    • Provided is a silhouette rendering apparatus and method using temporal coherence in a 3D space. The silhouette rendering apparatus includes: an edge extracting module for extracting edges of a 3D object by using a smooth surface method generating edges on a surface among silhouette extracting algorithms among mesh information representing a mesh shape; a stroke generating module for generating a stroke by linking the acquired edges; and a parameter computing module for determining a related stroke based on camera and object animation information extracted from current and previous frames of the stroke, computing style-related parameters of the stroke, and setting them up. This makes artists freely express silhouette by applying parameters of silhouette edges to a silhouette style having temporal coherence between frames based on a concept that the silhouette edges move in a 3D space. Also, the present invention resolves a problem of temporal coherence of a silhouette rendering style which effectively reflects the shape of a 3D object.
    • 提供了一种在3D空间中使用时间相干性的剪影呈现装置和方法。 轮廓提取装置包括:边缘提取模块,用于通过使用在表示网格形状的网格信息中的轮廓提取算法之间的表面上生成边缘的平滑表面方法来提取3D对象的边缘; 行程生成模块,用于通过连接所获取的边缘来产生行程; 以及用于基于从笔画的当前和先前帧提取的相机和对象动画信息来确定相关笔画的参数计算模块,计算笔画的风格相关参数并进行设置。 这使得艺术家基于轮廓边缘在3D空间中移动的概念,通过将剪影边缘的参数应用于具有帧之间的时间相干性的剪影风格来自由地表达轮廓。 此外,本发明解决了有效地反映3D对象的形状的剪影呈现风格的时间一致性的问题。
