void TwoDStatsGeneration::calculatePlayerImpactPtsFromIndices	(	std::vector< std::vector< cv::Point3f > > &	_inputPlayerBallPts,
		std::vector< std::vector< int > > &	_playerDeepestPtIndices,
		std::vector< cv::Point > &	o_playerImpactPtsAllRallies
	)

calculates the actual player impact points from the available data and the indices this will be called by the player class whenever it needs data into impact points vector

Parameters:

[in]	_inputPlayerBallPts	represents tracked pts
[in]	_playerDeepestPtIndices	represents depth look up pts
[out]	o_playerImpactPtsAllRallies	represents depth pts

		std::vector< cv::Point > &	_playerImpactPtsAllRallies,
		int	_whichQuadrant,
		std::vector< cv::Point > &	o_specificQuadPts,
		float &	o_percentage
	)

given sets of dimensions of the field of play, this would fill up a specific percentage value representing the the corresponding field of play percentage so one set of dimension, returning one percentage value

Parameters:

[in]	_widthBounds	represents width of TT table
[in]	_heightBounds	represents height of TT table
[in]	_whichQuadrant	represents court sides
[out]	o_specificQuadPts	represents retrieved quad specific pts
[out]	o_percentage	represents retrieved quad specific percentages
