Hi Saravanan, The osgParticle::PrecipitationEffect achieves it good performance by making a assumption that the effect is visible in the whole viewing volume, it has no direct support for constraining the effect to specific regions/geometries.
To achieve what you want you'll need to implement your own scheme. As for OSG-2.8.3, this is an ancient release. OSG-3.4.0 is a far more refined version with lots of useful features, such as latest extensions support that are useful for special effects like precipitation. I would recommend upgrading as this will give you lots more options to work with. Robert.
