I 'am a new opencascade user.
I would like to draw 3d items over the opencascade rendering like a NavCube.
I do the rendering like opencascade examples (with AIS) in a QOpenGLWidget.
I try something like this:
draw();// call Handle_V3d_View::Redraw
if(m_pNavCube)// draw the NavCube
But my nav cube is not drawn. If I comment the first line, the opencascade scene
is always displayed, I have no control on rendering.
So I' am on the wrong way.
My truly questions are:
* How drawing 3d objects over the scene (= without Z order)?
* How drawing 3d objects like an HUD ?
Sorry for my english.
