Class Description

A Non-Uniform Rational B-Spline (NURBS) curve is a type of parametric geometry.

A NURBS curve is defined by the order, form, knot vector and control points.

Let M be the order of the curve. Let N be the number of control points of the curve.

The form of the curve can be open, closed or periodic. A curve with end points that do not meet is defined as an open curve. The number of knots in an open curve is defined as N+(M+1).

A closed curve simply has its last control point equal to its first control point. Note that this does not imply tangent continuity at the end point. The curve may have a kink at this point. In FBX the last control point is not specified by the user in the InitControlPoints() method. For example, if there are to be 10 control points in total, and the curve is to be closed, than only 9 control points need to be passed into the InitControlPoints() method. The last control point is implied to be equal to the first control point. Thus N represents the number of unique CVs.

A periodic curve has its last M control points equal to its first M control points. A periodic curve is tangent continuous at the ends. Similar to a closed curve, when creating a periodic curve, only the unique control points need to be set. For example a periodic curve of order 3 with 10 control points requires only 7 CVs to be specified in the InitControlPoints() method. The last 3 CVs, which are the same as the first 3, are not included.

The calculation of the number of knots in closed and periodic curves is more complex. Since we have excluded one CV in N in a closed curve, the number of knots is N+(M+1)+1. Similarly, we excluded M CVs in periodic curves so the number of knots is N+(M+1)+M.

Note that FBX stores one extra knot at the beginning and and end of the knot vector, compared to some other graphics applications such as Maya. The two knots are not used in calculation, but they are included so that no data is lost when converting from file formats that do store the extra knots.

void InitControlPoints	(	int	pCount,
		EType	pVType
	)

Allocates memory space for the control points array as well as for the knot vector.

Parameters

pCount	Number of control points.
pVType	NURBS type.

Remarks

This function should always be called after FbxNurbsCurve::SetOrder().

double* GetKnotVector ( ) const

inline

Returns the knot vector.

Returns

Pointer to the knots array.

Definition at line 101 of file fbxnurbscurve.h.

{ return mKnotVector; }

int GetKnotCount

(

)

const

Returns the number of elements in the knot vector.

Returns

The number of knots.

void SetOrder ( int  pOrder )

inline

Sets the order of the curve.

Parameters

pOrder

The curve order.

Remarks

The curve order must be set before InitControlPoints() is called.

{ mOrder = pOrder; }

int GetOrder ( ) const

inline

Returns the NURBS curve order.

Returns

The NURBS curve order.

{ mStep = pStep; }

int GetStep ( ) const

inline

Returns the NURBS curve step.

Returns

The NURBS curve step.

const

This function determines if this NURBS curve is a Bezier curve.

Bezier curves are a special case of NURBS curve.

Evaluate the point on the curve.

Save the result as a point array. Meanwhile, return the length of the point array.

Parameters

pPointArray	Save the evaluate result as a point array.
pStep	The evaluation frequency between two neighbor knots. Its default value is 16, which is same as Maya.

Returns

The length of the point array.

FbxLine* TessellateCurve

(

int

pStep = 16
