| Outline of Final Research Achievements |
In the design of aesthetic surface, it is a common practice to use highly aesthetic curves to make aesthetic surface. This research proposes quadratic log-aesthetic curves that are curves whose logarithmic curvature graphs are quadratic, clarifies the fundamental characteristics, and confirms that the curves can be generated in real time by implementing the algorithm. This theory can immediately be used for logarithmic torsion graphs. To generate curves with curvature control, the research on curve generation by specifying curvature plot in terms of explicit Bezier curves is also conducted.
