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!

Krestianstvo update: New UI and Cog VM

Happy to announce that from now Krestianstvo SDK is running on the new Cog VM (Windows, Mac OS X, Linux Ubuntu 10.x are tested).

Also the new graphical user interface was introduced, including russian and english versions.

Island to island connection through local network is now possible and works just from the main window. OSC features now work properly.

Download

Below is the introduction video to the updated SDK:

[RU]

Рад сообщить, что отныне Крестьянство SDK работает на новой Cog VM (Windows Vista, Mac OS X 10.6, Ubuntu Linux 10.x проверены).
Кроме того, представлен новый графический интерфейс пользователя, в том числе на русском и английском языках.
Остров на остров соединения по локальной сети теперь работают, с возможностью запуска и из главного окна программы.
Ошибки в OSC функциях исправлены.

Man'J - running Arduino, Krestianstvo and SuperCollider

Creating music in movement by interacting with people and architectural objects in realtime.

Video shows the Man'J chair prototype with built in Ultrasonic sensor, controlled by Arduino board, open sourced software Krestianstvo and Supercollider.

Krestianstvo SDK 1.1 is avaliable

Krestianstvo SDK 1.1 is available for download and now it is based on the new Squeak 4.1 image!

SDK includes:

1. Working version of Collaborative Curved Space Explorer
2. Examples of Seaside 3.0 and Open Croquet integration in web browser with Comet support.
3. Examples of Collaborative coding trough web-browser on several images running Open Croquet
4. Open Sophie CSS/XUL logic for describing Tweak user interfaces.
4. Math examples on matrices and vectors in Krestianstvo's learning 3D space
5. OSC remote controlling support
6. 3d vision (red/blue) support
7. Tool for building multi-pixel projection walls or CAVE

and more..

Happy exploring!

Open Croquet running on Squeak 4.1

Yes, now it is possible...!

This is very experimental, but working announce.
Open Croquet code from 1.0.18 SDK is now working in new Squeak 4.1 image and even ready to run on Cog VM.

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.

Чтобы 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!
