详细描述

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.

特性文档编制

acceleration : float

Holds the current acceleration of the camera controller.

访问函数：

float	acceleration () const
void	setAcceleration (float acceleration )

通知程序信号：

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 )

通知程序信号：

void	cameraChanged ()

deceleration : float

Holds the current deceleration of the camera controller.

访问函数：

float	deceleration () const
void	setDeceleration (float deceleration )

通知程序信号：

void	decelerationChanged (float deceleration )

linearSpeed : float

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

默认为 10.0 .

访问函数：

float	linearSpeed () const
void	setLinearSpeed (float linearSpeed )

通知程序信号：

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.

默认为 180.0 .

访问函数：

float	lookSpeed () const
void	setLookSpeed (float lookSpeed )

通知程序信号：

void	lookSpeedChanged ()
