WebOpen the view settings panel (the button) and set the Display space to the image which you want oriented. My images are aligned in FSLeyes, but other FSL tools complain about orientation! FSLeyes projects all of the overlays that you load into a common display coordinate system, regardless of their dimensions, orientation, or field of view. WebA bit late for this answer, but all you really need is to compute the angle between transform.forward of the camera and the vector to your object, which is derived by subtracting the transform.position (s). You can use Vector3.angle for that. If the resultant angle is less than half the field of view, than your object will be in the field of view. city gate mri marysville ohio
