I render to an FBO texture attachment the same size as my window. But
when I expand the window and try to resize the texture to match it, I
end up rendering to a rectangle the size of my original window in the
lower left corner of the now-larger texture. It seems like a lot of
people would have tried this by now. Any advice from someone who is
doing it successfully?
I have tried this code that has been recommended in a few emails, but no luck.
mColorTex->setTextureSize(w, h);
mColorTex->dirtyTextureObject();
mColorTex->dirtyTextureParameters();
mCamera->setViewport(x, y, w, h);
mCompositeCamera->setViewport(x, y, w, h);
mMainSceneView->getRenderStage()->setFrameBufferObject(NULL);
mMainSceneView->getRenderStage()->setCameraRequiresSetUp(true);
This seems to be the exact same problem as this unanswered email from
last year. There have been similar threads from time to time as well.
