Directing gaze in 3D models with stylized focus

We present an interactive system for placing emphasis in renderings of 3D models. The artist chooses a camera position, an area of interest, and a rendering style for the scene. The system then automatically renders the scene with emphasis in the area of interest, an effect we call stylized focus. Stylized focus draws the viewer's gaze to the emphasized area, through local variations in shading effects such as color saturation and contrast as well as line qualities such as texture and density. We introduce a novel algorithm for local control of line density that exhibits a degree of temporal coherence suitable for animation. Animating the area of emphasis produces an effect we call the stylized focus pull. Finally, an eye-tracking experiment verifies that the emphasis does indeed draw the viewer's gaze to the area of interest.
