Using deformations for browsing volumetric data

摘要: Many traditional techniques for "looking inside" volumetric data involve removing portions of the data, example using various cutting tools, to reveal interior. This allows user see hidden parts but has disadvantage potentially important surrounding contextual information. We explore an alternate strategy browsing that uses deformations, where can cut into and open up, spread apart, or peel away volume in real time, making interior visible while still retaining context. consider deformation strategies present a number interaction based on different metaphors. Our designs pay special attention semantic layers might compose (e.g. skin, muscle, bone scan human). Users apply deformations only selected layers, given degree each layer, more flexible facilitating visualization relationships between layers. are controlled with direct, "in place" manipulation, pop-up menus 3D widgets, avoid divided awkwardness would come panels widgets. Initial feedback indicates our valuable, especially showing spatially situated context data.
