Hi Vic,
Thank you! That appears to work! It allows me to open several windows at once,
though the program (and the windows that open) are not responsive for some
reason. Could be my fault, not sure.
How do I associate a osgViewer::Viewer with a osg::GraphicsContext so that it
renders inside of that specific window?
You set the graphics context on a camera.
In your case, if you always have only one view open at a time, you'll be
using an osgViewer::Viewer, which derives from osgViewer::View, which
has a camera (viewer->getCamera() will get it). You call
viewer->getCamera()->setGraphicsContext(gc) to use it.
If you had to have multiple views (which can each be in separate windows
or not) open and rendering at the same time, you'd want a
CompositeViewer, which has a list of osgViewer::Views, each of which has
a camera, which can use the same or different graphics contexts.
Another thing... simplified description of how I have set it up: I'm using a
game loop that checks a global boolean g_quit variable and inside it I'm
calling the frame() method of my osgViewer::Viewer object among other things.
Most examples I have seen are using the run() method but that seems to have
loop in itself so it's not applicable here. Is frame() the preferable way to do
this? Does it automatically update, cull, draw through that method? I want to
see if I have got this right.
Check the code for osgViewer::Viewer::run(), which calls
osgViewer::ViewerBase::run(), which calls
osgViewer::ViewerBase::frame(). You'll see that it calls everything
that's needed. If you want to, you can reimplement your loop the same
way (for example if you need to do things between the cull and draw
traversals).
Hope this helps,
J-S
