<div dir="ltr"><div><div><div><div>Hi Saravanan,<br><br></div>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.<br><br></div>To achieve what you want you'll need to implement your own scheme.<br><br></div>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.<br><br></div>Robert.<br></div><div class="gmail_extra"><br><div class="gmail_quote">On 24 September 2015 at 09:58, Saravanan Sivaprahasam <span dir="ltr"><<a href="mailto:saransivaprahasam@rediffmail.com" target="_blank">saransivaprahasam@rediffmail.com</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">Hi,<br>

I want to restrict the precipitation effect inside the geometry. I am using OSG 2.8.3. Kindly provide me some suggestions to achieve this.<br>
