better viz spanning tree
by Craig Latta 18 Mar '07

Hi-- I rewrote the Nexus spanning tree code to give the spanning tree a strong bias toward selecting subclass and instantiation relationships in the graph. Exploring the graph in Walrus makes a *lot* more sense now. http://netjam.org/spoon/objects.graph.gz -C -- Craig Latta improvisational musical informaticist www.netjam.org Smalltalkers do: [:it | All with: Class, (And love: it)]

Hi Jon-- > The big movie requires the narration .AIF file in order to play. Oops, fixed. > One thing I found that was really useful when I did a graph analyzer > is to include the names of the references (inst var name or index). Yes indeed; just like all the nodes can have labels, the references can as well. It's certainly essential, I just haven't written them out yet. Oh: the data file for the movie's graph is available[1]. If anyone wants to explore around it in Walrus and tell us of interesting stuff, I'd be delighted. :) thanks again, -C [1] http://netjam.org/spoon/objects.graph.gz -- Craig Latta improvisational musical informaticist www.netjam.org Smalltalkers do: [:it | All with: Class, (And love: it)]

Spoon progress 2007-03-13: Nexus reference visualization
by Craig Latta 14 Mar '07

Hi-- Well, I broke down and wrote some code to calculate a non-cyclic spanning tree for an object memory reference graph, so now I can use Walrus[2] for visualization. It's nice! Check out the demo movie I made (in small[3] and original[4] versions). This could be the basis of an extremely powerful extension to the interpreter simulator; I assume it'd be a fun Croquet project. Alan Lovejoy suggested the name "Nexus"; I like it. More to come... thanks, -C [1] http://netjam.org/spoon [2] http://www.caida.org/tools/visualization/walrus [3] http://tinyurl.com/2akd83 (movedigital.com) [4] http://tinyurl.com/33gah7 (movedigital.com) -- Craig Latta improvisational musical informaticist www.netjam.org Smalltalkers do: [:it | All with: Class, (And love: it)]
