The HLLSRF Hull Representation System

Abstract

HLLSRF is a system for representing ship hulls for use in computer programs. In particular, it has been designed to be used with programs which calculate the hydrodynamic properties of ship hulls. HLLSRF uses a parametric tensor product B-spline representation of the hull in which one of the parameters is the station number. Complex hull shapes may be generated by allowing non-rectangular domains in parameter space. Variations of existing hulls can be represented by specifying how they differ from their parents. This report describes the HLLSRF representation scheme itself and programs for generating hull representations from offset data. Keywords: Canada, French language.
