llEuler2Rot

rotation llEuler2Rot(vector Vector)

Returns the rotation representation of the Euler angles.

Returns the rotation represented by the Euler Angle.

Parameters
Vector (vector)
Technical Details
  • Return Type: rotation
  • Energy: 10

The Euler angle vector (in radians) is converted to a rotation by performing rotations around the 3 axes in Z, Y, X order. For example, 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 result 1 degree around the global X axis.

Examples

Section titled “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 );
    }
}

Implementation Details

Section titled “Implementation Details”

The conversion can be expressed mathematically as:

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)>;
