This class contains the description of a cubic Bézier curve and some associated methods.

Element Description

m_cData0 Changed in Version 2021.1

[MKI_POINTDATA] Start-point of the cubic Bézier curve.

m_cData1 Changed in Version 2021.1

[MKI_POINTDATA] First pivot point of the cubic Bézier curve.

m_cData2 Changed in Version 2021.1

[MKI_POINTDATA] Second pivot point of the cubic Bézier curve.

m_cData3 Changed in Version 2021.1

[MKI_POINTDATA] End-point of the cubic Bézier curve.

m_dT1

m_dT2

[double] Relative positions of the start-point and end-point of the Bézier curve relative to another Bézier curve. Unless this Bézier curve was created by splitting another curve, these values should be set to (0.0, 1.0).
