[osg-users] Possible Bug in osg::AutoTransform

[Cysneros, Nelson SPAWAR]

I think their might be a bug with osg::AutoTransform object.  I'm using
the setAutoScaleToScreen() function and it works as expected (the
transform object stays the same size on the screen no matter how much
you zoom in or out), but you don't have any control over the initial
size of the object.  I would like to set the initial size of the
transform with the setScale() function, but once you use the
setAutoScaleToScreen() function, the setScale() function does not have
any affect on the object.
 
I was able to duplicate the problem with the osgautotransform.cpp
example. (File is attached)
 
            osg::AutoTransform* at = new osg::AutoTransform;
            at->setPosition(pos);
   
            at->setScale(100000);  //vec3 argument does not work either
            at->setAutoScaleToScreen(true); //Scale does not work with
this on
 
 
The above code has no affect on the scaling unless  you set
setAutoScaleToScreen to false.
 
 
 
Thank you
