IDP.Math.KBoundedCurve3d.getApproximatePointsInfoByNormalTol() method

对当前有界曲线进行离散，保证相邻两点之间的法向夹角小于给定值，相邻两点之间的曲线段和弦之间的近似三角形面积小于给定值。

Discretize bounded curve to points with specified normal tolerance and area tolerance.

Signature:

getApproximatePointsInfoByNormalTol(normTol?: number, areaTol?: number): {
        points: KPoint3d[];
        params: number[];
    };

Parameters

Parameter	Type	Description
normTol	number	(Optional) 相邻两点之间法向夹角误差（angle < acos(1-normTol)）。 如果没有输入法向误差值或者输入值过小（<1.0e-6）或者过大（>1.0 - 1.0e-6），则默认会采用0.01。 The normal tolerance between two adjacent points (angle < acos(1-normTol)). If normTol is not provided or the value is too small(<1.0e-6) or too big(>1.0 - 1.0e-6), then it will use default value 0.01.
areaTol	number	(Optional) 相邻两点之间的曲线段和弦之间的近似三角形面积。 如果没有输入面积值或者面积值过小（<1.0e-6）, 则不使用面积误差作为判断条件。 The approximate area between the bounded curve and the chord of two adjacent points. If the area is not provided or the vlaue is too small(<1.0e-6), then the check condition will not use the area.

Returns:

{ points: KPoint3d[]; params: number[]; }
