Hello everyone,
I encountered a problem that seems to stem from stenciling osgText::Text -
if I do this, the Text will not be drawn at all.
Here more details of how my setup works:
I am writing a GUI system that uses stencils to limit the drawing area for
components stacked in another component (just like in any desktop GUI -
brings huge advantages for implementing scrollable lists etc):
1. Parent component increments the stencil buffer for its child area by
drawing a rectangle with osg::Geometry
It is added to the parent's osg::Group
2. Every child activates stencil testing, for the current stencil value
3. All children add their osg::Geodes/osg::Groups to the parent
component's osg::Group
4. Parent decrements the stencil buffer for the child area by drawing the
same rectangle
It is added to the parent's osg::Group
It (recursively) works fine for the osg::Geometry objects I draw, they get
cut off outside the allowed area.
But now I added osgText::Text, and it does not work at all - no text is
drawn, not even the bounding boxes or the alignment pointer thing that can
be additionally drawn!
If I disable the stencil testing (Point 2) for the text component, it
draws just fine, but of course potentially outside the parent area.
Do you have any idea what the reason for this behaviour could be? I can
create a code example that reproduces the problem if that would help.
Thanks in advance,
Christian
