|Target Version||[OCCT] 6.5.4||Fixed in Version|
|Summary||0023359: new display mode: "wireframe and shaded"|
|Description||Wouldn't it be good to add a combination of wireframe and shaded mode (see CAD Exchanger) as a separate display mode to AIS_Shape?|
It was proposed on the forum: http://www.opencascade.org/org/forum/thread_22134/?forum=3 [^]
Unitl now, it was necessary to derive an own subclass from AIS_Shape as proposed by Eric Thompson:
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
// Draw the solid surfaces
If this feature were added to standard OCC, it wouldn't be necessary to derive an own subclass for this purpose. As this display 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.

That is correct, #23407 provides the desired behavior (see related changeset)
Could you please check the solution for #23407?
For now, I just reviewed the code.
My original idea was to add this behavior as an additional display mode to the AIS_DisplayMode enumeration and make it usable for AIS_Shape. Would this require still much work? Probably, then it would be most easy to use.
But accessing this behavior via the AIS_Drawer is also OK and it is more flexible as you can set the color and the line type.
However, a separate standard display mode would be beneficial in my opinion.
Would it be OK, if I do the final testing when a beta release for 6.6.0 is available as I'm not using GIT at the moment?
I believe the new AIS_Drawer settings are recognized at StdPrs_ShadedShape level so this change affects both XCAFPrs and AIS packages that use this tool class.
As I do not see any obvious benefits of having additional display mode (while obviously it is less efficient with respect to memory usage), I suggest we keep it as is for 6.5.4 release and collect the feedback to decide if it is OK or not.
Please close this issue as duplicate of #23407.
From my point of view it is better not to add an additional display mode as this might require restructuring the application GUI etc.
Just my 50 cent...
