void TransferFunction::CalcTF (  int  oldK, int  newK, COLORREF  oldV, COLORREF  newV, int  oldOp, int  newOp )  [private]

interpolates colors and opacities between to specified points Parameters: oldK  newK  oldV  newV  oldOp  newOp

void TransferFunction::CreateTransferFunction (  std::map< int, COLORREF >  m, std::map< int, int >  mOp )

creates a transfer function of given input (entries with specified intensity value, color and opacity) Parameters: std::map<int  m  std::map<int  mOp

void TransferFunction::CreateWindowingFunction (  int  min, int  max )
