在许多应用中，有必要使用视觉线索来说明静态图像中的运动，这些视觉线索不表示场景中的物理实体，但被广泛理解为传达运动。例如，考虑说明锻炼、跳舞或给定运动技术的期望运动的任务。传统艺术家已经开发出技术来精确地指定所需的运动（技术插图），并在图像中提出运动（漫画家）。
在本文中，我们提出了一个交互式系统来合成一个动画角色的2D图像生成艺术家灵感的运动线索来自3D骨骼运动捕捉数据。主要线索包括定向箭头、噪声波和频闪运动。首先，用户将动画分解成包含可以由视觉提示表示的个体运动的短序列。然后，该系统允许用户确定用于说明运动的合适视点，以选择关节层次结构中的适当级别，以及微调用于描绘线索本身的各种控件。虽然系统确实为每个控件提供了从运动捕捉数据中提取的自适应默认值，但它允许进行微调以获得更好的表现力。此外，这些提示是在真实的时间中绘制的，并且随着视点的变化而保持连贯的显示。
我们证明了我们的互动系统的好处，对各种动作捕捉序列。
There are many applications for which it is necessary to illustrate motion in a static image using visual cues which do not represent a physical entity in the scene, yet are widely understood to convey motion. For example, consider the task of illustrating the desired movements for exercising, dancing, or a given sport technique. Traditional artists have developed techniques to specify desired movements precisely (technical illustrators) and suggest motion (cartoonists) in an image.
In this paper, we present an interactive system to synthesize a 2D image of an animated character by generating artist-inspired motion cues derived from 3D skeletal motion capture data. The primary cues include directed arrows, noise waves, and stroboscopic motion. First, the user decomposes the animation into short sequences containing individual motions which can be represented by visual cues. The system then allows the user to determine a suitable viewpoint for illustrating the movement, to select the proper level in the joint hierarchy, as well as to fine-tune various controls for the depiction of the cues themselves. While the system does provide adapted default values for each control, extracted from the motion capture data, it allows fine-tuning for greater expressiveness. Moreover, these cues are drawn in real time, and maintain a coherent display with changing viewpoints.
We demonstrate the benefit of our interactive system on various motion capture sequences.
