Detailed Description

More dimensional vectors are split into components. E.g. a 3D velocity vector gets stored in three FlowChannels. A FlowChannel stores data only from one time step, it is not aware of any time related information.

Member Function Documentation

void FlowChannel::copyValues	(	float *	rawdata,
		int	vtxSize,
		int	offset
	)

takes an array containing all attributes for a vertex and copies the j-th attribute to this channel

This methos is used by the loading of data sets.

Parameters:

	rawdata	data gained directly from the file, without any processing. It contains all channels for all cells. Please note, there is no time information considered here.
	vtxSize	number of channels per cell (incl. velocity vector size)
	offset	offset of the parameter loaded into this channel
