Krestianstvo SDK2 users registration is online!


Glad to invite everybody to register for exploring now the OpenQwaq's collaborative 3D forums using Krestianstvo SDK2 and ongoing Krestianstvo's 2 forums (CCSE, Learning math, Collaborative music, Art disks, ect.) in near future.
The registration page is available online now for all: http://www.krestianstvo.ru/register (RU: http://неучи.рф/регистрация ).
As soon as you get the Login and Password, you could enter into the collaborative 3D forums anywhere through the internet. But for that you'll need to download the new version of SDK.v.2.0.2: here or using an alternative link, or update the 2.0.1 one (Monticello repository here: http://krestianstvo.ru:8888/sdk/Monticello/sdk2/).
The main feature of the new 2.0.2 SDK is the new database storage logic, entirely based on XML and taking away the ODBC/MySQL usage. So, the OpenQwaq's service provider (not the Local's one) use the XML based db just as MySQL db, while storing it in Smalltalk class variable and serializing it's tables onto disc with plain XML files. That scenario is suitable for local and internet servers, thus turning OpenQwaq onto really mobile platform. Another feature is directed against Apache/PHP, meaning the coal/web/forum services running on :9991. So, the first step you could look at working online registration on Krestianstvo site and next will be having all admin pages using just Javascript and Ajax, hosted on the same Smalltalk image.

See you in the forums!

Krestianstvo SDK v2 based on OpenQwaq

OpenQwaq is the most awaited framework in the virtual world's development domain!
Four years left after the latest OpenCroquet release and OpenCobalt has done a lot to bring virtual worlds closer to life, but OpenQwaq set the final point!
Now anybody could set up it's own virtual space or forum and do not worry about the underlying network architecture, just create Forums, create content for them and place on the servers through the web and collaborate.
So, everything looks just fine, but... to start own server on LAN or WAN someone need to install Linux, Apache, PHP, MySql and OpenQwaq server itself following config rules and avoiding the pitfalls.
But hey? We are in Squeak/EToys platform, Smalltalk at last.. in the self-contained environment, so why all these third-party tools a needable? (Yes, for: Security reasons, Application services, Streaming, account politics ect). But in learning situation at classroom or in Art gallery during installation all of these features are not too critical.
I decided to explore, how it is possible to have just One-Click OpenQwaq image with server and client on it, that could run as internet or local server or just a client. Image, that in a few clicks could be used by children setting up the classroom's network or artists making performance / installation.
And the Krestianstvo SDK 2.0 as experimental platform was borned!
Comparable to OpenQwaq, I started Krestianstvo2 with only one image for server and client versions (the server one based on Squeak 4.2).
The aim is to start the server with no need of installing any other third party applications (apache, mysql). Of course, some (a lot of) features of OpenQwaq could not be available in such scenario, but the work is in progress...
In the current version, anybody could easily setup the running server on LAN or WAN (the server http://www.krestianstvo.ru has already running the same image as provided for download).
SDK is developed on top of OpenQwaq, so that no part of the original OpenQwaq code in image is modified from the functional point of view. So, SDK image allows to run OpenQwaq Forums just in pure mode. Nevertheless, for localization purposes the String method #translateMe was introduced and was injected into OpenQwaq code for the most of string's objects. Translation process is still in progress too.
SDK works with Russian language support by default!
----------
Try out the running space!
The demo logins and passwords, that's working on krestianstvo.ru

Login: member
Password:
member
Organization: krestianstvo
Server: kresianstvo.ru

Login: guest
Password:
guest
Organization: krestianstvo
Server: kresianstvo.ru
-----------
You could add as new members and new groups in setup, visually.
In main login screen use right mouse button to have the context menu and select: "Add new user...".


Example connection scenario:

1. On the 'A' host you start Krestianstvo with as server (type instead of krestianstvo.ru the in the 'Server:' field).
2. On the 'B' host you start Krestianstvo with IP address of 'A' host as server.
3. Then try to login with l: admin/p: admin (l: member/ p: member) accounts (or add new members in 'A' host (on the main login screen, where is proxy configuration dialog).

So, in final it will be good to have: CoalServices working with local storage database in memory (instead of mysql) with Smalltalk WebServices front-end (instead of apache/php).

