DeltaVR is a virtual reality experience set in the [Delta Centre](https://delta.ut.ee/) of the [University of Tartu](https://ut.ee/). The virtual Delta Building includes several interactive scenes that demonstrate the teaching and research actively done in the Delta Centre.
The application works on PCVR, Meta Quest 2 and 3, HTC Vive, and regular Windows PC platforms. There is cross-platform multiplayer functionality that enables several users to be in the same virtual environment from both VR and PC platforms.
## Build
Download the **[[latest build]](https://drive.google.com/file/d/1Ky4RppQor-D5jHLrOan63M7BvcAN-2yN/view?usp=sharing)** (last updated 21.05.2025)
## Features
### Exploration
DeltaVR features the first two floors of the Delta Educational Building for **exploration and discovery**. There are many diegetic elements representing the studies and research conducted at the Delta Building, such as robotics, the high-performance computing server room, video game development, and student life.
### UFO Bow Game
At the terrace on the second floor, Delta explorers can defend the building from UFO-s using a bow and **achieve high scores**.
### Bolt Self-Driving Car
The courtyard between the Educational and Entrepreneurial buildings of the Delta Centre, the explorers can see the Bolt Self-Driving Car. This car is developed by the [[http://adl.cs.ut.ee/|Autonomous Driving Lab]] of the [[https://cs.ut.ee|Institute of Computer Science]]. If one is brave enough, they can stop the car and catch a ride, simulating both the **feeling of being in a self-driving vehicle** as well as VR motion sickness.
### Space Walk
Where the actual Delta building has a set of skywalks connecting it with the entrepreneurship building, DeltaVR has a set of portals leading to the Space walk experience. In it, one can move in the vastness of space and experience changes in gravity. A fleet of UFO ships react to one's presence and come to investigate the arrival.
### Server Room
On the second floor, one can hear the humming of the servers. Should they investigate, they will find a room of server racks and a large red button. Should they push the button, they will trigger the fire alarm and have the server room fill with harmful invisible gas. This propms the player to escape the room. This largerly auditory experience is noted to be engaging and immersive. It represents the work of UT HPC in maintaining the servers of the University of Tartu.
### Interactive Map
To navigate the two floors of the large Delta Educational Building, explorers have an interactive map. This provides a clear overview of where they currently are and what other interactions are located across the building. Explorers can teleport to a **select interactive experiences**, while others are left for them to discover based on the hints on the map.
### Whiteboard
In the virtual Computer Graphics and Virtual Reality Study Lab, explorers can use spray paint cans to draw on a whiteboard. Surprisingly, this is one of the **more popular interactive experiences** of DeltaVR.
