詳細描述

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

The controls are:

輸入	動作
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.
方嚮鍵	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.

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.

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
