Hi Glenn,
i tried that function but i didn't find it... it may be i am not using recent
osgEarth. I d like to get another way: i saw that CircleNode has setRadius()
and i can use this to draw more times. To resize the i d need to know some
ABSOLUTE NUMBER for example distance of projection of the camera to sea level.
Is it possibile getting this value?
Please help me.... I am getting crazy javascript:emoticon(':\'')
javascript:emoticon(':\'')
javascript:emoticon(':)')
