What Is a Digital Architectural Walkthrough?
A digital architectural walkthrough is an immersive, simulated tour of an unbuilt or existing architectural space. Created using powerful real-time rendering engines, these walkthroughs allow users to navigate and experience a design in a realistic, interactive 3D environment. They have become an indispensable tool for architects, interior designers, and real estate developers to validate designs, present concepts to clients, and market projects long before construction begins. They range from simple pre-rendered animations to fully interactive virtual reality (VR) experiences.
