Detailed Description

Represents a NURBS spline.

This is a typical NURBS spline. It uses a list of FMVector3 for its control vertices, along with a list of float to represent each vertex weight. A knot vector (uniform or not, clamped or not), together with a degree, complete the specification.

Member Function Documentation

bool FCDNURBSSpline::AddCV (  const FMVector3 &  cv, float  weight )

Add a control vertex as a 3D position and a weight attribute specific to this CV. Parameters: cv  The 3D position. weight  The weight attribute.

void FCDNURBSSpline::AddKnot (  float  knot  )  [inline]

Add a knot to this NURB. Parameters: knot  The knot value.

virtual FCDSpline* FCDNURBSSpline::Clone (  FCDSpline *  clone  )  const [virtual]

[INTERNAL] Copies the spline into a clone. The clone may reside in another document. Parameters: clone  The empty clone. This pointer cannot be NULL. Returns: The clone. Reimplemented from FCDSpline.

uint32 FCDNURBSSpline::GetDegree (   )  const [inline]

Get the degree for this NURBS. Returns: The degree.

float* FCDNURBSSpline::GetKnot (  size_t  index  )  [inline]

Retrieves a reference to the knot specified by the index. Parameters: index  The index. Returns: The address of the knot value, NULL if index is invalid.

size_t FCDNURBSSpline::GetKnotCount (   )  const [inline]

Retrieves the knot count in this NURB. Returns: The knot count.

FloatList& FCDNURBSSpline::GetKnots (   )  [inline]

Retrieves a const reference to the knot list. Returns: The knots' const reference.

virtual FUDaeSplineType::Type FCDNURBSSpline::GetSplineType (   )  const [inline, virtual]

FCDSpline method implementation. Returns: The NURBS spline type. Implements FCDSpline.

float* FCDNURBSSpline::GetWeight (  size_t  index  )  [inline]

Retrieves a reference to the weight specified by the index. Parameters: index  The index. Returns: The address of the weight value, NULL if index is invalid.

FloatList& FCDNURBSSpline::GetWeights (   )  [inline]

Retrieves a const reference to the weight list. Returns: The weights' const reference.

virtual bool FCDNURBSSpline::IsValid (   )  const [virtual]

Determines if the spline is valid. Returns: True is the spline is valid, false otherwise.

void FCDNURBSSpline::SetDegree (  uint32  deg  )  [inline]

Set the degree for this NURBS. Parameters: deg  The wanted degree.
