详细描述

QFirstPersonCameraController class allows controlling the scene camera from the first person perspective.

The controls are:

Input	动作
Left mouse button	While the left mouse button is pressed, mouse movement along x-axis pans the camera and movement along y-axis tilts it.
Mouse scroll wheel	Zooms the camera in and out without changing the view center.
Shift key	Turns the fine motion control active while pressed. Makes mouse pan and tilt less sensitive.
方向键	Move the camera horizontally relative to camera viewport.
Page up and page down keys	Move the camera vertically relative to camera viewport.

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.

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.
