Abstract
We present Aperio - an interactive real-time system for visualizing complex organic-shaped 3D models such as anatomy data or medical data. Aperio employs an interaction model based on a mechanical tool analogy via a small set of virtual “metal” tools, such as rods, rings, cutters, and scalpels. The familiar and well-differentiated tool shapes, combined with their initial pose and metallic appearance, suggest a tool’s function to the user. Cutter tools are designed to create easily-understood cutaway views, and rings and rods provide simple oriented path constraints that support rigid transformations of models via “sliding”, including interactive exploded view capabilities. GPU rendering provides realistic real-time “solid cut” previewing of surface-mesh models. We demonstrate Aperio using a human anatomy data set and present user studies to provide supporting evidence of Aperio’s interaction simplicity and its effectiveness for visualizing model spatial interrelationships.

Notes
- 1.
A video of Aperio can be viewed at www.youtube.com/watch?v=KcGfVjDlnpU.
- 2.
It is not necessary to draw completely across the selected object.
- 3.
If a selected model is not penetrated, a point on the rod closest to the center of the model’s OBB is used.
- 4.
We also initially used a separate system with a simplified user interface, similar to the interface of common object modeling packages, as a control for the study but it was found to be too simplistic and was rated poorly by almost all users. The results for this simplified system are not included in this paper but can be found in [15].
