Abstract
This report describes the method for generating a developable surface between two space curves and obtaining a development of it.
On ruled surfaces, the existence of a tangent plane is equivalent to its being a developable surface. Therefore, the generators are determined so as to be a developable surface between two space curves, and a development is created using a generalized unfolding formula for the developable surface generated in this way.
In this method, it is possible to obtain a development uniformly without considering the types of developable surfaces. It is theoretically impossible to draw a development of a surface other than a developable surface, because the surface generated between two space curves is guaranteed to be a developable surface.
If two space curves cannot generate a developable surface, a development cannot be obtained. However, the existence of a tangent plane can be easily determined because it can be imaged without complicated calculations.
