Hello.
I've wrtten some questions here so far and got good hints, thank you.

Now, I use HMD, and Polhemus MoCap system. Polhemus transmiter is a cube, so I made a same scaled cube in the 3D world and it is placed at (0,0,0) in world coordinate system (because the real one is at (0,0,0)) .

The HMD is "see-through". So when I use the HMD, I think I can see both the real transmitter and 3D cube. I want to see them like they are piled up through the HMD even if I move or rotate my head (they should be seen like they are at the same position and same size).

I thnik I should control camera, window, or view point or something to do that, so I've created and tried some methods for that. But I'm still confused.

I believe there're good methods for that.
Please give me some advices.

Thank you for reading.
