Quote:But I have infinite object in my scene,do I need to create infinite amount of vaariable?(which is impossible)I am not sure about opengl...i have never used it. But i am pretty sure that 2d and 3d rendering is not much different when it comes to structure. You can have unlimited 2d objects as well. However you cannot have unlimited number of anything when it comes to computers. You will run out of space at some point.
Have you done 2d simple scrolling backgrounds, tile backgrounds for things like top-down RPG's? It seems like you are jumping the gun if you have not. Much of what i read is you have to fully understand and make simple 2d games before taking on a much larger role of 3d. Which i am assuming you are doing because of having 3-dimensional coordinates. At the same time it appears you are asking a question that is from someone who has yet made 1 game ever.
