Summary0030516: Visualization - Pointer to an OpenGl_Structure is deleted and accessed later after PrsMgr_Presentation::Highlight()
DescriptionWhen creating a 3d shape(g.e. box) and then displaying it and then shading and then hilighting it and last trying to remove it from every viewer a deleted OpenGl_Structure pointer fails to be removed from OpenGl_BVHClipPrimitiveSet::myStructs

QUICK AND DIRTY SOLUTION FOR MY CASE JUST BEFORE CALLING REMOVE FUNCTION:


    PrsMgr_Presentations &shapePresentations = myAIS->Presentations();
    for( int i = 0; i < shapePresentations.Length(); ++i )
        shapePresentations.Value( i + 1 ).Presentation()->Presentation()->SetIsForHighlight( false );


myContext->Remove( myAIS, Standard_True );

    0030516: Pointer to an OpenGl_Structure is deleted and accessed later
    
    The flag OpenGl_Structure::IsForHighlight is set to false before erasing of an OpenGl_Structure entity to prevent occurence of dead pointers to it in OpenGl_Layer::myBVHPrimitives.

    0030516: Visualization - Pointer to an OpenGl_Structure is deleted and accessed later after PrsMgr_Presentation::Highlight()
    
    Do not set IsForHighlight flag for already displayed presentation.

The problem cause is PrsMgr_Presentation::Highlight() -> PrsMgr_Presentation::display(true) setting IsForHighlight flag for already displayed (but hidden) Structure, which makes no sense. In the following script Wireframe presentation is hidden (but already in BVH tree for frustum culling, hence no use to remove it from there) and revealed by selection:
pload MODELING VISUALIZATION
box b 1 2 3
vclear
vinit View1
vdisplay b
vfit
vsetdispmode b 1
vmoveto 250 250
vselect 250 250


There is a general issue though - when highlighted structure was not displayed, IsForHighlight flag results in no frustum culling for it. Consider selection of entire scene with local selection turned ON (which is unfortunate scenario anyway), it will lead to a lot of structures being not frustum culled. This is a subject for another issue though:
pload MODELING VISUALIZATION
box b 1 2 3
vclear
vinit View1
vdisplay b
vfit
vsetdispmode b 1
vselmode b FACE 1
vmoveto 250 250
vselect 250 250
