Detailed Description

template<>
class NCollection_Lerp< gp_Trsf >

Linear interpolation tool for transformation defined by gp_Trsf.

In general case, there is a no well-defined interpolation between arbitrary transformations, because desired transient values might vary depending on application needs.

This tool performs independent interpolation of three logical transformation parts - rotation (using gp_QuaternionNLerp), translation and scale factor. Result of such interpolation might be not what application expects, thus this tool might be considered for simple cases or for interpolating between small intervals.

Member Function Documentation

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

inline

Initialize values.

void NCollection_Lerp< gp_Trsf >::Interpolate ( double  theT, gp_Trsf &  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
