Detailed Description

This object contains methods for accessing point animation in a cache file.

The FBX SDK supports two point cache file formats :

eMaxPointCacheV2: the 3ds Max Point Cache 2 file format.
eMayaCache: the Maya Cache file format.

Accessing cache data using these formats differs significantly. To address this difference, two sets of methods have been created. Use the GetCacheFileFormat() function to determine which set of methods to use.

Examples:: ExportScene03/main.cxx, ViewScene/DrawScene.cxx, and ViewScene/SceneContext.cxx.

		FbxString &	pAbsoluteFileName
	)

Search for all occurrences

Get the nth cache file name.

Parameters:

pIndex	Index of the cache file to return; index is zero-based, and must be less than GetCacheDataFileCount().
pRelativeFileName	Return the point cache file name, relative to the FBX File name.
pAbsoluteFileName	Return the point cache file absolute path.

Returns:: true if successful, false otherwise. See the error management functions for error details.

bool EnableMultiChannelFetching ( bool pMultiChannelFetching )

Search for all occurrences

Enable multi-channel fetching.

Parameters:

pMultiChannelFetching Enable/disable multi-channel fetching. When multi-channel is enabled, any load of data on a channel at a specific time will pre-fetch data from all channels, for that specific time. This can reduce disk access, and increase performance (but requires more memory).

Returns:: true if successful, false otherwise. See the error management functions for error details.

bool GetNextTimeWithData	(	FbxTime	pCurTime,
		FbxTime &	pNextTime,
		int	pChannelIndex = `-1`
	)

Search for all occurrences

Get the next time where data is stored.

Parameters:

pCurTime	Current time; must be within the boundaries of the animation time.
pNextTime	Next time (filled if the function is successful).
pChannelIndex	The index of the animation channel, between 0 and GetChannelCount(). If pChannel is left at -1, get the next time for any channel.

Returns:: true if successful, false otherwise.

int GetDataCount ( int pChannelIndex )

Search for all occurrences

Get the number of data points the channel contains.

Parameters:

pChannelIndex The index of the animation channel, between 0 and GetChannelCount().

Returns:: The number of the channel's data points.

bool GetDataTime	(	int	pChannelIndex,
		unsigned int	pDataIndex,
		FbxTime &	pTime
	)

Search for all occurrences

Get the time of the specified data point.

Parameters:

pChannelIndex	The index of the animation channel, between 0 and GetChannelCount().
pDataIndex	Index of the data point.
pTime	Time of the data point (filled if the function is successful).

Returns:: true if successful, false otherwise.

bool OpenFileForWrite	(	double	pFrameStartOffset,
		double	pSamplingFrameRate,
		unsigned int	pSampleCount,
		unsigned int	pPointCount
	)

Search for all occurrences

Open a cache file for writing.

Parameters:

pFrameStartOffset	Start time of the animation, in frames.
pSamplingFrameRate	Number of frames per second.
pSampleCount	The number of samples to write to the file.
pPointCount	The number of points to write in the point cache file.

Returns:: true if successful, false otherwise. See the error management functions for error details.

unsigned int GetSampleCount ( )

Search for all occurrences

Get the number of frames of animation found in the point cache file.

Returns:: The number of frames of animation.

unsigned int GetPointCount ( )

Search for all occurrences

Get the number of points animated in the cache file.

Returns:: The number of points.

double GetFrameStartOffset ( )

Search for all occurrences

Get the start time of the animation.

Returns:: The start time of the animation, in frames.

bool Read	(	unsigned int	pFrameIndex,
		double *	pBuffer,
		unsigned int	pPointCount
	)

Search for all occurrences

Read a sample at a given frame index.

Parameters:

pFrameIndex	The index of the animation frame, between 0 and GetSampleCount().
pBuffer	The place where the point value will be copied. This buffer must be of size 3*pPointCount.
pPointCount	The number of points to read from the point cache file.

Returns:: true if successful, false otherwise. See the error management functions for error details.

bool Write	(	unsigned int	pFrameIndex,
		double *	pBuffer
	)

Search for all occurrences

Write a sample at a given frame index.

Parameters:

pFrameIndex	The index of the animation frame.
pBuffer	Point to the values to be copied. This buffer must be of size 3*pPointCount, as passed to the function OpenFileForWrite().

Returns:: true if successful, false otherwise. See the error management functions for error details.

Remarks:: Successive calls to Write() must use successive index.

bool ConvertFromPC2ToMC	(	EMCFileCount	pFileCount,
		double	pSamplingFrameRate
	)

Search for all occurrences

Create an MC cache file from an PC2 cache file.

Parameters:

pFileCount	Create one file for each frame of animation, or one file for all the frames.
pSamplingFrameRate	Number of frames per second used to re-sample the point animation.

Returns:: true if successful, false otherwise. See the error management functions for error details.

Remarks:: The created point cache file will be located in the _fpc folder associate with the FBX file.

Examples:: ViewScene/SceneContext.cxx.

bool ConvertFromMCToPC2	(	double	pSamplingFrameRate,
		unsigned int	pChannelIndex
	)

Search for all occurrences
