Few of our recent projects done between 2008 and October 2009:
-----------------------------------------------------------------------------------------

1) Web & mobile dating service.
Developed server components and related mobile clients.
Server components for this service such as:
• log4net
• container for task – environment for periodical executing some task which realize a part of business logic
• multilingual provider
• specialized windows service
• Wurfl .NET wrapper
• geolocalization functionalities, Microsoft SQL database and quadro-mapping dump
• twitter and facebook api implementation
• SMS messaging service – SMSC working on SMPP protocol or GSM modem, handling multipart smses, encoding, database storage, etc

Additionally our developers provided iPhone client application for service which accompanied the web with dating possibilities and rich iPhone interfaces.

Technology: C# (.NET 3.5), Objective-C, OpenGL

2) Mobile guiding system designed for the visually impaired in Paris subway stations.
We have developed a mobile phone application that enables a phone to pick up on Bluetooth signals that are broadcasted by tags laid out along the subway corridors. The phone then produces vocal guiding to provide the user with the information he/she needs.

Technology: Symbian OS v9.2 for platform s60 3rd edition, targeted devices were Nokia n95 and Nokia n81, for development was used Carbide C++

3) Building facade illumination CONTROLLING SOFTWARE
The project was to build the control and simulation solution that would be capable of controlling 5.100-m2 LED Facade.
Concept assumed that the whole system could be open to external control by sending to its network packages based on specially designed protocol. For user convenience the simulator part was developed which shows 3d model building with facade ( additionally surrounded buildings ) illuminated with LED lights.

Technology: DMX512 light protocol for control purpose and additionally ARTNET, UDP network solutions, C++ programming language and WxWidgets cross-platform tool-kits for GUI creation purposes, OpenGL library was used for generating 2d and 3d graphics for simulator part

4) 3D Rotation Modeler
The idea behind it was to give the user possibility to create 3d models by drawing 2d stroke on the screen. In real time 2d stroke is rotated on its Y-axis giving 3d object as the result. Application was extended by number of point and line editing tools. The creation of 2d strokes was based on the math equations for Hermite Curves.

Technology: C++, OpenGL, Wacom touchscreens

5) Fabrication Stations.
Three applications for managing fabrication process with use of 2D printer, laser cutter and 3d printer. The functionality of stations was extended with specially developed technologically advanced model editing library with features like 3d object slicing, 3d object simplifying and 3d object format loaders and converters e.g. STL to OBJ or OBJ to 3DS.

Technology: J2SE and Alice scene-graph, C++, WxWidgets cross-platform toolkits, WxArt2d
