Abstract Scientists today can collect more data than they can perceive using traditional visualization methods. New technologies and sensors allow researchers to gather dynamic, complex multi-dimensional data sets---all of which must be carefully studied to reveal their hidden patterns and narratives. The authors have utilized an immersive platform to design a new visualization for real-time, intuitive, spatial manipulations of time-based volumetric data sets via a wand-based gestural interface. The resulting work resolves microscopic tissue structures at a human scale in a room-based pixel space, facilitating research, discovery, and in-person teaching and collaboration.

This paper presents the development of a sketch-based interactive digital prototyping method by using the level-set method as the underlying technology. Various deformative operations (e.g., warping, smoothing) are developed by the level-set method to design 2D sketches. Fast and robust numerical techniques are utilized to support the real-time performance of level-set operations. B-spline function-based shape transformation method is developed to construct 3D volumetric data from multiple 2D sketches. Virtual prototypes are then visualized by reconstructing surface models from the volumetric data. Computational cost and memory requirement of the presented method are analyzed to evaluate its real-time performance. Example virtual prototypes are shown to demonstrate the capability of the developed method.
