ArchViz Walkthrough — Real-Time Architectural Visualization

Overview

ArchViz Walkthrough is a real-time architectural visualization of a loft apartment that runs in the browser. Buyers and clients can walk the space at their own pace, switch between its ground and upper storeys, and compare the apartment at sunset and at night. The same scene supports immersive viewing on compatible WebXR headsets.

No render farm, no 40-GB installer, no “viewing available on request”. A link is the showroom.

The Challenge

The demo explores three limits of presenting a property through static images:

• A still image shows one lighting condition. Viewers cannot switch the scene to compare how the same room looks at another time of day.
• Flat images cannot communicate space. Scale, sightlines and flow — the things people actually buy — only read when you move through a room.
• VR property tours usually mean one platform, one app store, one headset model. Real buyers own Quests, Vision Pros and Picos — a tour that excludes any of them excludes buyers.

Our Solution

• Real-time walkthrough — the loft renders live in Three.js/WebGL at interactive frame rates — every step, turn and glance computed on the spot, in the browser, with nothing to install.
• Two-storey exploration — Ground and Upper controls let visitors move between the loft’s levels and inspect the layout from different viewpoints.
• Two lighting moods — the full scene relights between a warm sunset and an intimate night mode in real time — the same space, two atmospheres, one tap.
• Browser navigation — drag to look, click the floor to move, or use WASD on a keyboard. Viewer settings offer further camera controls.
• Cross-headset VR via WebXR — the identical experience steps into immersive VR from the browser — tested and working on Meta Quest, Apple Vision Pro and Pico. One URL serves every headset and every laptop.

Key Features

• Browser-native real-time 3D walkthrough — no downloads or plugins
• Ground and Upper controls for exploring both storeys
• Sunset and night lighting modes rendered in real time
• Drag-to-look, click-to-move and keyboard walking controls
• Full VR support via WebXR — tested on Meta Quest, Apple Vision Pro and Pico
• Instantly shareable: the entire showroom is a link

Results & Impact

ArchViz Walkthrough gives developers, architects and interior studios a working example to evaluate: open the loft, explore both storeys and compare the lighting. It demonstrates browser rendering, navigation and WebXR viewing that can form part of a property presentation or virtual showroom. Material configurators, additional rooms and sales integrations can be scoped separately for a client project.
