Placing emphasis. In the left image the viewer’s gaze is drawn to the upper-left part of the structure, whereas in the right image (with the same camera pose) emphasis is placed in the lower-front balcony. A combination of visual cues give rise to this effect, including line quality and density, color saturation, and contrast.

Abstract

We present an interactive system for placing emphasis in stylized 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.
