I think these methods would be much better, since they would be doing things "right". >> seed graph example >> >> http://heybryan.org/~bbishop/docs/repo/2008-12-11/2008-12-11_waterlifting.gxml >> >> screenshot of that example in GraphSynth >> >> http://heybryan.org/~bbishop/docs/repo/2008-12-11/2008-12-11_waterlifting.png.PNG > > [Offtopic: Interesting :) Are these energy based constraints ? What are the > coloured edges ] The colored edges were a cheap hack I implemented in GraphSynth. You see, when you get a seed graph, you know that you have some rules in your ruleset that are going to replace certain nodes or subgraphs or something, but what you don't know immediately is whether or not your graph is solveable. It's entirely possible that your ruleset (domain knowledge, I guess) isn't complete, so what I implemented was a way to color the edges and nodes to represent whether or not there's a rule that recognizes them. This way, we don't spend a few hours going through hundreds of thousands of designs all only to realize that we weren't ready to begin. - Bryan http://heybryan.org/ 1 512 203 0507 ------------------------------------------------------------------------------ Apps built with the Adobe(R) Flex(R) framework and Flex Builder(TM) are powering Web 2.0 with engaging, cross-platform capabilities.
