The standard cube mapping technique implemented in graphics pipelines, while useful in many scenarios, has significant shortcomings for important application areas in interactive computer graphics, e.g., dynamic environment mapping, omnidirectional shadow maps, or planetary-scale terrain rendering. Many alternative mapping methods have been proposed over the years with the purpose of reducing area and/or angular distortions. In this paper, we give an overview of methods suitable for interactive applications and analyze their properties. Furthermore, we evaluate a set of additional transformation functions and identify a simple new method with favorable distortion properties.

交互式计算机图形中立方体映射方法的调查

在图形管道中实现的标准立方体映射技术虽然在许多场景中很有用，但对于交互式计算机图形中的重要应用领域，例如动态环境映射、全向阴影映射或行星尺度地形渲染，存在明显的缺点。多年来，为了减少面积和/或角度失真，已经提出了许多替代映射方法。在本文中，我们概述了适用于交互式应用程序的方法并分析了它们的特性。此外，我们评估了一组额外的变换函数，并确定了一种具有良好失真特性的简单新方法。
