As many other areas of human activity, the architectural design process has beenrecently shaken by Virtual Reality (VR), as it offers new ways to experience andcommunicate architectural space. In this paper we propose Live Coding inVirtual Reality (LCVR), a design approach that allows architects to benefit fromthe advantages of VR within an algorithmic design workflow. LCVR integrates alive coding solution, where the architect programs his design intent andimmediately receives feedback on the changes applied to the program; and VR,which means this workflow takes place inside the virtual environment, where thearchitect is immersed in the model that results from the program he isconcurrently updating from inside VR. In this paper we discuss the possibleimpacts of such an approach, as well as the most pressing implementation issues.We offer a critical analysis and comparison of the various solutions available inthe context of two different programming paradigms: visual and textual.
