Package Basic.NURBS

package Basic.NURBS

Non-Uniform Rational B-Spline (NURBS) provide a parametric mathematical model for generating and representing smooth curves and surfaces.

Non-Uniform Rational B-Spline (NURBS) provide a convenient and efficient manner to generate curved lines and surfaces which can be smooth at any viewing distance. Since these surfaces are generated parametrically, only a small amount of data need be provided for describing complex surfaces. These examples support the X3D NURBS component.

These capabilities hold significant potential value for use by the Computer Aided Design (CAD) and Medical working groups.

This X3D Basic: NURBS examples archive is online.

The X3D Java Scene Access Interface (x3djsail) package provides concrete classes for each X3D node and statement.
