本文提出了一种基于物理的火灾模拟中单个火焰的艺术方向的新方法。火，由于其温暖的色彩和不断的运动，往往成为主要的吸引力，观众的眼睛在一个场景。因此，能够控制火模拟，以获得所需的外观或形状是至关重要的，如果模拟是用来创建火的效果。我们的技术在一个精细的水平上提供了对这种混乱的自然现象的控制，使艺术家能够为火焰添加字符并创建高度风格化的视觉效果。消防系统本身是一个完全基于物理的双气体系统，火焰沿着燃烧产生的对流平流。我们的方法使用艺术家绘制的一组导入曲线，提供对这些对流的艺术控制。详细介绍了该消防系统的实现和性能，并给出了控制方法。使用我们的系统渲染的高度风格化火焰艺术品的例子说明了该技术。
This paper presents a new approach to the art direction of individual flames in a physically based fire simulation. Fire, due to its warm colors and constant movement, often becomes the main attraction to the viewer's eye in a scene. Therefore, being able to control afire simulation to obtain a desired look or shape is crucial if simulation is to be used to create afire effect. Our technique provides control over this chaotic natural phenomenon at a fine level, enabling the artist to add character to flames and create highly stylized visuals. The fire system itself is a fully physics-based two-gas system, where flames are advected along convection currents generated by combustion. Our method provides artistic control of these convection currents, using a set of imported curves drawn by an artist. A full description of the implementation and performance of the fire system, and our control method is presented. The technique is illustrated with examples of highly stylized flame artwork rendered using our system.
