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()

Member Function Documentation
