FT3D is a self-contained package of tools for three-dimensional Fourier analysis, written in the C language for Unix workstations. It can evaluate direct transforms of three-dimensional real functions, inverse transforms, auto- and cross-correlations and spectra. The library has been developed to support three-dimensional reconstructions of biological structures from projections obtained in the electron microscope. This paper discusses some features of the library, which has been implemented in such a way as to profit from the resources of modern workstations. A table of elapsed times for jobs of different dimensions with different RAM buffers is reported for the particular hardware used in the authors' laboratory.
FT3D是一个用于三维傅里叶分析的独立工具包，用C语言编写，适用于Unix工作站。它可以评估三维实函数的直接变换、逆变换、自相关和互相关以及频谱。该库的开发是为了支持从电子显微镜获得的投影进行生物结构的三维重建。本文讨论了该库的一些特性，其实现方式利用了现代工作站的资源。针对作者实验室使用的特定硬件，报告了不同维度的作业在不同随机存取存储器缓冲区下的运行时间表。
