float llAngleBetween(rotation r1, rotation r2)

Return the angle between two rotations.

The first rotation

The second rotation

Returns the angle between the two rotations.

• Given two rotations r1 and r2, there is a third rotation that transforms one into the other, given by r2/r1. The angle this function returns is the angle of that last rotation. Therefore, it is roughly equivalent to llRot2Angle(r2/r1).

llOwnerSay((string)(llAngleBetween(<0,0,1,0>, <0,1,0,0>)*RAD_TO_DEG)); // displays 180.000000

• llRotBetween Rotation between two vectors.
• llRot2Angle obtains the angle part of a rotation expressed as axis/angle.
• llRot2Axis obtains the axis part of a rotation expressed as axis/angle.
• rotation type and operations.
