\qmlproperty enumeration ScaleAffector3D::ScalingType
Defines the scaling type of the affector.
\value ScaleAffector3D.Linear The scale is calculated using the easing curve to interpolate between minimum and maximum scale size between duration milliseconds and then continues from the minimum size. \value ScaleAffector3D.SewSaw The scale is calculated using the easing curve to interpolate between minimum and maximum scale size between duration milliseconds on a rising edge then continues from maximum to minimum on a falling edge. \value ScaleAffector3D.SineWave The scale follows the sine wave. Easing curve is not used. \value ScaleAffector3D.AbsSineWave The scale follows the sine wave except negative values are inverted. Easing curve is not used. \value ScaleAffector3D.Step The scale stays at minimum size until half of the duration milliseconds have passed then steps directly to the maximum size. Easing curve is not used. \value ScaleAffector3D.SmoothStep The scale smootly transitions from minimum to maximum size. Easing curve is not used.
\qmlproperty ScalingType ScaleAffector3D::type
This property holds the scaling type of the affector. The default value is Linear
