Coin3d --> Object turning black while moving camera

[apeltauer]

hi all,

has anyone seen this behaviour when creating a coin3d object (here a line and a cone) and showing it in the scene grapgh, that the object is turning black when moving the camera?

It seems that it may has something to do that the object is somehow behind the cube?!

my sample code:

Code: Select all

  PartGui::ViewProviderPartExt* vp = dynamic_cast<PartGui::ViewProviderPartExt*>(Gui::Application::Instance->getViewProvider(object));
  if (!vp) return;
  auto currentRoot = vp->getRoot();
  auto pRoot = new SoSeparator();
  .....
   pRoot->addChild(static_cast<SoCone*>(aDir));
  currentRoot->addChild(pRoot);

Or it's a driver bug.

In some other scenario I also have the issue that the content turns black. For me this is the case when editing a sketch and with the rubber band selection of the Edit menu (not that of the sketcher) the whole content becomes black.

hmmm... this could be true
