Property Detail
|
readatomicassign |
Indicates whether the detector found the head y euler angle.
|
readatomicassign |
Indicates the rotation of the face about the vertical axis of the image.
Positive euler y is when the face is turned towards the right side of the image that is being processed.
|
readatomicassign |
Indicates whether the detector found the head z euler angle.
|
readatomicassign |
Indicates the rotation of the face about the axis pointing out of the image.
Positive euler z is a counter-clockwise rotation within the image plane.
|
