Is gc the coordinate of target or calulated vector #11

Closed LazyKai closed 3 years ago

gc_normalized = gc - face_center # gaze vector I am not sure whether gc is the coordinate of target based on camera coordinate system or already calculated based on head coordinate system? And why doing this step? please explain this, thanks!

Hi,

gc is the gaze point in the camera coordinate system. In other words. gc is the gaze point on the screen, and is converted to the camera coordinate system. gc_normalized is the real gaze vector.
