Chapter 340: CubicBezierCurve3

Core Idea

A curve representing a 3D Cubic Bezier curve.

Key Concepts

• isCubicBezierCurve3 : boolean (readonly): This flag can be used for type testing.
• v0 : Vector3: The start point.
• v1 : Vector3: The first control point.
• v2 : Vector3: The second control point.
• v3 : Vector3: The end point.
