Ton Roosendaal invites us to IRC chat. freenode server and #blendercoders channel I use X-Chat programm to connect IRC when you choose from catalog reenode server (allready in catalog) than use commanD; /join #blendercoders

enzyme69 commented 10 years ago

It's been a while since I use IRC! how to connect to this? I connect to IRCNet and then at #blendercoders I see nobody. I think Linus, Nikitron and Dealga can represent Sverchok :+1: I'll be watching the conversation --- if I can actually connect to the IRC thing properly.

enzyme69 commented 10 years ago

Oh ok, I got it:

freenode server and #blendercoders channel => I should have read this line properly.

I am in and hanging out as blenderotaku or blendersushiguy or something like that.

zeffii commented 10 years ago

Ton suggested that we start following the mailing list for GSOC and keep communications with the Dev responsible for NURBS modernization public. Before we do that perhaps we can make a small list of API accessors that would let us get started with NURBS. Perhaps ordered by projected ease of implementation.

I think hooks similar to mathutils.geometry.interpolate_bezier(p1,p2,p3,p4, count) -> verts would be my first request. Something like: 

  > in: set of control points (nested list to show u, v)
  > in: order u , v 
  < returns the verts and faces

(ie something to do this https://gist.github.com/zeffii/10727363#file-brockus-py without all the fussy stuff) The fact that i can't explain this with enough detail suggests that I shouldn't be the one to contact him :)

ly29 commented 10 years ago

Short term a set of such function would be nice. Long term a bmesh like interface for nurbs is needed.

From: Jonathan deWerd
Subject: [Soc-2014-dev] Weekly Report #2: NURBS Modernization

This week's progress:
- I can successfully load order 2, 3, and 4 NURBS curves! To be clear: no surfaces yet and I haven't added support for a bunch of .3dm features, from small ones (not-open curves with irregular knots) to big ones (trimming). But I'm not held up on these, I'm hung up on...
- Integrating opennurbs into cmake. I got my first result by manually tweaking the Xcode files that came out of cmake but this is no good in general. I've put opennurbs in the "extern" folder and I'm still working out how to persuade cmake to generate the appropriate build files.
- Got a stakeholder .3dm testfile. It's not production data but it tests for a specific cut that was needed in production. I have lots of .3dms now: I have 3dms that I made, 3dms from stakeholders, and lots of 3dms from the Rhino example libraries.

Things that were done this week that weren't progress:
- Reading trimming literature

What I want to have done by next Friday:
- Integrating opennurbs into cmake
- Surface import (ideally including trimming although I suspect it will slide another week)
- Midterm proposal (didn't really work on it this week)

Cheers,
Jon
nortikin commented 10 years ago

and conversation go on hard on nurbs afraid to send message wrong. it needs particular subject. if i copy that subject, will try.

nortikin commented 10 years ago

Yes, I tend to agree. Besides, once I get cmake to link it properly (that's the hangup right now but I think I'm pretty close to fixing it) then I can probably chop out 60-80% of that code to keep the size down. If we ever need to update the library (unlikely; Rhino probably wants to maintain backwards compatibility as much as possible and it's unlikely we'd support a new feature of theirs for some time after release) we could then just cherrypick the "hatchet-job" commit.

nortikin commented 10 years ago

writed, waiting of answer. Join asked of curve optimisation, curve evaluate from first to last point (not segments) and for NURBS with UV. If you have requests - write them.

NURBS modernization coder : blender wiki page with proposal: http://wiki.blender.org/index.php/User:Jjoonathan#Bio

nortikin commented 10 years ago

i had secret conversation with GSOC-2014-developer, Jonathan. Now he says that he can do uv evaluation of point on surface, he busy nevertheless with nurbs import-export from-to maya-rhino etc. this will take over month or more. NURBS was taken to deep draft long ago, so now much to do. Also I asked for curve point evaluation - to find interpolate points on curve from start knot to end knot. if it will, than we could make cool stuff with lofting!!! no matter have or not gaps between initial curves, we could make polygonised surfaces with quads by lofting them in different ways. I'm dreaming of it. He not promis be quick. because much to do there.

nortikin commented 10 years ago

and his answer was '42' I'm in IRC https://github.com/Cfyzzz/Scripts/blob/master/sverchok.py old version of sverchok ))

zeffii commented 10 years ago

2013-09-03? is not even so long ago :) such a big difference.

nortikin commented 10 years ago

?? i readed about 2009

nortikin commented 10 years ago

Jonathan made first commit to NURBS... hope he will acheave much. good luck to him

nortikin commented 10 years ago

Jonathan catch a cold this week, as i understood. and did not nothing. tesselation is needed, he doing it. and some troubles in this job occure.

nortikin commented 10 years ago

wow! kaito: so so, well well, mail from Dassault kaito: they want to reach out to open source 3d projects

zeffii commented 10 years ago

I use draftsight for fun :)

nortikin commented 10 years ago

hope it will grow to something

ly29 commented 10 years ago

Draftsight is a very nice for what it is.

