Radar Plugin radar.swf / radar.js Version 1.19-pr13

  • 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. By using maskchildren="true" on the parent element it's possible to draw the radar cone only with the parent layer.
  • The pano viewing direction can be changed by dragging the radar cone with the mouse (but could be disabled by adding enabled="false").
  • The position and size of it can by adjusted with the standard plugin attributes.


Usage Example:
<plugin name="radar"
        x="100" y="50"

Dynamically set the heading and x/y position:
set(plugin[radar].x, 203);
set(plugin[radar].y, 555);
set(plugin[radar].heading, 91.8);
