X3D Reference

NurbsSurfaceInterpolator

NurbsSurfaceInterpolator

NurbsSurfaceInterpolator describes a 3D NURBS curve and outputs interpolated position and normal values.

The NurbsSurfaceInterpolator node belongs to the NURBS component and its container field is children. It is available since X3D version 3.0 or later.

Hierarchy

Fields

SFNode [in, out] metadata NULL [X3DMetadataObject]

Metadata are not part of the X3D world and not interpreted by the X3D browser, but they can be accessed via the ECMAScript interface.

SFVec2f [in] set_fraction (-∞,∞)

Setting fraction in range [0,1] selects input key for corresponding keyValue output, computing a 3D position on the curve.

SFNode [in, out] controlPoint NULL [X3DCoordinateNode]

Input/Output field controlPoint.

MFDouble [in, out] weight [ ] (-∞,∞)

Output values for linear interpolation, each corresponding to knots.

Hint

Number of weights must match number of knots!

SFVec3f [out] position_changed

Linearly interpolated output value determined by current key time and corresponding keyValue pair.

SFVec3f [out] normal_changed

Linearly interpolated output value determined by current key time and corresponding keyValue pair.

SFInt32 [ ] uDimension [0,∞)

Number of control points in u dimension.

MFDouble [ ] uKnot [ ] (-∞,∞)

Knot vector, where size = number of control points + order of curve.

SFInt32 [ ] uOrder 3 [2,∞)

Define order of surface by polynomials of degree = order-1.

SFInt32 [ ] vDimension [0,∞)

Number of control points in v dimension.

MFDouble [ ] vKnot [ ] (-∞,∞)

Knot vector, where size = number of control points + order of curve.

SFInt32 [ ] vOrder 3 [2,∞)

Define order of surface by polynomials of degree = order-1.

Description

Hint

  • The SFNode controlPoints field can contain a single Coordinate or CoordinateDouble node.
