Is it safe to update the scene graph in the viewer camera's
PostDrawCallback?
Background:
I'm using Dear ImGui with OSG. ImGui is 'called' inside the camera's
PostDrawCallback. And I want to use code constructs similar to this:
if (ImGui::Button("Delete Node"))
{
//remove a scene graph node here
}
I suppose since the PostDrawCallback is executed in the rendering
traversal, updating the scene graph here is unsafe? Am I right?
Does using FinalDrawCallback would make a difference?
Kind regards,
Andi
