Hi Folks,

I am tring to understand a parameter in the function
osg::CullintSet::pixelSize, _pixelSizeVector. It is computed by the function
osg::CullingSet:: computePixelSizeVector(W, P, M). Could you please explain what mathematical methods it is according to?
And especially, what these parameters following are meaning, P00, P20_00, scale_00, P23, P33?

Thanks a lot.
