APPENDIX A
First, the appendix presents an overview of the Seplib objects SepInput,
SepOutput which represents respectively an input or ouput
header file and data file. The classes
SepInfo, SepAxis which describe the structure of the data are
also presented.
Second the graphic objects derived from the GSObject or GSNPtObject
such as GSPlane, GSMultiLine, GSBSplines are described.
Third we present some InterViews interactor View, GraPanel, Iaxis
used into the examples.
Then we describe in one final table the interface of two rubberbands used
into the Overlay program and presented in the Figure ,
respectively RubberHyperbola and RubberParabola.
