[osg-users] Draw geometry that keeps its size in screen even with user manipulation (scaling, etc)

[Bruno Oliveira]

Thank you Tracje,

however I tried using that. My node has, for instance, 10 circles that
represent points and that are at a certain distance. I use autotransform on
the whole node of 10 circles with "setAutoScaleToScreen(true);" but what
happens is that when I zoom my scene, the distance between the circles does
not change.
Do I need to add an autotransform for each circle?
