Head Up Display
The HUD allows the user to see live control data, and the status of the media player, overlaid on the projected output.
The HUD is always displayed on top of the output layer, and does not have any colour effects applied to it. It does get keystoned .
It displays a border round the entire screen so that you can see the full extent of the projection area even when the output has
been modified, distorted, or turned off. This allows a projector to be aligned even without media. Unless you are projecting on
a very irregular surface, you should always be able to see the HUD no matter what configuration has been applied to the other
layers.
The DMX channel that controls the HUD allows it to be positioned left, centre or right of screen; and selects the layer whose
DMX data is shown.
Thumbnails of each layer are shown, whether or not they are visible in the output. This allows the user to see all the content that
is making up the output, not just what is visible.
Changing DMX parameters are highlighted, as are illegal/erroneous values. The raw DMX channel data is shown, along with the
converted value (e.g. angle is shown as a 16 bit value, and also as the resulting angle in degrees). This helps you to understand
the effect that the parameters have on the output.
The HUD can also display a grid to help with projector alignment and keystoning . Like the normal HUD display, the grid is not
subject to output intensity or colour control, and appears whether or not any media is displayed.
