Detailed Description

template<typename T>
class vl::CatmullRomInterpolator< T >

The LinearInterpolator class is a template class that implements Catmull-Rom spline interpolation.

Catmull-Rom spline interpolation allows smoother interpolations than simple linear interpolation, is thus indicated for example when you want to smoothly interpolate from one position to another or from one color to another.

Member Function Documentation

template<typename T >

void vl::CatmullRomInterpolator< T >::setupEndPoints

(

bool

is_loop )

[inline]

Call this function after having specified the control points if you want to automatically generate the start/end control points.

template<typename T >

T vl::CatmullRomInterpolator< T >::computePoint

(

float

t )

const [inline]

Samples the Catmull-Rom spline at the given point. The t parameter must be in the range 0.0 ... 1.0 included.

template<typename T >

void vl::CatmullRomInterpolator< T >::setPath

(

const std::vector< T > &

path )

[inline]

The control points defining the Catmull-Rom spline.

Because of the Catmull-Rom formula the interpolated path must start and end with an extra control point (one on each side) and cannot have less than 4 control points. You can also automatically generate such extra control points by calling the setupEndPoints() method.

template<typename T >

const std::vector<T>& vl::CatmullRomInterpolator< T >::path

const [inline]

The control points defining the Catmull-Rom spline.

template<typename T >

The control points defining the Catmull-Rom spline.
