[osg-users] [osgOcean] Iam in a puzzle about the realization of osgOcean's 'Glare effect'

[Tian Ma]

Hi,

I saw the code in 'OceanScen.cpp', that 5 cameras in 
'osgOcean::OceanScen::_glarePasses'  were used to render the glare effect.

But I saw the realization code in "water.frag" is just as bellow:
         if(osgOcean_EnableGlare)
        {
            float lum = luminance(lumColor);
            gl_FragData[1] = vec4(lum);
        }
And it looks like that the cameras in 'osgOcean::OceanScen::_glarePasses' were 
not been used anywhere. Will tell me why?


Thank you!

Cheers,
Tian
