VR Laboratory

 Head-Mounted VR SYSTEM

Hardware Features

• HTC Vive head-mounted display

• 2 Lighthouse base stations for room-scale tracking (mounted on the ceiling)

• 2 HTC Vive controllers for interaction

• Optional Vive Tracker that can be attached to the KUKA robot arm

• VR-ready workstation PC (high-end GPU; lab network)

Used for

• Single-user immersive walkthroughs of BIM building models

• 1:1 scale model checking: spatial conflicts, accessibility, and design alternatives

• Interactive navigation and object inspection (e.g. rooms, components, materials)

• Teaching and student projects on VR interaction and digital twins

• Robot–VR coupling: Vive Tracker on the KUKA robot arm for

CAVE-VR SYSTEM

Hardware Features

• 4 × Barco F80 projectors for multi-wall stereoscopic display

• Built-in RF emitters + active 3D shutter glasses (multi-user)

• 2 SteamVR base stations for tracking

• Vive Tracker for pointing/interaction in the CAVE

• Xbox controller for navigation/menu

• High-end CAVE PC (RTX A6000 class)

Software Installed

• SteamVR (tracking & calibration)

• Unity (custom CAVE/VR apps, BIM viewers)

• Autodesk Revit

• Navisworks Manage (coordination, clash detection, 4D)

• Custom Unity prefab & code for automatic Revit-to-VR workflow

Used For

• Group visualization of BIM models in an immersive environment

• 1:1 model inspection, clash & accessibility checks

• Interactive navigation and object review (tracker + gamepad)

• ACC-06 teaching: students load and review their own models

• Collaborative digital-twin & multi-user interaction demos

Large-Scale Multi-Display System (Advanced Desktop Mode)

Used For

• Large-scale 2D/3D visualization of BIM and analysis results

• Seamless switch from immersive VR to detailed desktop analysis

• Group discussion of design options, clashes, energy & structural results

• Hybrid teaching and remote collaboration (share CAVE desktop view with online participants)

Together, the head-mounted VR setup, the multi-user CAVE, and the switchable large-scale desktop mode form a single, continuous workflow: build and import BIM models → experience at 1:1 scale → analyze and discuss findings with the whole team—on site and remotely. This enables faster design decisions, clearer coordination, and hands-on teaching (e.g., ACC-06), without duplicating data or tools.
