Hi<br><br>I have been trying to add a line widget to my view with one end fixed at the origin. Basically it is going to represent and incoming ray and is going to be used for getting the incident angle of the ray on which my filter will work.<br>
<br>I looked at the elevation filter and added the line as described there but the resulting line widget has both end freely movable. Also how can i make the panel to be updated with the angle of the line vector instead of the point coordinates?<br>
<br>thanks <br clear="all"><br>-- <br>Shailender Kanwar<br><br><br>
