VRhino II: flow field visualization inside the human nasal cavity

Nasal airway obstruction is a serious and common problem within the field of rhinology. This paper introduces VRhino II, a virtual-reality-based application for the analysis of the airflow through the human nasal cavity. This tool is currently developed within a research project striving to gain better insight into the flow conditions during respiration. The paper's focus lies on a general description of the application's design. Additionally, technical details about the main system components are given.
