Thanks Andreas For Rendering the scenegraph while traversing the nodes , I can leave out the nodes which I dont want to traverse by setting its travmask as 0 . But I have a confusion as to how to render those nodes which I want to render as I traverse them , because I think I cant use simplescenemanager for that . By the docs I understood that may be I can do like this 1) traverse node by node and render some nodes by - RenderAction *ra = RenderAction::create(); ra->apply(someNode) .
But when I saw some code sample as to how to use renderaction in place of simplescenemanager , it was done like - window->render(renderAction); But in this way I wont be able to render node by node . Should I go through the simplescenemanager code to understand more on how to use renderaction to render while traversing? thanks Shailesh On Sun, 25 Jul 2004 Andreas Zieringer wrote : >Hi shailesh, > >for calculating the number of triangles you can use > >UInt32 calcPrimitiveCount(GeometryPtr geo, > UInt32 &triangle, > UInt32 &line, > UInt32 &point); > >in OSGGeoFunctions.h > >Well writing your own RenderAction is quite complicated.
