The AlmostEqual method in the Rotation struct is used to determine if two rotations are approximately equal within a specified tolerance. This method is useful when you need to compare rotations but want to allow for minor differences that may arise due to floating-point precision errors.
To use the AlmostEqual method, you need to provide a reference to a Rotation object and a float value representing the tolerance level. The method will return true if the current rotation is approximately equal to the provided rotation within the specified delta, otherwise it returns false.
// Example usage of the AlmostEqual method Rotation rotation1 = Rotation.FromAxis(Vector3.Up, 45); Rotation rotation2 = Rotation.FromAxis(Vector3.Up, 45.1f); float tolerance = 0.2f; bool areAlmostEqual = rotation1.AlmostEqual(ref rotation2, tolerance); // areAlmostEqual will be true if the difference between rotation1 and rotation2 is less than or equal to 0.2 degrees.
