vec_t CTransferFunctionElem::getAbsorptivity (  void   )  const [inline]
 

Returns:
basic absorptivity for this transfer function element the absorptivity describes how much of the light is absorbed on a 1/128 of the x length of the volume, also regarding the slice thickness. if the absorptivity is 'a', then exp(-a) will shine thru such a segment.
