Three dimensional computer graphics with FORTRAN

Abstract

Generally, it is proposed in designing a graphics system that the display file segmentation enables a rapid picture generation in case of a picture modification. However, this proposal is valid only when the part of the picture is to be modified. It is true that in many cases only part of the picture changes dynamically, but it is also true that in many cases the modification of the picture is the change of the transformations. In this thesis, it is proposed that the transformations are considered as dynamic attributes of the segment. With this concept, the picture modication can be done without recompiling the display file in case of the transformations changes or with recompiling only the part of the display file, the segment, in case of other changes. A 3-d computer graphics system is designed with the above concept and is implemented on the NOVA 1200 as the basic system for a complete system, and further expanding of the system is suggested.
