# Animation Nodes: add a new shape, like UV sphere

I'm very new to Animation Nodes, and I'd like to see if I can do some parametric object creation with it (I tried sverchok before that looks great also, but I got some unexplained segfault so I'm trying to see if AN is more stable). Unfortunately, I can't find how to perform this very simple task: create an UV sphere (or a cube/any basic mesh...) directly from Animation Nodes (the object instancier node seems to refer to a node already present in the scene, which is not really what I need).

Is it possible? If not, could you explain why this basic feature is not present?

Thanks!
