贝塞尔点和控制点的简单区分
The Bezier interpolation factors indicate where the Bezier curve section starts and ends, and the Bezier point count indicates how detailed (or smooth) the curve should be. A Bezier point count of 1 technically disables the Bezier curve interpolation mechanism, but for simplicity, the control point is then referred to as a Bezier point .
Bezier point count代表贝塞尔曲线可以有多么细致（detailed ）
贝塞尔点数为1在技术上禁用贝塞尔曲线插值机制，但为简单起见，这时控制点被称为贝塞尔点。
