Log-Aesthetic Magnetic Curves and Their Application for CAD Systems

Abstract EN

Curves are the building blocks of shapes and designs in computer aided geometric design (CAGD).

It is important to ensure these curves are both visually and geometrically aesthetic to meet the high aesthetic need for successful product marketing.

Recently, magnetic curves that have been proposed for computer graphics purposes are a particle tracing technique that generates a wide variety of curves and spirals under the influence of a magnetic field.

The contributions of this paper are threefold, where the first part reformulates magnetic curves in the form of log-aesthetic curve (LAC) denoting it as log-aesthetic magnetic curves (LMC) and log-aesthetic magnetic space curves (LMSC), the second part elucidates vital properties of LMCs, and the final part proposes G2 LMC design for CAD applications.

The final section shows two examples of LMC surface generation along with its zebra maps.

LMC holds great potential in overcoming the weaknesses found in current interactive LAC mechanism where matching a single segment with G2 Hermite data is still a cumbersome task.
