9 | class Presentation from Prs3d inherits Structure from Graphic3d |
10 | |
11 | ---Purpose: Defines a presentation object which can be displayed, |
12 | -- highlighted or erased. |
13 | -- The presentation object stores the results of the |
14 | -- presentation algorithms as defined in the StdPrs |
15 | -- classes and the Prs3d classes inheriting Prs3d_Root. |
16 | -- This presentation object is used to give display |
17 | -- attributes defined at this level to |
18 | -- ApplicationInteractiveServices classes at the level above. |
