我们提出了一种生成艺术可引导的体积效果的方法，范围从物理精确到非物理结果。我们的系统通过使用直观的照明基元，并将该基元的建模和着色解耦，模仿经验丰富的艺术家思考体积效果的方式。为了实现这一目标，我们推广了基于物理的光子束方法，以允许任意编程的模拟和着色阶段。这为艺术家提供了一个直观的设计空间，可以快速探索各种基于物理的以及看似合理但夸张的体积效果。我们将我们的方法集成到现实世界的生产流程中，并将体积效果与表面着色相结合。
We present a method for generating art-directable volumetric effects, ranging from physically-accurate to non-physical results. Our system mimics the way experienced artists think about volumetric effects by using an intuitive lighting primitive, and decoupling the modeling and shading of this primitive. To accomplish this, we generalize the physically-based photon beams method to allow arbitrarily programmable simulation and shading phases. This provides an intuitive design space for artists to rapidly explore a wide range of physically-based as well as plausible, but exaggerated, volumetric effects. We integrate our approach into a real-world production pipeline and couple our volumetric effects to surface shading.
