IDP.Math.KGeomLib.createRotateMatrix4() method
创建围绕轴旋转的变换矩阵。 旋转轴由一点和一向量定义,旋转角度由弧度值给出。
Create an transform matrix that does rotation about an axis. The axis is defined by a point and a vector. The angle is given in radians.
Signature:
createRotateMatrix4(angle: number, a: KVector3d, center: KPoint3d): KMatrix4;
Links: createRotateMatrix4(angle: number, a: KVector3d, center: KPoint3d): KMatrix4;
