B-Spline Software for the Sculpturing Robot Project

摘要

Routines for reading, writing, representing, sampling and taking derivatives forrational and non-rational B-spline curves and surfaces have been implemented. A routine that builds a B-spline object consisting of a set of B-spline surfaces from a STEP file with the entities CARTESIAN-POINT and B-SPLINE-SURFACE, has been implemented. An object approximator that approximates each surface of the B-spline object by a non-rational surface of degree 3, has been implemented. The software has been written in ADA.
