Dear all, I would like to share with you a customized redesign of the Wave Collapse Function algorithm that works in Processing. My wish is that someone, someday, can port this sketch from Python to Java and make this algorithm available to the whole Processing community (more on that below). What…

Please find below an implementation of the “tiled model”. [com-optimize(1)] The difference is that, unlike the “overlapping model” above, adjacency constraints are not inferred from a source image. As a result, constraints and frequencies (if needed) have to be entered manually (hard-coded). A co…

Great approach, good explanation, interesting topic. One of the best posts I ever read here. I can’t believe no one answered yet. It’s a perfect match for processing. If you understand the algorithm, it should be easy for you to translate it into Java code, even if you don’t know the language yet. I…

[image] solub: possible = {n for idP in W[idC] for n in A[idP][dir]} Well, somebody could translate but some is just gibberish… :wink:

@needfulthing : Thanks for your feedback and the kind words ! If I had more time I could possibly, and laboriously, come up with a Java version but it would certainly be clumsy and inneficient. I would rather see someone with a good understanding of Java data types implement it in the best possible …

[image] Chrisir: possible = {n for idP in W[idC] for n in A[idP][dir]} Well, somebody could translate but some is just gibberish… [image] solub: A = dict(enumerate([[set() for dir in xrange(4)] for i in xrange(ntiles)])) List comprehension | Set comprehension Version 3.x …

Hi solub – this is a wonderful contribution, and I’m a huge fan of this work – and your effort in implementing it and documenting it so clearly. Fantastic. A huge quick question – is the entropy array named “H” by mathematical convention? I’m tempted to post a slight revision of your annotated cod…

[image] jeremydouglass: – to make the code more readable for students and potential adaptors. Given these sketches got some image assets, it’d be convenient to host them (including their root project folder) on GitHub. :octopus:

Unfortunately that annotated code won’t run in PDE due to the comment-indent style – it causes parse errors. I’ve cleaned up solub’s code comments and then renamed most of the variables to make them semantic. So for example: possible = {n for idP in W[idC] for n in A[idP][dir]} is now written: p…

@jeremydouglass Thank you, really glad to hear your feedback ! [image] jeremydouglass: A huge quick question – is the entropy array named “H” by mathematical convention? Yes, I named the entropy array “H” by convention even though it is the entropy itself that should named “H”, not the array…

Very interesting stuff, @solub . Thank you for sharing this. This fit exactly with a personal project and I finally sat down long enough to work it out. Notes: Compared to Python, Java is… verbose. This implementation is object oriented. I did so to keep things straight in my mind. It also does n…
