Abstract:
A problem of invariant on rotation curves, specified by the points, was investigated. Arc length was chosen as curve parameter. The algorithm for evaluation of arch length with 4th order of accuracy is proposed. Methods for calculating of others curve characteristics as tangent slope, curvature and derivative of curvature, were also offered. The common requirements for approximation supplying invariant on rotation approximation were investigated.
