This paper presents a study that aims at exploring the possibilities brought by
recent technologies to visualize in a quasi-real way an existing building survey.
By doing so we discuss two recent technologies that are useful for the ideation
stage in architecture design, 3D laser scanning and Immersive Virtual Reality,
namely for interventions on existing buildings. To do so a 3D scan survey was
performed to an existing building and the resulting 3D point cloud model was
used in an immersive Virtual Reality environment during the rehabilitation
design for an existing building.
The results show that point cloud models bring more rigorous and consistent
information about buildings than traditional surveys. Additionally, the
use of immersive virtual reality to visualize point clouds enables a type of
experience of the “real” building not possible by any other mean. Indeed, virtual
reality provides designers with an incredible source of authentic building
elements that allows them to have a quasi-real experience of the building.
The visualization of such point cloud in immersive VR enables to transport
designers to a new dimension where not everything from the existing building
has a place but just the main essence of it levitating in a virtual world.
