Abstract
Ghosted illustration is an effective tool to simultaneously visualize interior and exterior structures while preserving clear shape cues. We propose a novel framework that combines 3D blending technique, which uses depth information of the target structure, with the conventional ghosted illustration framework. This combination facilitates natural blending effects tailored to the needs of ghosted illustration. Furthermore, we present how common manipulation techniques (e.g., masking) and illustrative rendering effects (e.g., silhouette mapping) can be integrated into the proposed framework to preserve both clear shape cues and depth cues. For the compositing techniques, we show and discuss the visual results obtained from various combinations of them. This demonstrates that the proposed framework can be an effective tool for ghost illustration.
