L.O.D (level of detail)

In this screen shot you can see the players perspective of the game and what he sees on screen the buildings in the background are far away from of the player barly withing the games draw distance so the are very low L.O.D models (level of detail) from far away they look well textured as the human eye cant see lots of detail on far away objects so the textures will be far less detailed as they don’t need to be detailed and this also makes the rendering fast and more stable
In this screen the player can see 2 of the same model at one time one close up and one further away, the close up model has higher detail because the camera is closer to it, the one further away has no need for higher detail so it is rendered in a lot less detail
