Defining Geometry Levels for Optimizing BIM for VR: Insights from Traditional Architectural Media

Virtual reality (VR) provides a unique opportunity for sharing culturally significant spaces that are not physically accessible. For an effective portrayal of these spaces, it is beneficial to use digital assets that are developed with geometrically data, such as building information models (BIM). Unfortunately, the conversion of BIM to a publicly accessible VR is fraught with challenges. A process for translating a complex BIM to a curated publicly accessible VR by organizing the elements into four defined “geometry levels” is developed in this work and examined using the case study of the centre block of the Parliament Hill national historic site of Canada.
