Summary0024590: Crash when processing OpenGl_BndBoxPrs objects
DescriptionIn OpenGL_SceneGeometry.cxx in the method:

Standard_Boolean IsRaytracedElement (const OpenGl_ElementNode* theNode)

on line 714 there is a cast:

OpenGl_PrimitiveArray* anArray = dynamic_cast< OpenGl_PrimitiveArray* > (theNode->elem);

The result is not checked against NULL. Although NULL is possible when theNode->elem is pointer to OpenGl_BndBoxPrs, which is not inherited from OpenGl_PrimitiveArray.


The code below called in

MyAISObject::Compute(const Handle_PrsMgr_PresentationManager3d& aPresentationManager,
                             const Handle_Prs3d_Presentation& aPresentation,
                             const Standard_Integer aMode)

causes crash during an attempt to highlight it.

Handle(Graphic3d_Structure) aStruct = Handle(Graphic3d_Structure)::DownCast(aPresentation);
aStruct->SetHighlightColor(HighlightColor);
aStruct->Highlight(Aspect_TOHM_BOUNDBOX);

Here is the call stack.

TKOpenGl.dll!OpenGl_PrimitiveArray::PArray() Line 48
TKOpenGl.dll!OpenGl_Raytrace::IsRaytracedElement(const OpenGl_ElementNode * theNode) Line 715
TKOpenGl.dll!OpenGl_Group::AddElement(const TelType theType, OpenGl_Element * theElem) Line 176
TKOpenGl.dll!OpenGl_Structure::SetHighlightBox(const Handle_OpenGl_Context & theGlCtx, const CALL_DEF_BOUNDBOX & theBoundBox) Line 286

 TelType is a rudiment of old TKOpenGl implementation which usage has been almost eliminated - TelText is the only one which is processed in special way in OpenGl_Group::Render() since TelMarker/TelMarkerSet no more exist.

So I consider removal of this ambiguous enumeration and field (fix OpenGl_Text if needed, fix raytracing code).

 Dear kgv,

branch CR24590 pushed.

This is not exactly what you meant but it avoids the crash at least.
