Architectural visualisation in augmented reality transforms the way architects, designers, and clients perceive and interact with architectural designs. AR allows for the superimposition of virtual architectural models onto real-world settings. Architects can use AR to present their designs at scale, providing clients with a more immersive and accurate understanding of the proposed structures. This technology enables real-time exploration of designs, including walking through virtual spaces and experiencing the spatial relationships within architectural projects. Architectural visualisation in AR enhances collaboration, speeds up decision-making processes, and contributes to more informed design choices in the field of architecture and construction.
