Discretize the Arc to points with specified angle.
Signature:
getApproximatePointsByAngle(angleSpan?: number): KPoint3d[];
Links: getApproximatePointsByAngle(angleSpan?: number): KPoint3d[];
Parameters
Parameter | Type | Description |
---|---|---|
angleSpan | number | (Optional) 圆心角(以弧度为单位)。 如果没有输入角度值或者输入值过小(<1.0e-6),则默认使用PI/60个弧度。 Central angle span in radians. If angleSpan is not provided or the value is too small(<1.0e-6), then it will use default value PI/60. |
Returns:
KPoint3d[]
离散点列。
The discretized points.
