New algorithmic and hardware developments over the past two decades have enabled interactive ray tracing of small to modest sized scenes, and are finding growing popularity in scientific visualization and games. However, interactive ray tracing has not been as widely explored in the context of production film rendering, where challenges due to the complexity of the models and, from a practical standpoint, their unavailability to the wider research community, have posed significant challenges. The recent release of the Disney Moana Island Scene has made one such model available to the community for experimentation. In this paper, we detail the challenges posed by this scene to an interactive ray tracer, and the solutions we have employed and developed to enable interactive path tracing of the scene with full geometric and shading detail, with the goal of providing insight and guidance to other researchers.

消化大象——莫阿那岛场景互动制作质量路径追踪的经验

过去二十年中新算法和硬件的发展使小到中等大小场景的交互式光线追踪成为可能，并且在科学可视化和游戏中越来越受欢迎。然而，交互式光线追踪并没有在制作电影渲染的背景下得到广泛的探索，由于模型的复杂性以及从实践的角度来看，它们对更广泛的研究社区不可用，这带来了重大挑战。最近发布的 Disney Moana Island Scene 已经为社区提供了一种这样的模型进行实验。在本文中，我们详细介绍了该场景对交互式光线追踪器带来的挑战，以及我们采用和开发的解决方案，以实现具有完整几何和阴影细节的场景交互式路径追踪，
