Advanced volume painting with game controllers

Abstract

Volume painting is an interactive segmentation technique for volumetric datasets. While volume painting facilitates quickly creating segmentations, e.g., for illustration purposes, segmenting features precisely is often problematic. The volume painting system we present addresses two common problems. First, we introduce several data-dependent painting mechanisms to make precisely segmenting features of interest easy. Second, we use game controllers such as a joystick and a gamepad to create a simple user interface to our system while still providing full control over the large amount of parameters of the painting mechanism. We demonstrate our work giving several examples and compare the effectiveness of the various brushes. We prove that our system is intuitive to use with preliminary user testing. The results indicate that our volume painting framework is an effective, interactive segmentation tool.
