Why redraw every frame when you only need to redraw if a cube is removed or placed? Doesn't make sense.
It says there's a camera. Can the player move the camera around?
it doesnt matter.. even with a fixed camera.. if you don't _DRAW_ stuff EVERY FRAME, it's NOT THERE.
xD 100% correct
The XNA Draw Procedure
1/ CLEAR THE GRAPHICS DEVICE (To a nice colour) 2/ Proceed to draw the programmers stuff. 3/ End Draw Call
