Implementing Efficient Sketch Interface for Creating Vector Image

- Rough Sketch Style Method Using Pen-Input-Device -

Abstract

This paper presents several techniques usable for developing sketch interface to create line drawing image-like vector images. Recently, many researchers are studying on the design of user interface using pen-input-devices. We implemented experimental user interface by realizing the following functions: refining given rough strokes into lines considering the feature of hand drawing, generating plane graph presenting the planer structure of the lines by introducing new vertices to the intersection points of the lines, and erasing useless lines based on the plane graph efficiently. This approach taking into account the feature of analog devices and data structure of vector graphics enables us to create vector images efficiently.
