NURBS (Non-Uniform Rational B-pline) the unified maths description that provided pair of standard analytic geometry and free curve, curved surface. It is in 3 times B batten curve is equational (2-8) in, through introducing an adjustable authority factor Wi (I=0, 1, ... , n) make aforementioned method more agile, control curvilinear appearance accurately thereby. Apical to giving three dimensional space to control Vi (I=0, 1, ... , n) reach Wi of its corresponding authority factor alignment, a K rank can be defined in three dimensional space (K-1) second in NURBS curve type, those who be NURBS curve base function, decide by undermentioned recurrence formula as similar as B batten curve, the curve that should make passes an end to control acme, but the curve two end points take K+1 each repeat node. NURBS method is in other of excel of a lot of respects is algorithmic, in the STEP standard lieutenant general that ISO promulgates consequently its regard product data as international standard of exchange.