Multi-touch table based on Krestianstvo SDK

Here is a video from the recent event, which was held in the "Museum of Science" (Russia, Vologda), where the Multi-touch table based on Krestianstvo SDK was shown. The table is controlled directly by Krestianstvo virtual space and it's objects shared on the Croquet island. So, several such tables could be organized into p2p network and become a really interactive classroom, programmable just in Smalltalk. For recognizing reacTIVision fiducial markers and TUIO protocol are used (based on Simon Holland TUIO for Squeak work). For music synthesising SuperCollider through OSC is connected, using the idea from SCIMP (SuperCollider Server client for Impromptu) and realized in Smalltalk.

Microsoft Kinect sensor in Krestianstvo SDK

Want to share my early experiments with the novel controller from Microsoft: Kinect, fine working in Krestianstvo SDK (based on Smalltalk dialect Squeak/Croquet). Here you could find an interesting list of projects and ideas already evolving using Kinect in different programming languages (c, c++, of, max/msp, processing. java, ect.)
But, why not in Smalltalk?.. And in pure 3D Virtual Space (Croquet), controlling your Avatar with own body and operating on objects just with own hands..
So, using OpenKinect driver, I prepared the plugin KinectSqueak.framework and the changeset for Krestianstvo (source code is avaliable here) with Mac OS X support only for now (Window will be very soon). The latest downloadable SDK is also include Kinect support, so just download it and try the sensor, if you have one..

Happy Kinecting!

World serialization support in Krestianstvo SDK | OWML

Happy to announce an October update of Krestianstvo SDK with it's main feature:

World serialization support


Meaning, that one could freely save a current work, being done in active space and then restore it at any time later. The spaces are saved into OWML text file format (check them in Resources/resources/MySpaces folder).
In the next post, I will write an introduction to this new format. Briefly to say, it is mainly based on Sophie XUL and partially C3X serialization logic.

Some other features: new objects (Text3D), Seaside and Squeak base image update, Cog VM update, UTF-8 encoding is default in Mac VM now.

Happy serializing!

Video cupture support in Krestianstvo SDK (from Scratch / Etoys)

EN:
There are recent great news from Etoys dev-list, that "Derek's new CameraPlugin morph should work on Windows, Mac and Linux in Etoys image" :)
And now it is available and working in Krestianstvo SDK as video window in 3D space (several camera instances support also). Online video is replicated to all participants of an island in realtime.

So to try, just update your recent image or download the latest SDK with CameraPlugin support in it.
CameraPlugin binaries for Mac OS X/Linux/Windows are available here or could be found in Scratch distribution.
When running Krestianstvo world, check the new item "Видео камера" in menu "Инструменты".
Now everything is ready to:
  1. develop the 3D stereo 'real world' vision support, using 2 video-cameras for left and right eyes, then
  2. combine it with 'virtual world' stereo vision (already existed as 3D stereo filter) using some of video tracking technique, and
  3. do all this in real-time

Happy VJeing!


RU:
Прекрасные новости из Etoys листа разработчиков, что "новый Derek's CameraPlugin может работать на Windows, Mac и Linux " :)
И вот теперь он доступен и работает в Крестьянство SDK как видео-окно в 3D пространстве (с поддержкой нескольких видео-камер). Онлайн-видео репликацируется для всех участников соединения в реальном времени.

Ч
тобы попробовать, обновите систему по кнопке "Обновить" или загрузить последнюю версию SDK с поддержкой CameraPlugin в нем.
Двоичные файлы
CameraPlugin для Mac OS X / Linux / Windows можно скачать здесь или они могут быть найдены в дистрибутиве Scratch.
"Видео камера" добавлена в меню "Инструменты".

Теперь все готово к:

1. разработке 3D стерео видения "реального мира", используя 2 видеокамеры для левого и правого глаза соответсвенно, а затем
2. его соединения со стереовидением в "виртуальном мире" (уже существуеющем в виде 3D стерео-фильтра), для этого использовать некоторые техники видео-трекинга
3. делать все это в режиме реального времени


Счастливого Виджеинга!

Avatars collaboration in CCSE shared space

In the recent update, the Croquet TUserAvatarReplica logic for CCSpaceExplorer ship was presented.
It allows to see yourself ship and other user's ships, while flying in the same space at the same time.
On screen shot one's can see the two space-ships, they represents the two Croquet avatars, entered the Curved space. Physically, they are running on two different machines and controled by real users.
So, potentially there could be any number of participants, observing self rotations/translations/ actions in space as and others at the same time.
