered() method to move the camera.
Property Documentation
acceleration : float
Holds the current acceleration of the camera controller.
Access functions:
float | acceleration() const |
void | setAcceleration(float acceleration) |
Notifier signal:
void | accelerationChanged(float acceleration) |
camera : Qt3DRender::QCamera*
Holds the currently controlled camera.
Access functions:
Qt3DRender::QCamera * | camera() const |
void | setCamera(Qt3DRender::QCamera *camera) |
Notifier signal:
void | cameraChanged() |
deceleration : float
Holds the current deceleration of the camera controller.
Access functions:
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.
The default is 10.0
.
Access functions:
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.
The default is 180.0
.
Access functions:
float | lookSpeed() const |
void | setLookSpeed(float lookSpeed) |
Notifier signal:
void | lookSpeedChanged() |
