Inside a cube.

Hi!

I need to make a program, where character is inside a cubical room. Tried to use Cube for this, but found, that there is backface culling, and I just “see through room”.

Can I make something with Cube two make a room, or just take 6 planes?

P. S. I don’t know how to use Blender…

P. S.2 Will the way in the comments work, if I resize the Cube in runtime?

And I need very much to watch inside the cube, not out the room.
I need something like “Inverted” cube.

Yes, you could just use 6 planes, but their vertices wont be connect, and that might cause problems with shadows and lighting. I’d suggest creating custom mesh (model) in 3d modelling software, like blender, 3d max or maya.
