Setting a 3D environment reference

I'm setting a Frustum camera to create a Virtual Reality environment that looks like a window when you look at the screen. I've checked all the documentation of the SoCamera, SoFrustumCamera, SoPerspectiveCamera and SoOrtographicCamera, but culdn't find a way to set my scene in order to match its borders with the borders of the screen.

I want to do something like this...

The problem on my code is that the whole scene moves, instead of only the "back" of the scene. It looks 3D, but doesn't look as immersive as a real window.

Does anyone have a hint or can help me on that? Im making my code in C++, using OpenInventor. Thanks!!

Solution

  • I think you might need an off-center perspective camera in order to do perspective shifts like in the youtube clip. Take a look at DirectXMath XMMatrixPerspectiveOffCenterLH() function. Maybe that'd help.
