Blender "Sprint" in Innsbruck (update 21.6.2006)

Post by xype » Mon Jun 19, 2006 12:55 pm

Hey guys,

I'm part of a group that wants to organize a 5 day Blender development "Sprint" in Innsbruck at the last week of August. The idea is to invite 10 developers to Innsbruck for 5 days (airplane tickets, hotel and food will be provided for) to work on a variety of topics.

Update: The goal of the sprint changed to a pretty broad "CAVE must work with Blender". The GIS interoperability is not a concern anymore and the main thing is that an elegant workflow is established for getting the 6 workstations used for the 6 CAVE projectors to work seamlessly with Blender data. So the content can be anything from a VJ environment to an architectural walkthrough or an ARToolKit installation. /update

But since the whole project would also serve to support Blender development in general, I want to ask the community if there are any other topics that a 5 day development sprint could be used for? Basically we want to couple some of our own selfish interests with those of the community and allow 10 developers to meet in Innsbruck, code, hang out and have a good time.

Update: We're not fixed on the 10 number anymore, and it seems that the Zukunftszentrum would also prefer a smaller group - but that has yet to be finalised.

So, here are the questions I would love to have answered in order to plan the thing:

1) Are there Blender developers experienced with either CAVE development or, as a CAVE experiment, Verse development who would like to join?

2) Do you have an interesting pet project that you would like to spend 5 days on that involves the game engine, input devices or even documentation? If so, post a proposal and a short bio or examples for us to evaluate.

3) How would you like such a Sprint to be organised? While we have some ideas ourselves, we'd love to know whether we should prepare some extra stuff for the developers. Maybe some books or research material or simply the ability to print, scan or build code on a dedicated server.

Also I'd like to point out that we are open to the content part as well – if there are people who are working with Blender (as an architectural visualisation tool, for example) it would be great to have them on board for input so we can try to improve Blender for them.

Update: The organization of the Sprint has now been handed to me, so I'll be able to get back here with more details later this week. I hope we can get enough funding to invite some people from overseas as well. /update

Please add your comments on questions, I'm looking forward to hearing from you guys!

Hi, I am a czech art school student, working with blender a lot. So I surely would like to join. I'm not a C++ coder, but i have done many art projects with blender(generated landscape, some dynamical environments, 1 installation, some games). I have experience with networking blender - I used ARToolKit for my installation, and used a network protocol to send tracking data from Macromedia Director. I also coded BlenderVJ in python, a VJing app in Blender which used midi libraries.

I already wanted to attempt to build a CAVE system at our school, but I hadn't enough time and computers/projectors.

So, if the project is done in C++, then I cannot help , but I believe I could bring some good ideas about what could be done, and maybe develop some art for the demo.

I also can speak german good (studied a bilingual school), but i assume the communication lenguage would be english anyway...

I'm not sure how I'll be with my time at that time, but I'm sure I'll know it at least 1 month in before, so I can let you know then.

Heya,

I guess networked Python and ARToolKit would be a good start for a CAVE Blender installation. And we need content guys as well anyway, so consider yourself on "the list" :)

Dunno what the "official" language will be - if enough international guests join it will be english for sure. Still that should be the lesser problem.

I hope you can find the time!

hi

It seams to be good idea to work on some collaborative project with few other guys in Blender.
I like to join your development party.

I'm not pure programmer same as pildanovak, but I'm working with Blender Game Engine for 4 years and I have done some games already.
like:
http://o----o.info/swing/
http://o----o.info/E_S/
or my last project
http://bfight.org


I think that build up cave will not be a problem during 5 days but the content is also important.
I'm not sure how you wanna use GIS data.
I know GIS quit a bit but as far as I know they include coordinates, hypsography etc. So only think you need to use is importer and then pretty reduce the polygon amount. Depends how accurate are your GIS data.

