在电影中渲染头发是一项重要且具有挑战性的任务。尽管对基于物理的头发渲染进行了大量研究，但目前很难从这项工作中受益，因为基于物理的着色模型不提供艺术家友好的控件。因此，到目前为止，许多生产工作都使用了更容易控制的专用着色器，但通常缺乏真实的头发中所见的丰富性。我们表明，基于物理的着色模型无法提供直观的艺术家控制，我们介绍了一种新的方法，从现有的基于物理的模型创建一个艺术导向的头发着色模型。通过一个非正式的用户研究，我们表明，该系统是更容易使用现有的系统相比。我们的着色器已被集成到沃尔特迪士尼动画工作室的生产流水线中，并被用于即将上映的动画长片《魔发奇缘》的制作。
Rendering hair in motion pictures is an important and challenging task. Despite much research on physically based hair rendering, it is currently difficult to benefit from this work because physically based shading models do not offer artist friendly controls. As a consequence much production work so far has used ad hoc shaders that are easier to control, but often lack the richness seen in real hair. We show that physically based shading models fail to provide intuitive artist controls and we introduce a novel approach for creating an art-directable hair shading model from existing physically based models. Through an informal user study we show that this system is easier to use compared to existing systems. Our shader has been integrated into the production pipeline at the Walt Disney Animation Studios and is being used in the production of the upcoming animated feature film Tangled.
