Abstract

Scene graphs have been a core element of 3D graphics since the publication of Inventor. However, in Virtual and Augmented Reality applications, 3D graphics are often interleaved with and controlled by real-world data provided by pose trackers, cameras and other kinds of sensors. In such a setup, the generalized concept of a Spatial Relationship Graph (SRG) might be better suited as an underlying data structure to describe the application and its components. In this paper, we will give an overview of the SRG concept, describe its difference to a scene graph and provide an example AR application built upon an SRG-based tracking library.
