Draw many of the same object quickly in OpenGL

Question

So I\'m working on a game and I need to draw a lot of the same object. Same shape, same size, same color, just different locations.

Right now my setup is like this.

Answer 1

There's beautiful thing in OpenGL, called Display list. NeHe production has tutorial on them which should provide all necessary info and examples. But basically:

GLuint displayList; // This should be class attribute
displayList = glGenLists(1);    
glNewList(displayList,GL_COMPILE);
Renderer::draw();
glEndList();

And in real draw method just:

glCallList( displayList);

Don't forget to actualize precompiled display list each time you add/remove something.
