Summary

Function: rotation llEuler2Rot( vector v );

Returns a rotation representation of the "Wikipedia logo"Euler Angles v.

• vector v Angle

Specification

The Euler angle vector (in radians) is converted to a rotation by doing the rotations around the 3 axes in Z, Y, X order. So llEuler2Rot(<1.0, 2.0, 3.0> * DEG_TO_RAD) generates a rotation by first rotating 3 degrees around the global Z axis, then rotating the result around the global Y axis, and finally rotating that 1 degree around the global X axis.

Examples

default
{
    state_entry()
    {
        vector input = <73.0, -63.0, 20.0> * DEG_TO_RAD;
        rotation rot = llEuler2Rot(input);
        llSay(0,"The Euler2Rot of "+(string)input+" is: "+(string)rot );
    }
}

Notes

v/=2;
rotation k = <0.0, 0.0, llSin(v.z), llCos(v.z)> * <0.0, llSin(v.y), 0.0, llCos(v.y)> * <llSin(v.x), 0.0, 0.0, llCos(v.x)>;
