How the First 3D Games Were Created

The development of the first 3D computer games was definitely among the greatest milestones in the history of the entire genre. Prior to the emergence of fully three-dimensional game environments, many titles were characterized by 2D images, pixelated graphics, and side-view gameplay mechanics. As time went by, however, computer science continued developing rapidly; therefore, new techniques were invented in an attempt to add a third dimension to the gameplay experience.

All modern games featuring an open world and real-life physics can be traced back to the very early stages of the development of the 3D gaming era.

The Introduction of 3D Graphics in Games

Until the introduction of proper 3D graphics, game makers relied on tricks that helped achieve the perception of depth and perspective through scaling sprites and making use of an isometric angle. With the development of technology, however, games began using polygons to create real three-dimensional objects. Such games as Wolfenstein 3D, Doom, and Elite showed gamers how much more realistic games can be compared to their two-dimensional counterparts.

Back then, developing such games proved rather complicated due to a lack of processing power in personal computers and game consoles. Thus, a series of creative techniques for optimization had to be developed.

How Early 3D Games Were Made

Early 3D games made extensive use of mathematics and geometry. Programmers used polygons, mostly triangles, in order to build game characters, environment and other objects within the virtual world.

Due to technological constraints, the amount of polygons within the model was extremely limited. This is why early 3D games featured their characteristic polygonal look featuring basic geometrical shapes.

Significant tools applied during the time include:

• Polygon modeling
• Texture mapping
• Wireframe rendering

These tools helped programmers create realistic-looking games despite the limited processing capacities of the hardware at that time. Of all the tools mentioned above, wireframe rendering proved particularly essential in the very beginnings of gaming.

Instead of displaying full-blown objects, wireframes were used to outline the shape of the objects in question which required considerably fewer resources.

The Function of Game Engines

Game engines became necessary for dealing with the technological aspects of creating 3D games. In fact, early game developers used to create their own engines since there was no commercial software at the time.

One of the most important innovations is owed to id Software, which created the engines for Doom and Quake games capable of real-time rendering and 3D gaming environment.

The engines could do the following tasks:

• Character movements
• Collision detections
• Camera system

And these became the base for future innovations.

Limitations of Hardware Affected Game Development

Designing games using 3D in the 1990s involved proper optimization since consoles and computers had very little memory space and were quite weak with regard to processing power in comparison with current technology.

Game designers had to achieve an optimal blend of visual quality and efficiency when working on a game project. Every single polygon had to be accounted for and textures managed in order for the game to work as intended.

The limitations of the 90s birthed a unique low-poly aesthetic that remains popular today. Whether it’s retro-inspired visuals or ultra-realistic environments, the team at 3D Art studio GAMEPACK specializes in creating assets that balance technical performance with striking visual appeal.
