{{函数详情
|函数名=Function: rotation llAxes2Rot( vector fwd, vector left, vector up );

|参数=返回由3个坐标轴定义的旋转
|返回值=•矢量fwd
•矢量左
•矢量向上
这三个向量必须是相互正交的单位向量。

|示例=
<pre>
default
{
    state_entry()
    {
        vector i = < 1.0, 0.0, 0.0>;
        vector j = < 0.0, 1.0, 0.0>;
        vector k = < 0.0, 0.0, 1.0>;
 
        rotation rot = llAxes2Rot( j, -i, k );
 
        llSay(0, (string) (llRot2Euler(rot) * RAD_TO_DEG) );
    }
}
This script displays:

  Object: <-0.00000, 0.00000, 90.00000>
which shows that (j, -i, k) is obtained by rotating (i, j, k) 90 degrees around z direction.

Technically, only the first two vectors are needed to define this rotation, which can be done by calling any of these:

llAxes2Rot(fwd, left, fwd % left);
llAxes2Rot(left % up, left, up);
llAxes2Rot(fwd, up % fwd, up);
