Hi all,
in my application I have a couple of strange effects I cannot explain.
In a few words:
It is a C# application in which a user defined control:
class MyControl : UserControl
create an osg viewer via C++/CLI:
_MyControl_Interop.Init(this.Handle);
On the C++ side we have standard stuff:
p_hWND = reinterpret_cast<HWND> (wnd);
traits->inheritedWindowData = new
osgViewer::GraphicsWindowWin32::WindowData(p_hWND);
etc, etc.
On the C++ side I don't have a rendering loop but I call "myViewer->frame()"
only when needed.
The two strange effects are:
1) When the application loses the focus, all the objects and the background
layer often disappear and all I see is the clear color (i.e. the color set with
"MyViewer->getCamera()->setClearColor(...)"). Then I need to set the focus on
the panel again and do another call to "myViewer->frame()" to restore the
correct view. Is this normal? How can I avoid this?
2) After a few calls to "myViewer->frame()", the projection matrix become
corrupted (even if I didn't change anything in the scene), and I need to reset
it. I read this article:
"http://chadaustin.me/2009/02/ind-and-qnan-with-fpfast/": is it right? Do I
need to recompile osg? (currently I'm using precompiled libraries).
Best regards.
Giulio
