In part 2 of the 3D City Viewer project, a prototype was implemented as a proof of concept for the objectives of part 1, using UE4, C++ code and Blueprints. The goal was to optimize the existing solution in terms of rendering and feedback performance and to improve the quality of the 3D scene.

The customer was then presented with an offer for a new standalone implementation.

This tool is being developed for real estate agents in the United States.

In addition, data conversion tools based on both Win32 API and OpenGL, as well as Python, were maintained, adapted and extended.

The 3D assets / content are provided by another external company.

Development of alcohol testing devices under WinCE, using C++ and MFC.

The main focus is porting the system from WinCE4 to WinCE 5, verifying the ported functionalities and applications with tests based on CPP UnitTest, and further developing features according to customer requirements.

The second focus is implementing and carrying out integration and unit tests for the entire system and for individual features / functionalities based on the CppUnitTest Framework and Jenkins. This also includes analyzing the test results.

Development takes place exclusively under Windows CE and is tested directly on the target.

The main focus of my work was developing a multi-touch application for AIDA cruise ships based on eyefactive's SDK, C++, OpenGL.

The application can be used by several users at the same time, and the ship is displayed interactively in a 3D scene together with the decks.

The 3D models are generated from Obj files.

Various animations were also developed, for example when selecting and navigating to a deck or POI.

Development Phase 2 of a PCB Viewer (CAM / CAD application), using Qt 5.9 as the application framework and GUI and OpenGL as the 3D renderer, for the company ANS from Hesse, Germany.

As Software Architect and Developer, I was responsible for the specification (which I had created at an earlier stage), design, implementation, testing, and commissioning.

For the UI, I used Qt version 5.7 and later 5.9. The 3D geometric data was rendered using OpenGL.

The 3D objects were loaded from Obj files and rendered in an interactive 3D scene, with options to show/hide, move, rotate, and mirror objects.

Both orthogonal and perspective views were supported.

The application compiled and ran on both Windows and Linux (Ubuntu).

This is the final development for version 1.x.

• realtime life score data, as an additional factor that could change every 30 to 60 seconds.

Porting of the entire project from 32-bit to 64-bit, both under Windows 7, 8.1, 10 and Ubuntu and Redhat (approx. 4 million lines of code; 42 proprietary libraries + 11 external libraries + 3 specific Qt Plugging projects + 2 tools + main application + associated UnitTests).

Tasks during the porting:

• Preparation & research of project dependencies, code analysis, available 64-bit versions of external libraries, development of strategy and test plan
• Effort estimation
• Creating a branch for the porting: git / SVN
• Performing the porting on Windows 10
• Test cases under Windows 10, 8.1, Ubuntu, Redhat
• Performing UnitTests, analyzing test results, testing critical milestones, bug fixing.
• Merging into the main branch
