In my previous i wrote about the games such as HoverTank3D and Flight Simulation which were the one of the building blocks towards the evolution in the gaming world.
Wolfenstein 3D was released in 1992. It really was a step towards the evolution of the gaming world. It was developed using the concepts of HoverTank3D. This game was inspired by the games of 1980's (Castle Wolfenstein && Beyond Castle Wolfenstein). This game was a big success. It helped in popularizing the genre on the PC and having established the basic run ad gun archetype for many subsequent FPS games.
This is cover of the game:
In the Game, The player assumes the role of a World War II Allied spy William "B.J." Blazkowicz, who is trying to escape from Castle Wolfenstein, a Nazi German prison. After the initial escape episode, Blazkowicz carries out a series of crucial missions against the Nazis.
People found this game very interesting. It had 9 levels and the level of difficulty raised as the player progressed in the game. There were more powerful enemies and bosses in higher levels.
Here are some images from the game play.
Technology:
The game uses ray casting to render the walls in pseudo-3D. This method emits one ray for each column of pixels, checks to see whether it intersects a wall and draws textures on the screen accordingly, creating a one-dimensional depth buffer against which to clip the scaled sprites that represent enemies, power-ups and props.
The Wolfenstein engine lacks many features present in the Underworld engine, it ran well on relatively weak PC hardware. The engine uses a vertical scan line scaling algorithm. It calculates the texture coordinate for the pixel at runtime.
After Wolfenstein3D many games of this concept were developed, one of them is DOOM which became a huge success and is played even today by some of the gamers. I'll be posting about DOOM in the next post. So be ready!!!
