Collaborating with the architectural research team Hanoi Ad Hoc, I crafted an extensive virtual archive of 'The Grid,' which was originally located in the historic Gia Lam Train Factory. This project goes beyond traditional documentation by offering an immersive digital twin accessible via the web and virtual reality, enabling visitors to explore and study this cultural site while engaging with the detailed research developed by the Hanoi Ad Hoc Team in its original spatial and place-based format.

Throughout the ongoing and iterative development of the project, it became clear that optimisation and broad device support were essential. For exhibition at cultural events such as the UN Youth Summit in 2023 and as part of a broader presentation at ISEA 2025, it was important that the work could be showcased across a wide range of devices—from high-fidelity setups to a simple browser window on a laptop. Extensive prototyping was required, and both Unity and Unreal Engine were used to experiment with optimisation techniques. Additionally, methods such as low poly modelling, Gaussian splats, 3D scanning, and various texturing workflows were explored in the development of the final project.
