The Outputs panel displays the current studio camera orientation, position, zoom and focus as returned
from the free-d processor unit. Note that when LOMWIN is running with a receive-only data connection
to the Free-d processor unit, only the Outputs panel will display data.
Pan: The angle in degrees between the Y-axis and the projection of the studio camera's optical axis onto
the horizontal (XY) plane. A positive value indicates a pan to the right (i.e. the camera rotates clockwise
when viewed from above).
Tilt: The angle in degrees between the studio camera's optical axis and the horizontal (XY) plane. A
positive value indicates an upwards tilt. If both pan and tilt are zero the camera is looking in the direction
of the positive Y axis.
Roll: The angle of rotation in degrees of the studio camera about its optical axis. A positive value indicates
a clockwise roll, when viewed from behind the camera.
X-position: The horizontal displacement in millimetres of the camera from its reference position in the
direction of the X-axis.
Y-position: The horizontal displacement in millimetres of the camera from its reference position in the
direction of the Y-axis.
Height: The vertical displacement in millimetres of the camera from its reference position. A positive
value indicates an upwards displacement.
Zoom: A hexadecimal value related to the rotation of the zoom ring. It is the responsibility of the virtual
set system to convert this value to that required to control the rendering of the virtual background,
knowing the type of lens in use.
Focus: A hexadecimal value related to the rotation of the focus ring. It is the responsibility of the virtual
set system to convert this value to that required to control the rendering of the virtual background,
knowing the type of lens in use.
GPI: 16-bit hexadecimal value sent from the free-d camera. The first two digits are a general purpose 8bit
value corresponding to inputs fed to the camera's auxiliary connector; these are ignored by the free-d
system and can be used to carry any (slowly changing) data from the camera to the virtual set system. The
last two digits correspond to switch settings within the free-d camera (the fourth digit indicates the
approximate shutter speed as follows: 0 = 1/10000 sec, 1 = 1/4000 sec, 2 = 1/2000 sec).
