Summary

Function: rotation llEuler2Rot( vector v );

Returns a rotation representation of Euler Angles v.

• vector v

Specification

The Euler angle vector is converted to a rotation by doing the rotations around the 3 axes in Z, Y, X order. So llRot2Euler(<1.0, 2.0, 3.0> * DEG_TO_RAD) generates a rotation by taking the zero rotation, a vector pointing along the X axis, first rotating it 3 degrees around the global Z axis, then rotating the resulting vector 2 degrees around the global Y axis, and finally rotating that 1 degree around the global X axis.

Examples

<lsl> default {

   state_entry()
   {
       vector input = <73.0, -63.0, 20.0> * DEG_TO_RAD;//not advised to make your own quaternion
       rotation rot = llEuler2Rot(input);
       llSay(0,"The Euler2Rot of "+(string)input+" is: "+(string)rot );
   }

}

</lsl>

Notes

<lsl>v/=2; rotation k = <0,0,llSin(v.z),llCos(v.z)> * <0,llSin(v.y),0,llCos(v.y)> * <llSin(v.x),0,0,llCos(v.x)>;</lsl>
