    [Addon][WIP] Sverchok, parametric nodes for architects.

    ------------------------------ Sverchok -----------------------------


    Site: http://nikitron.cc.ua/sverchok_en.html

    Sverchok is node programing of geometry, but in completely virtual way (with ability to bake geometry to blender). You would work with pure data, as floats, matrixes, lists, formulas, etc. but in height interface level.


    ------------------------------ Sections ----------------------------

    [Addon] Sverchok
    Node-based tool for parametric design, consists of such node groups:

    1. Basic Viz (viewers 3D, text...)
    2. Basic Data (object insertion, text expor/import...)
    3. Basic Debug (notes, prints of data...)
    4. List Main (masking, joining matching,length, delete levels...)
    5. List Structure (shifting, splitting, slicing, reversing, sorting, flipping...)
    6. Numbers (floats, random, integers, ranges...)
    7. Generator (make new objects...)
    8. Vector (in, out, move, drop, interpolation...)
    9. Matrix (in, out, deform, apply, interpolation...)
    10. Modifiers Change (boom, join mesh, fill holes, rem doubles...)
    11. Modifier Make (UVconnection, adaptive structures, sections, voronoi...)
    12. Analyser (polygon center, area, distance, KDTree...)
    13. Beta (many new nodes, offset, eval, reroute, scale, rotate, neurosystem, logic...)

    * in beta section there are 24 nodes for now (02/09/2014).
    ** scripted node from generator has many templates.

    Some time ago discovered new tool - grasshopper and from end of 2012, i started this project, in August 2013 Alexander joined and work started to go fast, than we made completely new version with viewers and data transfering between sockets in November, 1, it was 0.2.0 version. Later sverchok growing much and team becomes larger.
    My idea is to make addon, fully representing Rhinocerros-Grasshopper functionality. I started from mesh modelling. Try to mimic parametrism (parametric style of Zaha Hadid) in python tools. In future aim - to use blender NURBS to generate, to all tha stuff.

    architecture and scripting is a new relationship. please, go on with your project. I know this another project of a parametric software using scripting. the developer is an architect, as well. http://code.google.com/p/openshapefactory/

    Very ambitious ! Grasshopper is a very complex plugin for Rhinoceros. It's been developed over a long period of time by very skilled hands.

    I fear that until proper NURBS make their way into Blender it's pretty useless to do anything. It won't be on the same level with Grasshopper.

    It's best to just try simple stuff and do that really good than try all the sick shit that's possible with grasshopper.

    Maybe when you have something to show you can create a nice site and ask for donations to keep development alive.

    I'm sure a few people will be interested in it, including me.

    Best of luck !

    Say, isn't this possible with Skin modifier too? At least the Kilian Roof Example - I can't imagine that skin modifier would be capable of that? Perhaps the a simple addon then had to do the transformation from given sliders to the vertices/nodes of the curves the skin modifier is used onto?

    Anyway it's good that you investigate that. Probably I didn't get the purpose and real possibilites properly. Anyway, the name grasshopper is very cool.
    (is it a somewhat extension/UI for a more intuitive way to create mathematical objects? excuse my missing understandings of it [I've no sound currently so didn't hear the explanations])

    Thanks. Full NURBS tools not possible yet. So i'll do part, that works with mesh, do simpliest things, make the basics of GH with mesh. I have to make basic bricks to manipulate quickly with classes & defs. Thats all for a moment.

    This week was free to me, & I did that scripts on topics top.
    Ferthere i'll spend free time in it, because it my passion, & interface would be.

    New script - make edges between two selected objects. make third, connecting vertices 0,1,2,3... not nearest, but it could be done, and would

    For 8 march I prepared compliment script. If you have not words to express your delight about some woman, can use this script. Only thing - it is in Russian, but you can change dictionary manually.

    import sys
    import codecs
    import random
    
    def w(a):
      return random.choice(a)
    
    def main():
      if len(sys.argv) != 1:
        print ('чё за базар? командуй и всё!')
        sys.exit(1)
      a1 = ['Ты']
      a2 = ['так', "очень", "офигенски", "просто", 'невероятно', 'супер', 'безумно']
      a3 = ['круто','потрясно','вкусно','улётно','клёво','прелестно','замечательно']
      a4 = ['выглядишь','пахнешь','целуешься','печёшь пирожки','двигаешься','танцуешь','готовишь','поёшь','смеёшься']
      a5 = ['пупсик','дорогая','милая','солнце','зайка','как всегда']
      compliment = (str(w(a1))+' '+ str(w(a2))+ ' '+ str(w(a3))+ ' '+ str(w(a4)) + ','+ ' '+ str(w(a5)) + '!')
      print (compliment)

    Hi nikitron,
    really nice job you did there. Maybe you could make a little tutorial on how to use your script ?
    anyway, i wish you all the best and will be following

    Hi there - I am a long time Rhino user and I am delighted to see that you try to bring some grasshopper functionality into Blender. I wish you all good luck with that. On a polygon level I think this could be quite useful. One can still use T-Splines to convert SDS polys to NURBS patches in Rhino.

    Sadly Blender NURBS seems to be out of dev time now. I started a donation website 2008 but it looks it was always low on the priority. There to be honest were more important parts like BMesh and Cycles to get attention.

    But I would be happy in case Blender NURBS at least would get the same level as Maya Nurbs have. Thats enough for most modelers here and specifically also for applications like Grasshopper.


    Looking forward to this to mature more!

    Thanks for answer. Yes, NURBS is most dependance I cannot walk though. For now i try to make scheme: emptyes(as dots) - splines - lofted mesh. It is hard. Python very slow!!!!
    But Rhino with GH is huge construction, if count addones to GH and addones to addones to GH for Rhino!!! I tired to install all this stuff, beside this my Windows run on virtusl mashine in Ubuntu. You can imagin my dissapointment. So, my Napoleon's plans seems to be limited by NURBs, my time and python.

    one make surface on user formula
    @Nikitron: I have placed the first script into an animated context. So it is possible to 'grow' the surface over time. I based this Formula AddOn on the Parametric Beam Addon which is a frame work for managing mesh generation on a frame-by-frame basis. I do not know a lot about Grasshopper, but good luck on continued development.

    Here are some renovations, I cooperated with Alexander Nedovizin, he made some useability, but not finished yet. And some fixes of couple bugs. Now it will include nodes!!!!! It's amazing, isn't it?

    Hi Nikitron,
    sounds really interesting, but where can we find the script ?
