Detailed Description
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() |
