very important:can i move the camera in opengl?

can i move the camera in opengl ,if yes how can i move it to make navigation in an 3_d tube that have an M like shape ,if not then what is the alternative to make this navigation.
By way that is very important for me so please explain it in detail and if you have any samples or code please send it to me.

there is no physical camera type structure: you just move the “scene” accordingly. Check out other posts or do a search for matrix camera and you should be on your way.
