Hi all,
I'm having a problem with current CVS-Version which i did not have using the 1.6
Release (but i prefer svn-release because of enhanced vrml reader :)
i've a setup using several viewports (say vp_0 to vp_n) using their own cameras
and a final Viewport vp_f for displaying a result of the screenshots taken from
(vp-0 to vp_n) by using TextureGrabForeground.
i.e.
for (vp_0 to vp_n)
{
vp_i = Viewport::create();
vp_i->setBackground(mybackground);
vp_i->setSize(0, 0, 1, 1);
vp_i->setCamera(m_myCameras.at(i));
vp_i->getForegrounds().push_back(m_myTexGrabbers.at(i));
}
and similar for vp_f with material texIDs set to texIDs from m_myTexGrabbers.
All viewports are added to my windowsPtr which is an WIN32WindowPtr. The render
action starts rendering vp_0 to vp_n and finally vp_f;
The problem i get is that if i open the window with the main viewport it seems
that the back-buffer into which the whole scene is rendered is
1. bigger than my mainwindow ( i think it's depending on texture size used for
the foreground-grabbers)
2. and a power of two.
I.e. if i scale my window to e.g. 512x512 i can see the whole scene, but if i
scale it for e.g. 513x512 i just see the left half of the viewport (since the
grabber texture size is now set to 1024x512??).
Any Idea how to get around this?
thanks in advance
Klaus
