Scenograph: Fitting Real-Walking VR Experiences into Various Tracking Volumes
summary
Scenograph is a software system that converts a real‑walking VR experience into a tracking‑volume independent representation, then instantiates it by splitting location nodes and re‑placing objects using a tessellation of 1 m tiles and a 3D packing algorithm. It encodes narrative as a Petri net so sequencing, concurrency, merges and conflicts are preserved. A prototype runs on 25, 9 and L‑shaped 8 m² volumes; minimal Goldilocks example needs ~8 m². User study with 12 participants finds perceived realism drops with standard remapping but holds with Scenograph.
