Function: vector llRot2Axis( rotation rot );


0.0	Forced Delay
10.0	Energy

Returns a vector the rotation axis represented by rot

• rotation

Use in conjunction with llRot2Angle.
To undo use llAxisAngle2Rot or llAxes2Rot.

vector llRot2Axis(rotation a) {
    if(a.s < 0)
        return -llVecNorm(<a.x, a.y, a.z>);
    return llVecNorm(<a.x, a.y, a.z>)
}

vector llRot2Axis(rotation a) {
    return llVecNorm(<a.x, a.y, a.z>) * (1 | -(a.s < 0));
}
