我们提出了一个交互式系统，重点放在风格化的渲染的三维模型。艺术家为场景选择摄影机位置、感兴趣的区域和渲染样式。然后，系统会自动渲染场景，并在感兴趣的区域进行强调，这种效果我们称之为“风格化聚焦”。“风格化的焦点吸引观众的目光到强调的区域，通过局部变化的阴影效果，如色彩饱和度和对比度，以及线的质量，如纹理和密度。我们介绍了一种新的算法，局部控制线密度，表现出一定程度的时间连贯性，适合动画。动画的重点领域产生的效果，我们称之为“程式化的焦点拉。最后，一项眼动追踪实验证实，这种强调确实会将观众的目光吸引到感兴趣的区域。
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.
