Issue with 6.2 in back of 6.1

Insert a rectangle (or any other object) and use "Toggle Extrusion" from the drawing toolbar (View > Toolbars > Drawing). That results in a 3D-like object for 6.1 but not 6.2. Happens on Windows with Beta and on Linux with master from latest sources, and for Writer as well as Draw.

Comment 3 Armin Le Grand (allotropia) 2018-07-12 09:01:45 UTC
Strange - normal 3D (Draw objects, Chart, ...) works well.
Probably something special with CustomShapes - they create their geometry using 'hidden' SdrObjects and these use groups/3DScenes.
Comment 4 Armin Le Grand (allotropia) 2018-07-13 16:11:02 UTC
Problem identified: In ViewContactOfSdrObjCustomShape::createViewIndependentPrimitive2DSequence the 'hidden/tooling' SdrObject hierarchy for emulating the CustomShape content is traversed using

                SdrObjListIter aIterator(*pSdrObjRepresentation);

what creates a SdrObjListIter in mode DeepNoGroups.
There the behaviour *has* changed:

Old code used

    if ( dynamic_cast<const SdrObjGroup*>(&rObj) !=  nullptr )

to decide if it's a Group, while new code uses

    const SdrObjList* pChildren(rSdrObject.getChildrenOfSdrObject());
    const bool bIsGroup(nullptr != pChildren);

which is more correct due to E3dScene *having* children, too.
Thus for the SDrObjecvt being a 3D scene:

 Old code -> only the E3dScene was added to the SdrObjListIter
 New code -> due to 'DeepNoGroups' the E3dScene gets *not* added, but the ExtrudeObject

Problem is that this is - in principle - more correct. Ergo, the old code only worked due to an error - to handle E3dScene *not* as GroupObject.

Have to think about how to fix that mess...
Comment 5 Armin Le Grand (allotropia) 2018-07-13 16:15:15 UTC
I also understand the 'yellow lines' visualized here - this is the fallback for 3D objects that someone tries to visualize outside of a 3DScene context...
Comment 6 Armin Le Grand (allotropia) 2018-07-17 08:06:58 UTC
Checked if iteration is needed at all, seems not to be the case. That would be a good solution.
Checked with more complex CustomShapes (which are represented with more than one visualization-SdrObject) and compared with libreoffice-6-1, looks the same. Especially the 'smiley' is strange, the eyes are there but pretty much invisible (can be seen when rotating) - same as in libreoffice-6-1. This should be overhauled, it is just a bad visualization, but in a nother task.
Comment 7 Armin Le Grand (allotropia) 2018-07-17 08:18:01 UTC
Have written tdf#118795 for the bad visualization of 3D-CustomShapes

Comment 9 Xisco Faulí 2018-07-27 10:16:20 UTC
@Armin, should it be cherry-picked to 6-1 ?
Comment 10 Armin Le Grand (allotropia) 2018-08-01 18:17:31 UTC
@Xisco: Different mechanism, would need some extra work. Not sure about risk

Actually, the issue is not reproducible in

Sorry for the noise!!
