Vector3  interpolate (Real t) const 
Returns an interpolated point based on a parametric value over the whole series. More...  
Vector3  interpolate (unsigned int fromIndex, Real t) const 
Interpolates a single segment of the spline given a parametric value. More...  
void  recalcTangents (void) 
Recalculates the tangents associated with this spline. More...  
void  setAutoCalculate (bool autoCalc)

void Ogre::SimpleSpline::addPoint  (  const Vector3 &  p  ) 
Adds a control point to the end of the spline.
const Vector3& Ogre::SimpleSpline::getPoint  (  unsigned short  index  )  const 
Gets the detail of one of the control points of the spline.
unsigned short Ogre::SimpleSpline::getNumPoints  (  void  )  const 
Gets the number of control points in the spline.
void Ogre::SimpleSpline::clear  (  void  ) 
Clears all the points in the spline.
void Ogre::SimpleSpline::updatePoint  (  unsigned short  index, 
const Vector3 &  value  
) 
Updates a single point in the spline.
Returns an interpolated point based on a parametric value over the whole series.
t  Parametric value. 
Interpolates a single segment of the spline given a parametric value.
fromIndex  The point index to treat as t=0. fromIndex + 1 is deemed to be t=1 
t  Parametric value 
void Ogre::SimpleSpline::setAutoCalculate  (  bool  autoCalc  ) 
Tells the spline whether it should automatically calculate tangents on demand as points are added.
autoCalc  If true, tangents are calculated for you whenever a point changes. If false, you must call reclacTangents to recalculate them when it best suits. 
void Ogre::SimpleSpline::recalcTangents  (  void  ) 
Recalculates the tangents associated with this spline.
