| Research Abstract |
An 3D solid modeling software has been developed for the education of the descriptive geometry and computer graphics. The boundary representation and the winged-edges method have been adopted as a description method of solid model. The developed solid modeler can create a 3D solid model by executing the command lines of text format. Combining more than 13 kinds of primitive models, the solid model is constructed. The developed software has several kinds of display modes more than 150,such as the edge-type, the surface-type, the perspective and parallel views, three faces and so on. The fucntions of the development of 3D-model onto sheet and the modeling with the mathematical functions were added on the software.
The practice of descriptive geometry with the software had been carried out in Tokyo Denki University and two elementary schools. The students were interested in the geometry and enjoyed the modeling of 3D structures.
