Global 3D visualization of magnetospheric structures for analysis or model validation has been approached from the standpoint of direct field line depiction or artistic renditions. We present a set of relatively simple algorithms for the visualization of a host of global magnetospheric structures, including flux tubes, drift sheets, and separatrix surfaces. Our approach is to combine the detailed geometry of field line traces with locally known quantities to construct regions-of-interest (ROI) that characterize the physical process we wish to investigate. Global measurements over the ROI are obtained from surface, path, and volume integration. Our data structure allows us to reduce these integrals to operations over the ROI boundary, by exploiting the divergenceless nature of the field. Our approach is very general and is not limited to magnetospheric simulation alone. While these techniques were built with rapid prototyping in CISM-DX, the methods themselves are simple enough to be implemented in other visualization frameworks.
