Abstract
In the recent years the use of touch-sensitive input devices (e.g., tablet devices) heavily increased. Especially for drawing or sketching tasks, these devices - in combination with new user interface approaches - yield many possibilities to optimize traditional workflows. This thesis provides an approach for integrating this new user interfaces techniques into a volume visualization framework. The main goal is to account for the frequently encountered task of selecting specific structures of interest in a volume dataset which can not be separated by a transfer function setup. First, a gesture-based user interface is incorporated to build up a fluid and intuitive workflow without disrupting the user’s attention from the main working area. Further, a sketch-based modelling approach allows the user to easily generate 3D models out of 2D input sketches. These models serve as an initial selection on a structure of interest within a volume dataset. To automatically fit the generated models on the volume features, we present an algorithm for automatic deformation of mesh models on volume structures, resulting in a good approximation of the specific area. This flexible combination of techniques allows the user to achieve selections in a volume dataset within minutes of work. These can subsequently be used for masking, cropping or segmentation operations on the volume.Additional Files and Images
