Interstore VR Architectural Visualization
Client: Interstore - Schweitzer
Standalone VR architectural visualization toolkit developed for Interstore | Schweitzer, a global leader in retail design. Interactive 3D environments with millions of polygons running at a stable 100 FPS on Oculus, featuring a real-time material and structure customization system.
VR Architectural Visualization Toolkit (Interstore | Schweitzer)
The Client
Interstore | Schweitzer is a family-owned group headquartered in Zurich, founded in 1927, and a global leader in retail design and shopfitting with over 800 employees across 5 continents. Through its creative arm Interstore — an independent design agency with offices across Europe — the group designs and delivers store concepts for some of the world's largest retailers, including Carrefour, Waitrose, EDEKA, Migros, and KaDeWe. The standard workflow for presenting concepts to enterprise clients relied on complex 3D models produced in Cinema 4D and CAD tools, which were difficult to explore intuitively without specialist knowledge.
The Project
The goal was to build an interactive toolkit enabling Interstore | Schweitzer's enterprise clients to independently explore, evaluate, and customise the retail structures designed for them — with no software expertise required. The solution needed to run on standalone Oculus VR in fully wireless mode, delivering an immersive, cable-free experience during client presentations.
Real-Time Visualization and Interaction
The toolkit was developed in Unreal Engine 4 with C++ and Blueprint, featuring a real-time environmental interaction system that allows clients to modify materials, colours, and structural configurations directly while exploring the environment. Every change is applied instantly without interruption, turning the presentation into an interactive co-design experience.
Optimisation Pipeline
To ensure stable performance on standalone VR hardware, a mesh optimisation pipeline in Python was engineered to automatically process models imported from Cinema 4D and CAD, reducing polygon complexity while preserving visual fidelity. The result was a stable 100 FPS on standalone Oculus VR — a critical threshold for a wireless VR experience free from perceptual discomfort.
Twinmotion Pipeline
For particularly complex environments — running into millions of polygons — a dedicated Twinmotion pipeline was developed to automate composition stages and drastically reduce preparation times for large-scale projects.
Deliverables
Three complete architectural simulations were delivered for European enterprise clients in the grocery and warehouse sectors, each tailored to the specific brand identity and layout requirements of the client.
