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 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.
Caveats
Examples
<lsl>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 );
}
}</lsl>
Notes
<lsl>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)>;</lsl>
