Display the graphic structure of light source in the chosen view. We have three type of representation.
- SIMPLE : Only the light source is displayed.
- PARTIAL : The light source and the light space are displayed.
- COMPLETE : The same representation as PARTIAL. We can choose the "SAMELAST" as parameter of representation In this case the graphic structure representation will be the last displayed.
