Finished Theses Metaphors for Immersive 
Software Visualisation

The aim of this thesis was to explore graphical representations for visualising software in virtual reality.


Software is intangible, abstract and complex. To visualise it, metaphors are quite inevitable. The main concern of this thesis was to experiment with graphical representation of code entities and their relations in a room-scale virtual environment. Since this thesis focused mainly on the design issues, it uses methodology for designing VR interfaces “VRID Model” (Tanriverdi&Jacob) as a core concept for modelling virtual environments and designing interaction in VR.
The modelled environment (working title “SoftWorld”) is based on the data from a software written in Java at HEC Software Development between 2015 – 2016: 23k lines of code, 325 files and 363 Java classes, 80,6% coverage through 139 unit tests (Snapshot 1.2.3. from 16th July 2016 on which most of the static data visualisation are based). The used data metrics about the system comes from SonarQube, an open source quality management platform, and are imported to Unity3D. The metaphors (as models of VR environment) are implemented in C#, developed in Unity3D version 5.5. to run on HTC Vive.


Final outcome (application demo “SoftWorld”) introduces software in a simplified and playable way, so that different users coming to the code later in its life can understand, memorize and discuss the software structure and its evolution. Created virtual environment has three levels which concentrate on specific questions and goals that motivated the visualisation:

Displaying software defects or problems, exploring unit test coverage or reviewing software evolution are some of the created scenarios which interfaces could be used for a general dissemination and support of programming education. Some of the metaphors, e.g. procedurally generated data meshes (Level 3) displaying the software evolution, could be even used as inspiration for highly specific refactoring purposes. In order to do that a lot more serious and narrowed work would be necessary.
SoftWorld as a project has also another level of visualisation, the staging of its presentation in form of “Innovation Show”. In a subtle way, such presentation points out to the cultural techniques of VR and IT work, the techniques of cognitive capitalism – commercialism, playbour (labour as a play) and creative expression.
