The purpose of this research project is to develop a general purpose software for easy graphical display of the result of scientific computation like function graphs, gradient vector fields, contour maps, 3D figures, on a graphic display or on a PostScript printer, etc. Source programs are written in FORTRAN77 except several interface subroutines between the present system and the XWindow system which are written in C language. Graphic kernel subroutines of GKS and CALCOMP working on the XWindow system are also included.We developed the software as initially planned. Graphic kernel subroutines of GKS and CALCOMP on the XWindow system and various subroutines for display of function graphs, gradient vector fields, contour maps, 3D figures are completed. In addition to that, an interface program between the present system and the user using Tcl/Tk is also completed for easy use of the system. The subroutine library also includes subroutines that compute a coodinate system appropriate to each display and that compute a 3D figure based on numerical data over a rectangular network or over a triangular network, etc. The user can easily cange the location, the size and the viewpoint of the figure on the graphic display. The system is called moriplot after the name of the head investigator.

本研究项目的目的是开发一个通用的软件，方便图形显示的科学计算的结果，如函数图，梯度矢量场，等值线图，三维图形，在图形显示器上或打印机上，等等。源程序用FORTRAN 77编写，除了本系统和XWindow系统之间的几个接口子程序是用C语言编写的。本文还介绍了在XWindow系统上运行的GKS和CALCOMP的图形核心子程序。完成了XWindow系统下GKS和CALCOMP的图形核心子程序以及函数图、梯度矢量场、等值线图、三维图形等的显示子程序。此外，为了方便用户使用本系统，还利用Tcl/Tk语言编写了本系统与用户的接口程序。该子程序库还包括计算适合于每个显示器的坐标系和基于矩形网络或三角形网络等上的数值数据计算3D图形的子程序。用户可以容易地改变图形显示器上的图形的位置、大小和视点。该系统被称为moriplot后，首席调查员的名字。
