Abstract
The goal of the paper is to introduce a Virtual Reality Model Assessment Platform. VRMAP (for short) is to be a lightweight, simple to use platform that allows users from various fields to easily check out models in virtual reality, as there are few options to do so natively on the headset. The platform consists of a Model Repository and VR client app. Models can be uploaded to the Model Repository and then downloaded and spawned in the client app for assessment or observation. The VR client app is created in Unity Engine using the new Unity XR framework and supports the GL Transmission Format (glTF), a royalty-free, extensible, common publishing format for 3D models created by Khronos Group. Many of the mainstream formats used in 3D printing and computer graphics can be easily converted to glTF and thus imported into the VRMAP. The Model Repository is built using Express, Node, Typescript and MongoDB. It allows for upload, storage, and download of models. Although this implementation is fully functional, it acts as an example and as long as other, more robust implementation adheres to the defined API standard, it will work as a drop-in replacement.
