Doom used a technique called **[BSP rendering](bsp.md)** that was able to render [realtime](realtime.md) 3D views of textured environments with distance fog and enemies and items represented by 2D [billboards](billboard.md) ("sprites"). No [GPU](gpu.md) acceleration was used, graphics was rendered purely with [CPU](cpu.md) (so called [software rendering](sw_rendering.md), GPU rendering would come with Doom's successor [Quake](quake.md)). This had its limitations, for example the camera could not tilt up and down and the levels could not have rooms above other rooms. For this reason some call Doom "[pseudo 3D](pseudo3d.md)" or 2.5D rather than "true 3D". Nevertheless, though with limitations, Doom did present 3D views and internally it did work with 3D coordinates (for example the player or projectiles have 2D position plus height coordinate), despite some dumb YouTube videos saying otherwise. For this reason we prefer to call Doom a **primitive 3D** engine, but 3D nonetheless. However Doom was not just a game with good graphics, it had extremely good gameplay, legendary music and art style and introduced the revolutionary [deathmatch](deathmatch.md) multiplayer, as well as a HUGE modding and mapping community.
