[Bf-committers] Blender developer IRC meeting notes, july 17 2011

[Daniel Barbeau]

Hello Sven and all Blender devs,
@Sven: If I understand correctly, you are trying to implement a visual programming language? I don't know how much bibliography you have and if you need more but I thought I'd speak up a little bit : I work for the Openalea project which implements a dataflow visual programming interface that lets us build dataflows pretty much like the compositor in blender ( although not as good-looking in my opinion, we have a taste for cheesy colors :) ). On the business side (ie. not the GUI) the dataflow structure is seperated from the dataflow evaluation algorithm. There are a few of them though the main ones are the "lambda evaluation" and the "discrete time evaluation".  Here are some references:
An early presentation of the project : http://openalea.gforge.inria.fr/dokuwiki/lib/exe/fetch.php?media=documentation:publications:openalea_europython07.pdf (technical things start slide 8)An introduction that presents the lambda evaluation and some other things http://www.euroscipy.org/file/3707?vid=download (start slide 6)This one (http://www.euroscipy.org/file/3707?vid=download, page 102) contains some more details on the algo.
Have a look at their own references, you might find interesting articles for your project as Openalea started from what others had done in the visual programming domain and expand upon that.
