Detailed Description

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

The controls are:

InputAction
Left mouse buttonWhile the left mouse button is pressed, mouse movement along x-axis pans the camera and movement along y-axis tilts it.
Mouse scroll wheelZooms the camera in and out without changing the view center.
Shift keyTurns the fine motion control active while pressed. Makes mouse pan and tilt less sensitive.
Arrow keysMove the camera horizontally relative to camera viewport.
Page up and page down keysMove the camera vertically relative to camera viewport.

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.

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.

Access functions:

float lookSpeed() const
void setLookSpeed(float lookSpeed)

Notifier signal:

void lookSpeedChanged()

Member Function Documentation

QFirstPersonCameraController::QFirstPersonCameraController(Qt3DCore::QNode *parent = nullptr)
