NurbsCurve
Overview
NurbsCurve is a class in Aspose.3D FOSS for Java.
Inherits from: Curve.
NURBS curve is a curve represented by NURBS(Non-uniform rational basis spline), A NURBS curve is defined by its getOrder(), a set of weighted Geometry.getControlPoints() and a getKnotVectors() The w
This class provides 38 methods for working with NurbsCurve objects in Java programs.
Available methods include: A3DObject, Curve, Entity, NurbsCurve, SceneObject, evaluate, evaluateAt, findProperty, getBoundingBox, getColor, getControlPoints, getCurveType, and 24 additional methods.
All public members are accessible to any Java application after installing the Aspose.3D FOSS for Java package.
Properties: boundingBox, color, controlPoints, curveType, degree, dimension, and 10 more.
