CREST-ED3GE: Evolving Design and Discrete Differential GEometry
- towards Mathematics Aided Geometric Design

We originate a novel geometry of discrete surfaces having the surfaces with good properties, such as developable surfaces, as the shape elements, incorporate the theory of aesthetic shapes and construct the technique of structural analysis/optimization on it. Under this framework, we develop an innovative software platform that enables structural design with high efficiency and low cost, endowed with beauty and artisticity, and guaranteeing security and safety. We integrate the knowledge in various areas of design to the geometry of shapes by the power of mathematics, and provide it as a basis of the regeneration of Japanese manufacturing which creates precise and beautiful products but with currently high cost.

Abbreviated Title and Logo

EDDDGE

ED3GE, the abbreviated title of the project "Evolving Design and Discrete Differential Geometry ? towards Mathematics Aided Geometric Design," has the following meanings:

  • The power that enables preceding, advantage, competitiveness, superiority, predominance.
  • "Edge" as the basic element of the discrete differential geometry which discretizes the surfaces by polygons.
  • "Edge" of a sword. The log-aesthetic curves, a basic element of this research project, describe the shape of the edge of Japanese swords which is an essence of Japanese beauty.

The logo is designed motivated by a Japanese sword because of the above meanings. In particular, the curves of the edge of the sword and the object overlapping letters are made of log-aesthetic curves. The log-aesthetic curve is a family of plane curves introduced by the researchers of industrial design by extracting the common property from thousands of curves that car designers regard as aesthetic. This family consists of the curves whose power of curvature radii are linear in the arc length. It is shown under the framework of the "similarity geometry," which is different from the ordinary Euclidean geometry, that the log-aesthetic curves have the common properties with the famous family of plane curves called "Euler's elastic curves" in the Euclidean geometry. In this manner, the log-aesthetic curves are known to be the family of curves with good mathematical properties.
