You must have some of this already to move the player around. You create some internal data structures that keep track of where your tiles are and where your player is. However, it still does have all your objects in memory in world space. It just has the final Rectangle of pixels. This final screen space is whats drawn onto your screen.Īt that point unity doesn't really know that the reason tile 27 isn't drawn is because Player Sprite is in front of it.

Various algorithms determines which pixels on a 3d object will be drawn onto the screen (if an object is behind another object, how to project the 3d object onto flat surface given perpective, etc).

We then take this Camera space and squish all the objects into a 2D rectangle called Screen Space.

You can think of this as spinning the world around and moving it so it lines up with the camera.

We convert them to a camera space based on where the camera is positioned in the world and what its looking at (its angle).

all the objects are converted to this world space so they have relative position. or a light might be at 0,10,0 10 feet above us). (its at 0,0,-60 for example 60 feet away from us on the floor.

We use matrices to take every object and place it in a world based on positions we assign the object.

They have no knowledge or any interactions with any other object. Usually the object is located at 0,0,0 in its own local space. Unfortunately it can't The standard flow for graphics engine is this: Each object has its own local space (x,y,z axis).
