Member Function Documentation

Init()

template<class T>

void NCollection_Lerp< T >::Init ( const T &  theStart, const T &  theEnd  )

inline

Initialize values.

Interpolate() [1/3]

template<class T>

static T NCollection_Lerp< T >::Interpolate ( const T &  theStart, const T &  theEnd, double  theT  )

inlinestatic

Compute interpolated value between two values.

Parameters

theStart	first value
theEnd	second value
theT	normalized interpolation coefficient within [0, 1] range, with 0 pointing to theStart and 1 to theEnd.

Interpolate() [2/3]

template<class T>

void NCollection_Lerp< T >::Interpolate ( double  theT, T &  theResult  ) const

inline

Compute interpolated value between two values.

Parameters

theT	normalized interpolation coefficient within [0, 1] range, with 0 pointing to first value and 1 to the second value.
theResult	[out] interpolated value

Interpolate() [3/3]

template<>

void NCollection_Lerp< Handle< Graphic3d_Camera > >::Interpolate ( const double  theT, Handle< Graphic3d_Camera > &  theResult  ) const

inline

Linear interpolation tool for camera orientation and position. This tool interpolates camera parameters scale, eye, center, rotation (up and direction vectors) independently.
