Dynamic Curve Simulator

Shin Yoshizawa

This interactive program visualizes dynamic properties of planar curves including tangent vectors, normal vectors, curvature normals, osculating circles, evolute, offset curves, families and envelopes, caustics, orthotomic curve, orthotomic normals, family of orthotomic normals (caustics), family of curve evolutions (curvature flow, laplacian flow and contour map), Voronoi diagram, and inner and outer skeletons (medial axis, bi-tangent circle and voronoi).

This research is collaborated with Prof. Dr. A. G. Belyaev. The paper was published in Proc. International Conference on Multimedia Modeling, pp. 469-489, November 13-15, 2000, Nagano, Japan.
