function
Function syntax
rotation llAxisAngle2Rot(vector axis,// Axis vector to rotate around.float angle// Angle to rotate, in radians.
);- Returns
rotation- Energy
- 10
axis need not be normalized, only the direction is important.
angle need to be between the value 0<angle<PI (higher values than PI lead to 2*PI-angle)
, because a rotation is not really a rotation (it is more of a rigid motion/mirroring)
,the final destination is the rotation.
(in other words: it doesn’t matter wether you rotate left by 90 degrees or right by 270 degrees it will return the same rotation)
Returns a rotation that is a generated angle about axis

Section titled “Examples”Example 1
default{ state_entry() { vector axis = <0.0, 0.0, 1.0>; float angle = 90.0 * DEG_TO_RAD; rotation rot = llAxisAngle2Rot(axis, angle); vector euler = llRot2Euler(rot) * RAD_TO_DEG;
llOwnerSay((string) euler); //Says <0.0, 0.0, 90.0> since it is rotating 90 degrees on the Z axis caused by the 1.0 placed in the Z vector spot. }}See also
