// We really don't need to override Process() here as the default implementation which calls CreateScene() is ok. We
// are overriding it so you can get an idea of what the base implementation does if at some point the default implementation
// is insufficient. For this SimpleCube example you could replace all the below code with "BaseClass::Process(req);".
// Fusion tools pass Parameters between their inputs and outputs. Image, Number, Scene3D, and MtlGraph3D are examples
// of subclasses of Parameter that plugin developers will typically see getting passed between inputs and outputs.
// Transform3DOperator automatically adds an input(In3D) and output(Out3D) declared to take a Scene3D parameters. It is
// the job of the SimpleCubeTool to create a new Scene3D containing the incoming Scene3D and the cube geometry and then
// outputing the resulting scene. If we didn't inherit from Transform3DOperator we would have to manually add the main
// input/output ourselves.
// We're going to start off by setting the output Scene3D to be NULL. This will cause Fusion to fail the render of this
// tool. Later on we'll set the output to something valid if we succeed. This is just to make error handling easier.
Out3D->Set(req, NULL);

// Note that we have to take a copy of the incoming scene rather attaching it to root directly. Any Parameter you get
// from an input (ie. via GetValue(req) in Process()) must be treated as read only. The reason is that Parameters are
// reference counted shared objects. This is kind of unfortunate, but its not so bad because we're doing a shallow copy
// of the node structure and all the heavy data is refcounted across.
