  1. Hello, Roman.
    Please tell me, how you make "black edges" on displayed objects in 3D view?

  2. Hi Denis,

    This is basically a combination of shading and wireframe presentations. In your redefined Compute() method of AIS_InteractiveObject you just need to implement that.

  3. Thanks! At last I have tried to realize it. And it works!
    May be I'm do it wrong, but it works good :)
    I just took all files of "AIS_Shape" class from OCC, has renamed them on "AIS_CoolShape" and has combined display modes (AIS_WireFrame=0, AIS_Shaded=1) in Compute method.
