[osg-users] Getting a list of all textures (including the ones used by particle systems) in a scenegraph

[Harash Sharma]

Hi all,
   I have a requirement to build a list of all textures used in a scene graph. For this purpose, I have used a NodeVisitor derived class with the apply function given below. 
Problem:  I am not able to get the details of textures used by the attached Particle systems. I would be very grateful if someone can help with some hints / pointers.
Regards 
Harash 
Apply Function:
----------------void
{ 
    osg::Node* Ptr = &searchNode; 
    osg::StateSet* state = Ptr->getStateSet(); FindTextureVisitor::apply(osg::Node &searchNode) // get the state set for the node    osg::StateSet::TextureAttributeList Attr; //         Attr = state->getTextureAttributeList();     if(state != NULL) {        intSz = Attr.size();        // for all the attributes, find the ones related to texture            osg::ref_ptr<osg::Texture> texture = 
                                                                    (j,osg::StateAttribute::TEXTURE));        // if a texture is found            {            if(texture.valid())                // This is a valuable node containing texture                foundNodeList.push_back(&searchNode);                // also store the Texture object related to this node so we                 // don't have to repeat the call to get Texture attribute List                foundTextureList.push_back(texture);                // Now search if the texture has already been used by an earlier node                // get the image related to the texture                osg::ref_ptr<osg::Image> texImage = texture->getImage(0);                // check if it is already in the list        
         std::string filename = texImage->getFileName();                intTexSz = foundImageList.size(); // TextureList.size();                        flag = 
                    }
                }                boolflag = true;                for(intk = 0; k < TexSz; k++) {                    if(foundImageList[k]->getFileName() == filename) {false;                        break;                if(flag) {                    // No it is not on the List                    foundImageList.push_back(texImage);
                }
            }
        }
    }
    traverse(searchNode); 
}                 // add it to the node list        for(intj = 0; j< Sz; j++) {dynamic_cast<osg::Texture*>(state->getTextureAttribute
