How to work with camera in OpenGL 3x?

Question

C++ / C#

Started learning OpenGL and I don't understand this.. I'm going to make a game with a big world. And I want to move the cube. Only that the cube would be fixed in the center of the window. How to do it? Do I understand correctly that I will have to move the entire scene relative to the cube?

Answer 1

In your vertex shader, the whole scene will be multiplied by the projection matrix anyway, so it won't cost you anything in fact.
