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.
