[Bf-committers] Defining new node types with Python

[Tom Edwards]

I'd like to create a new node graph type to define how an external game 
engine treats exports from a scene. Similar things exist already 
<http://i3.photobucket.com/albums/y84/starwind168/AnimTree.jpg>.

The bad news is that creating new node types is not currently possible 
with Python, and that the output I want is too esoteric to justify 
building into Blender itself.

The good news is that my design is pure Python does not require anything 
outside the existing API: its output is a small script file, and all the 
heavy lifting is done by an existing external compiler. I could actually 
create it today, and the only missing element would be the visual aid of 
the node editor.

My question, then, is how feasible supporting the definition of new 
node/graph types in Python is. We can already instance and modify 
existing ones...
