Temporal Antialiasing (TAA), formally defined as temporally‐amortized supersampling, is the most widely used antialiasing technique in today's real‐time renderers and game engines. This survey provides a systematic overview of this technique. We first review the history of TAA, its development path and related work. We then identify the two main sub‐components of TAA, sample accumulation and history validation, and discuss algorithmic and implementation options. As temporal upsampling is becoming increasingly relevant to today's game engines, we propose an extension of our TAA formulation to cover a variety of temporal upsampling techniques. Despite the popularity of TAA, there are still significant unresolved technical challenges that affect image quality in many scenarios. We provide an in‐depth analysis of these challenges, and review existing techniques for improvements. Finally, we summarize popular algorithms and topics that are closely related to TAA. We believe the rapid advances in those areas may either benefit from or feedback into TAA research and development.

时间抗锯齿技术综述

时间抗锯齿 (TAA)，正式定义为时间摊销超级采样，是当今实时渲染器和游戏引擎中使用最广泛的抗锯齿技术。本调查提供了该技术的系统概述。我们首先回顾一下TAA的历史、发展路径和相关工作。然后我们确定 TAA 的两个主要子组件，样本积累和历史验证，并讨论算法和实现选项。随着时间上采样与当今的游戏引擎越来越相关，我们建议扩展我们的 TAA 公式以涵盖各种时间上采样技术。尽管 TAA 很受欢迎，但在许多场景中仍然存在影响图像质量的重大未解决的技术挑战。我们对这些挑战进行了深入分析，并审查现有技术以进行改进。最后，我们总结了与 TAA 密切相关的流行算法和主题。我们相信这些领域的快速进步可能会受益于或反馈到 TAA 的研究和开发中。
