Program comprehension for live algorithmic design in virtual reality

Algorithmic Design (AD) is a design approach based on the development of computer programs to describe architectural models. The programs’ outputs are digital architectural 3D models, which are visual by nature and, therefore, benefit from immersive visualization. Live Coding in Virtual Reality (LCVR) is a methodology for the interactive development of AD programs while immersed in Virtual Reality (VR), favoring a more intuitive development process for architectural designs. However, complex buildings tend to require complex AD programs and, despite the added visual aid, as programs grow in complexity, it becomes harder to understand which parts of the program were responsible for which parts of the model. Moreover, LCVR introduces a new level of complexity: interaction with both model and program in VR. This research proposes to ease the programming task for architects who wish to code their models in VR, by supporting program comprehension in the LCVR workflow with traceability and refactoring mechanisms. These features will help users interact with their designs from within the virtual environment.
