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.
