Detailed Description

External provides a means to loading objects from external files, such as shaders, textures or models To use, set up the External object with all the pairs of [filename, object] that should be managed externally, then assign the External object, as a value, to the root node of the scene graph that you wish to use external objects with so that when serializing, the External object is initialized and external objects are loaded before they are needed by the rest of the subgraph i.e. auto external = vsg::External::create("mytexture.png", texture); scene->setObject("external", external); // scene uses the texture object somewhere within it.
