詳細描述

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.

acceleration : float

Holds the current acceleration of the camera controller.

訪問函數：

float	acceleration () const
void	setAcceleration (float acceleration )

通知程序信號：

void	accelerationChanged (float acceleration )

camera : Qt3DRender::QCamera *

Holds the currently controlled camera.

訪問函數：

Qt3DRender::QCamera *	camera () const
void	setCamera (Qt3DRender::QCamera * camera )

通知程序信號：

void	cameraChanged ()

deceleration : float

Holds the current deceleration of the camera controller.

訪問函數：

float	deceleration () const
void	setDeceleration (float deceleration )

通知程序信號：

void	decelerationChanged (float deceleration )

linearSpeed : float

Holds the current linear speed of the camera controller. Linear speed determines the movement speed of the camera.

默認為 10.0 .

訪問函數：

float	linearSpeed () const
void	setLinearSpeed (float linearSpeed )

通知程序信號：

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.

默認為 180.0 .

訪問函數：

float	lookSpeed () const
void	setLookSpeed (float lookSpeed )

通知程序信號：

void	lookSpeedChanged ()

[protected] QAbstractCameraController:: QAbstractCameraController ( Qt3DCore::QNode * parent = nullptr)

Default constructs an instance of QAbstractCameraController.

[虛擬] QAbstractCameraController:: ~QAbstractCameraController ()

Destroys the instance of QAbstractCameraController. The destructor is virtual.

[protected] Qt3DInput::QKeyboardDevice *QAbstractCameraController:: keyboardDevice () const

Provides access to the keyboard device.

[protected] Qt3DInput::QMouseDevice *QAbstractCameraController:: mouseDevice () const

Provides access to the mouse device.
