KVector3d.angleTo() method
以特定方向来计算两向量的夹角，以弧度计。
Calculate the angle to other vector, with vecRef as reference.
Signature:
angleTo(other: KVector3d, vecRef: KVector3d): number;
Links: angleTo(other: KVector3d, vecRef: KVector3d): number;
Parameters
Parameter | Type | Description |
|---|---|---|
other | 要比较的向量。 The vector to compare this vector with. | |
vecRef | 该向量用来决定角度计算的时针方向。 the reference vec to determine the counter clockwise direction. |
Returns:
number
两向量的夹角，范围为[0, 2PI]。
The angle between the two vectors, the range is [0, 2PI).