I'm basicly artist so if you like to have in your group someone like that I'm down for it.
You can find more information about me on my webpage http://o----o.info

Cool. Someone with GIS experience would certainly be helpful (since I have none). The idea is to use Open 3D GIS in connection with Blender in order to display geological data. To be honest, I'll need to read up on the whole thing a bit myself (the Open 3D GIS website seems down at the moment, though), since I only got a printed chart on "how it is supposed to work".

I'll also post a note at the local university to see if there are any experienced developers available for the project.

I think you ought to find someone who will write a reader(importer) for GIS.
Maybe it already exist.
maybe...

strange, just two days ago i thought maybe sprints like they do for python and other open source projects maybe would be a good idea for blender too and now i see this thread. i hope you will find enough participants! :) what "group" does sponsor this?

http://www.zukunftszentrum.at/

It's a state-funded organization that is specialising in topics regarding the future of work, the local area as a workplace and the changes in the working environment that will happen in the near to long term future. Lately they found an interest in Open Source and are looking for ways and ideas to integrate Open Source in the various processes in the industry.

Blender is interesting to them as it's both an animation and a realtime visualisation tool and right now they are testing the waters with some smaller projects to see what the response is and how one could support Open Source and get something in return. The people there have a lot of contacts in goverment and the industry, though, so we hope that we can get some more exposure for Blender that way.

I'm allways game for a 5 day blender development fest. :)
C++ isn't really my strongest language, but I can get around in it.

I don't have any CAVE experience. I am however pretty familiar with the
blender code base.

A proposal for something to do would be clean up the SoundSystem. I've already started on this just haven't been able to find the time to finish it.
I'd like to move all sound code to the soundsystem, port over intrr's SDL
version of the soundsystem from instintive blender, and just clean things
up in general.

I'm up for working on anything blender related though.

I have worked a bit with an Onyx based CAVE-like environment,
using the SGI Performer libraries. I have informally looked at
doing a CAVE Blender thing in the past, but I was under the
impression that the lack of multi-display support in GHOST was
the main problem to getting this happening.

Carsten sent me a demo a long time ago that uses three
instances of Blender (a front view, and two side views) that
communicate using python to do some networking. You might
ask him for a copy of this demo to look at. Maybe a similar
thing with a verse backend would do the trick?

If my knowledge of C++ and the game engine was stronger,
I'd definitely be interested in this.

Regards,
Chris

Great, can you send me Carsten's E-Mail addy per chance? The synchronised Blender thing would be enough for a start and the verse thing can then be implemented later on (if it proves to have more advantages in first place). Carsten is from Germany, right?

Hello, I work in the VRCenter at UALR in Little Rock, where we have a Cave. I admit I'm not much of a programmer, and I havn't used anything beyond cavelib, but I'm interested in the result of this.

I've sent you an email too.

Dear Samo,

I'm interested in working on the Blender Development Sprint for the CAVE environment as a content provider and application integration tester.
My input would be my work on the architectural previsualization project "Brasilia 3D". The project is real time is a helicopter flight over the city of Brasília, capital city of Brazil. Modelling, texturing and real time programming of the scene is were done in Blender and Python. We presented the project at the Blender Conference 2003.

Due to the great size of the data, the project has reached some of Blender`s limitations regarding mostly culling, level of detail and CPU and memory load. These are areas which could be improved for better real time performance.

We have shown the projects in exhibits with monitors or projections and it would be a dream come true to port it to the CAVE system. And would be great to be with all you Blender and Python gurus.

The site has more information and some snippets of the whole project (small areas without motion, just rotation). The full project, which is not online, permits full freedom of move across the whole city.

Hy Xype

I am VERY interested on your proposal, I've have been only 8 months in contact with blender, I have been in 3D for educational purposes since '96. Now I run the VR lab at the University of Colima.

I really would like to install cave equipment here and think than it is posible to Blender to make it.

Skills: problem briefing, programming (short experience with python, have to say 8 months)
