how can we write custom displaymode.
i need a dispaly mode which is a mix of shaded mode and wireframe like we see in cad exchanger..
I need to see the flat lines also when we are showing shaded mode.
Can anybody help me
Thanks in advance |

The trick is to derive your own class from AIS_Shape, and override its Compute( const Handle(PrsMgr_PresentationManager3d)& aPresentationManager, const Handle(Prs3d_Presentation)& aPresentation, const Standard_Integer aMode ) method.
Within your Compute method make the following two calls:
// Draw the wireframe
StdPrs_WFDeflectionShape::Add(aPresentation,Shape(),myDrawer);
// Draw the solid surfaces
StdPrs_ShadedShape::Add(aPresentation,Shape(),Attributes());

Dear Forum supervisor,
wouldn't it be good to add this combination of wireframe and shaded mode as a separate display mode to AIS_Shape?
Then it wouldn't be necessary to derive an own subclass from AIS_Shape for this purpose. As this mode is available in many CAD applications today, many OCC-based applications would benefit from it.
In our application we simulated this mode until now by using shaded mode together with colored highlighting.
Regards,
Timo

I added a feature request in the bug tracker:
http://tracker.dev.opencascade.org/view.php?id=23359
Unfortunately, I'm not very familiar with the internals of AIS_Shape. Maybe someone else did already the corresponding modifications and would be ready to contribute the code?
Regards,

The change introduced in branch 23407 does the job!
Very nice!
