Early 1990s Computer Limitations

In the early 1990s, personal computers were fundamentally incapable of rendering complex 3D environments. The processors were simply too weak to calculate which walls were in front of other walls in real-time.

The Development of DOOM

To build the legendary game DOOM, developers had to cheat mathematics. The solution was Binary Space Partitioning (BSP). Instead of forcing the computer to calculate depth on the fly, developers pre-calculated the entire map, mathematically slicing the level into a massive, invisible flowchart of rooms.

Advantages of BSP

This allowed the game engine to instantly know exactly which polygons were visible from any given coordinate, rendering the world flawlessly without melting the processor.