<Severin> axys, I've already implemented tabs as a own button/widget type so you could use them anywhere in the UI
<Severin> but it's not in master yet
<Severin> e. g. http://www.pasteall.org/pic/show.php?id=73906
<Severin> i can send you a patch so you can try it yourself if you want to

somebody want go to blender conference? to present sverchok i'm far away from Amsterdam. And for now afraid to take foreign passport and visa to EU. Because of american intervention to our country. I hope on Linus or Agustin or Dealga if it is close there for him. What you think?

nortikin commented 10 years ago 
Call for participation
We now accept proposals for presentations, papers, courses or case studies. As usual we’ll schedule shorter talks (max 25 minutes) in the big theater (seats 180), and have longer sessions (up to 85 minutes) in the Salon (seats 90).

Deadline for proposals: August 20, 2014

Read the call for participation here.

nortikin commented 10 years ago

or maybe we can ask for skype conversation?

nortikin commented 10 years ago

i think we should at least do video presentation... yes. But if you want present sverch, please.

AgustinJB commented 10 years ago

Going to Blender Conference would be just awesome. Doing it to show Sverchok...wow. But yes, we definitely should do something to show sverchok, video or make a proposal for presentation. In case that we are accepted, I would be avaliable to go to Amsterdam. No problem for me.

nortikin commented 10 years ago

here is my proposal for whom to go. there is site recommended by Blende institute http://www.campingzeeburg.nl/index.php?page=prices-and-reservations tent + 1 person 7,- 10,- 11,5

fits for me, 7 euro is ok. but need tent. water and toilet there, i guess.

two+ nights will costs 14+ euro. or if two people, 12+ euro and conference i don't know how much for participants

nortikin commented 10 years ago

ticket for me is 3000+grh, it means 190 euro!!! noway. i will not go anything but bicycle.

enzyme69 commented 10 years ago

I am really very interested. But cost is maybe $2000 Australia at least :| ...

enzyme69 commented 10 years ago

Maybe I can send video recording. I am be the most noob but I will say, with Nikitron, Linus, Dealga, Alex and the many are powerful in term of team :) artist and developer collabs.

enzyme69 commented 10 years ago

If we need to be there physically, I will somewhat prepare for ticket.

Nikitron, if you get Euro 300 will you go?

When is the exact date?

I think I am ready.

ly29 commented 10 years ago

I will most likely not be able to attend.

nortikin commented 10 years ago

Proposal Checklist Please submit the following information by ASCII email to conference(at)blender.org

Deadline: August 20, 2014

Personal information First name & family name (and optional a nick) Address & country E-mail address Title of paper, presentation, workshop or course Brief summary of your proposal (max. 200 words) Outline of technical needs (in terms of set-up for courses, equipment and software needed for presentations, etc.) Brief narrative biography (max. 200 words) – please do not send full CVs Url(s) for visual and/or other supporting material

nortikin commented 10 years ago

So, we need prepare documentation and Linus is most close to Amsterdam from all of us, including Agustin. As we see, Ton compensate only one ticket+dinners+hotel for one person. if someone want present there also, he should pay at least 130+30+30(two days hostel)+trevel. Linus is enough to present Sverchok, and he knows better that others what is going on in update and UI separation.

AgustinJB commented 10 years ago

I totally agree with that. Right now Linus is probably the most prepared to talk and explain what we are doing in terms of coding, and the conferences are mostly about coding, right?

The problem would come if it's not possible to go for him.

nortikin commented 10 years ago

i think we will prepare materials and papers, and if Linus has time and Ton will include him to list, there will no problems. or papers and video presentation or human presenting.

ly29 commented 10 years ago

I'm willing to go. The conference is about blender on all levels, from coding to using blender in all contexts and on all levels. The only common theme is blender so to speak.

enzyme69 commented 10 years ago

Maybe I might borrow money and come over few days. Meet Linus. Say hi to Ton etc

Better to preserve money from this kind of things. waste money for trevelling on 3 days? nonono, please. 2000*2 is mean you trevel on half of year

AgustinJB commented 10 years ago

@nortikin are you preparing some documentation to send?? Tell us if you need help with something.

nortikin commented 10 years ago

if you have wonderfull images or one image - tell. I did not did any preperation. Linus filling list-form to participate. but for october i have nothing

AgustinJB commented 10 years ago

Ah ok, that was what I was asking indeed, if someone has already inscribed.

nortikin commented 10 years ago

@ly29 please, sent materials to blender conference!!!! soon will com 20 august and we will not get in time

Ton Rosentaal writes to Jonathan deWerd,

It is already 2 days past Google's deadline, and you really have to make sure we
get your final report without further delays. The report should handle topics on
both technical as user level. Especially pay attention on presenting the deliverables 
well.

and he answers:

Yep. Sorry for the delay. I was traveling yesterday but today I have all the time I 
need to finish it (due to timezones, my Wed. working day is just beginning).
nortikin commented 10 years ago

so, nurbs done for importing. other tools will be far in future

zeffii commented 10 years ago

I was under the impression that NURBS surfaces would be easier to script on that GSOC branch. Hopefully Jonathan deWerd stays around to at least make sure it is.

nortikin commented 10 years ago

i hope in future we will have all libraries of opennurbs
