The entertainment industry's digital technology advancements have brought about the era of Cinematic Virtual Reality (cVR), showcasing its ever-increasing complexity and diversity. With the presence of technological innovations such as Insta360 Titan, OZO, Jaunt, and KanDao Obsidian Pro, the capture and display of 360° ultra-high-definition video that aims to offer an immersive physical and visual experience on both big screens and portable devices is gradually becoming accessible to the everyday consumer. Notwithstanding the advancements, the current 360° stereoscopic spherical cinema (3DSC) filmmaking still parrots the narrative and aesthetic schemas of flat 2D films, and, in doing so, it binds the medium into an inelegant representation, unfit for the new digital setting. Because 360° film production inevitably gravitates towards the breakdown of authoritarian structures, it produces a novel narrative and visual regime that departs from classic spectatorship and moves towards an episodic neuro-visceral immersion (ENVI), where, as warranted by XR technologies, its residual, platial experientiality, is best served when a narratological approach is applied. This dissertation therefore undertakes comprehensive and rigorous research at the intersection of narratology and immersive technologies, as it aims to push the boundaries of both fields beyond what has been characterized as "emerging vectors of narratology" to form a specialized sub-field of narrative studies focused on Cinematic VR. The overarching goal is to propose a 3DSC narratological typology that can aid both industry professionals and academics in developing effective stereoscopic immersive narratives not contingent on specific VR technology. Additionally, the typology is tested within rhizomatic space to substantiate whether the communal template of spectatorship provides a foundation upon which social, aesthetic, political, and human interactive models can be built and whether the cVR format itself encapsulates rhizomatic qualities inherent to the medium of 360° film.
