Interactive vessel tracing in volume data

Abstract

On many scales, volume data sets often lack the resolution to allow automatic network segmentation, from blood vessels to molten rock channels; even where humans can see the net clearly. We introduce a precise and dextrous environment for users to transform perception to data, using a stereoscopic view for easy identification of vessels. Our tools exploit the reach-in hand-immersion ergonomics of the Virtual Workbench to allow sustained productive work, and 3D-textured subvolumes to allow interactive vessel tracing in real time.
