Hi,
I am trying to create a scene for a CAD-type app where I have objects that
should be a constant screen size as I zoom in and out, but when I cross a
certain zoom threshold it should change to a different size (for example half
its original size). I tried to implement this using a combination of
AutoTransform and LOD nodes. Here is a sample graph of two objects:
AutoTransform AutoTransform
\ /
LOD
/ \
MatrixTransform MatrixTransform
\ /
Geode
The problem I have is that when I have the AutoTransforms set to
autoScaleToScreen=true, then the level of detail does not change when it
should. It always stays at whatever level it started at regardless of how much
I move the camera in or out. If I set autoScaleToScreen to false, then the LOD
behaves as I expect (meaning it changes when I move the camera from one range
to another).
What might be causing this to happen? Is there another way to get the effect I
want?
...
Thank you!
Cheers,
Michael
