## Method Documentation

void pan(real angle, vector3d axis)

Adjusts the camera pan about view center by angle in degrees on axis.

void pan(real angle)

Adjusts the pan angle of the camera by angle in degrees.

void panAboutViewCenter(real angle, vector3d axis)

Adjusts the camera pan about view center by angle in degrees on axis.

void panAboutViewCenter(real angle)

Adjusts the camera pan about view center by angle in degrees.

quaternion panRotation(real angle)

Returns the calculated pan rotation in relation to the angle in degrees taken in to adjust the camera's pan or left/right rotation on the Y axis.

void roll(real angle)

Adjusts the camera roll by angle in degrees.

void rollAboutViewCenter(real angle)

Adjusts the camera roll about view center by angle in degrees.

quaternion rollRotation(real angle)

Returns the calculated roll rotation in relation to the angle in degrees taken in to adjust the camera's roll or lean left/right rotation on the Z axis.

void rotate(quaternion q)

Rotates the camera with the use of a Quaternion in q.

void rotateAboutViewCenter(quaternion q)

Rotates the camera about the view center with the use of a Quaternion in q.

quaternion rotation(real angle, vector3d axis)

Returns the calculated rotation in relation to the angle in degrees and chosen axis taken in.

void tilt(real angle)

Adjusts the tilt angle of the camera by angle in degrees.

void tiltAboutViewCenter(real angle)

Adjusts the camera tilt about view center by angle in degrees.

quaternion tiltRotation(real angle)

Returns the calculated tilt rotation in relation to the angle in degrees taken in to adjust the camera's tilt or up/down rotation on the X axis.

void translate(vector3d vLocal, enumeration option)

Translates the camera's position and its view vector by vLocal in local coordinates. The option allows for toggling whether the view center should be translated.

- Camera.TranslateViewCenter
- Camera.DontTranslateViewCenter

See also Qt3DRender::QCamera::CameraTranslationOption.

void translateWorld(vector3d vWorld, enumeration option)

Translates the camera's position and its view vector by vWorld in world coordinates. The option allows for toggling whether the view center should be translated.

- Camera.TranslateViewCenter
- Camera.DontTranslateViewCenter
