Resource-efficient shader implementation for immersive narratives on legacy mobile virtual reality platforms

Abstract

In virtual reality applications for legacy mobile hardware, aesthetic decisions are also technical decisions due to limited resources. This research details the resource-efficient shader implementation used for the Sentinella VR game to enable a stylized immersive narrative on platforms like the Oculus Go. The pipeline employs a custom Toon Shader, Inverted Hull outlines, and GPU Instancing to minimize GPU fill rate pressure. This strategy demonstrates that artistic style can be the technical condition that allows a project to run on older mobile VR hardware.
