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.

该研究项目的目的是开发一种通用软件，以便在图形显示器或 PostScript 打印机等上轻松图形显示科学计算结果，如函数图、梯度向量场、等高线图、3D 图形等。除本系统与XWindow系统的几个接口子程序采用C语言编写外，其余程序均采用FORTRAN77编写。还包括运行在XWindow系统上的GKS和CALCOMP的图形内核子程序。我们按照最初的计划开发了该软件。完成了XWindow系统上的GKS和CALCOMP图形内核子程序以及函数图、梯度向量场、等高线图、3D图形显示的各种子程序。除此之外，还利用Tcl/Tk完成了本系统与用户之间的接口程序，以方便系统的使用。子例程库还包括计算适合每个显示器的坐标系统的子例程，以及基于矩形网络或三角形网络等上的数值数据计算 3D 图形的子例程。用户可以轻松更改位置、大小和视点图形显示屏上的图形。该系统以首席研究员的名字命名为 moriplot。
