Detailed Description

Alpha entries represent linearly interpolated transparency values along the isovalue scale.

Alpha is in the range [ 0...1 ] where 1 signifies entirely opaque ( which makes it more an opacity value instead of alpha, but I use the commonly used language here )

◆ AlphaEntry()

WTransferFunction::AlphaEntry::AlphaEntry	(	double	iso,
		double	alpha
	)

inline

default constructor

Parameters

iso	the isovalue
alpha	the alpha at the isovalue in the range from 0 = transparent to 1 = opaque
