Due to the existing algorithm of pencil drawing mainly focuses on automatically generated the images, and rendering with parameters is researched little. In view of this, it developed a colored pencil drawing rendering algorithm with multi-parameter in this paper. It presented an improved pencil texture generation algorithm by setting 6 parameters for pencil rendering, and using wavelet methods...

Introduction: One way to evaluate visual-spatial functions is to use line bisection test. With the advancement of information technology, this study attempted to design a line bisection test software and investigate its efficacy compared to the conventional paper-pencil form in schizophrenic patients. Method: The present study was a causal-comparative one and line bisection test software was de...

This paper proposes a new method for designing a developable surface by constructing a surface pencil passing through a given curve, which is quite in accord with the practice in industry design and manufacture. By utilizing the Frenet trihedron frame, we derive the necessary and sufficient conditions to construct a developable surface through a given curve. Considering the requirements in shoe...

Writing is a powerful skill that humans use on a daily basis to convey and capture information. J.J. Gibson pointed out that writing is a special form of tool use, which requires a special tool that has the ability to leave a trace on a surface: “A hand-held tool of enormous importance is one that, when applied to a surface, leaves traces and this affords tracemaking. The tool may be a stylus, ...
