[Bf-python] Re: BlendIt / friendly BPython API

[Toni Alatalo]

as a little intro to others: Theo has been working for more than a year now on 
a very sophisticated wrapper to BPython in his Blendit project, and published 
it at the conference last week. I'm looking into using it in Orange, to speed 
up the script development time and make them easier to modify (also for the 
other project members). it is currently available at 
http://download.blender.org/projects/blendit/ but will be started as a 
project with cvs etc. in projects.blender.org .. perhaps later today.

earlier we exchanged some e-mails about the API, and yesterday i happened to 
work on duplication which was one of the problem points he mentioned then, 
and this is just a reply to tell him about the method that seems to work:

there is Object.link() that makes an object reuse the data of some other 
object, which i guess is similar to what alt-d and i suppose Dupliverts do 
too..? this is how i used it with Ken Hughes' new Mesh module in 2.4, to 
reimplement the duplivert functionality: (attached is the full source that i 
started yesterday, when am trying to add random variation to positioning and 
sizing of the duplicates .. pretty sucky still but a beginning)

mesh = Mesh.New() #Mesh.Get(target.getData(name_only=True))
mesh.getFromObject(target.name)
mesh.transform(target.matrix) #to have the worldspace coords of the vertices

for v in mesh.verts:
	new = Object.New('Mesh', 'gen')
	source = random.choice(junks)
	new.link(source.data)
	new.loc = v.co
	scene.link(new)
