• The radar plugin shows the current viewing cone / area.
• It can be used on a floor map image to show the current viewing direction and field of view on it. Use the parent attribute to align in on a map image. Additionally it would be possible to mask out the radar to a specific area by applying an alpha mask image with the plugin mask attribute.
• The pano viewing direction can be changed by dragging the radar cone with the mouse. (Can be disabled by setting enabled="false".)
• The position and size of it can by adjusted with the standard plugin attributes.
• See the Radar Heading topic for instruction about how to setup the radar/pano heading.

Radar Aligment / Pano Heading

The heading the defines the orienation of the pano. It must be defined for each pano to align the radar to the map correctly.

The radar plugin includes a Radar Heading Edit Mode that helps finding the heading for the pano.

Here a how to for using the Edit Mode to find out the heading:

1. Enable the Edit Mode of the radar plugin by setting the editmode attribute to true:

   <plugin name="radar"
           url="radar.swf"
           ...
           heading="0"
           editmode="true"
           />

2. Right-click the radar and select "Radar Plugin - Edit Heading":
   
3. Now you can drag the radar to adjust the heading, find the heading where the pano view and the radar are showing the same view. There will be a red crosshair in the pano and a red line in the radar for helping finding the same point. The current heading and addtional information about the current xml or scene will be shown on the screen:
   
4. When done end the edit mode by right-click the radar again: The heading value will be copied into the system clipboard.
