Holographic three-dimensional display is an important display technique because it can provide all depth information of a real or virtual scene without any special eyewear. In recent years, with the development of computer and optoelectronic technology, computer-generated holograms have attracted extensive attention and developed as the most promising method to realize holographic display. However, some bottlenecks still restrict the development of computer-generated holograms, such as heavy computation burden, low image quality, and the complicated system of color holographic display. To overcome these problems, numerous algorithms have been investigated with the aim of color dynamic holographic three-dimensional display. In this review, we will explain the essence of various computer-generated hologram algorithms and provide some insights for future research.

全息三维显示是一种重要的显示技术，因为它可以提供真实或虚拟场景的所有深度信息，而无需任何特殊的眼镜。近年来，随着计算机和光电技术的发展，计算机生成的全息图引起了广泛的关注，并发展成为最有前途的全息显示方法。然而，计算机生成全息图的发展仍然存在计算量大、图像质量低、彩色全息显示系统复杂等瓶颈。为了克服这些问题，已经研究了许多以彩色动态全息三维显示为目标的算法。在这篇评论中，
