Function Documentation

XN_C_API XnDouble XN_C_DECL xnFPSCalc	(	XnFPSData *	pFPS,
		XnUInt32	nAverageOver = 3000,
		XnUInt64	nNow = 0
	)

This function calculates the average FPS over the last frames.

Parameters:

pFPS	[in] A pointer to an XnFPSData struct.
nAverageOver	[in] The number of milliseconds to average over.
nNow	[in] Optional. Current time. When not provided, function will take it itself.

XN_C_API XnStatus XN_C_DECL xnFPSFree

(

XnFPSData *

pFPS

)

This function frees the FPS calculator.

Parameters:

pFPS	[in] A pointer to an XnFPSData struct.

XN_C_API XnStatus XN_C_DECL xnFPSInit	(	XnFPSData *	pFPS,
		XnUInt32	nSamplesCount
	)

This function initializes the FPS calculator.

Parameters:

pFPS	[in] A pointer to an XnFPSData struct.
nSamplesCount	[in] The number of last frames to be kept.

XN_C_API XnStatus XN_C_DECL xnFPSMarkFrame	(	XnFPSData *	pFPS,
		XnUInt64	nNow = 0
	)

This function marks that another frame was processed.

Parameters:

pFPS	[in] A pointer to an XnFPSData struct.
nNow	[in] Optional. Current time. When not provided, function will take it itself.
