Abstract
Fixing our eyes on the personal usage of the recent micro-computers, which have been remarkably developed one of these days, some applications on the Descriptive Geometry are presented in this paper. For example, intersecting bodies are colorfully displayed on the computer image which shows their shade and shadow by using the ray tracing method for the solid bodies. The results show that the usage of micro-computer is effective to solve some problems on Descriptive Geometry and it is a good tool to understand the shapes and construction of 3-D objects.
