Hi Jon,
The pixelSize function is an approximation of the mapping, making
assumptions, for the purposes of speed, with the intention of
providing good enough results for most purposes. So rather than being
wrong, is just not accurate for your particular usage model.
The question then really is

Hi Robert,
I agree that speed is important, but the current implementation is only
accurate for applications using near-square frustums. With a very low
aspect ratio the returned pixel size can be as low a half of the true

I added bump mapping to a model using osgFX::BumpMapping, but I need

I suggest you to see the osgshaders example (how osg deals with glsl)
