Unreal has done an important thing in pushing toward direct color, and this gives the artists a lot more freedom," he said in an article written by Geoff Keighley for GameSpot. "I doubt any important game will be designed with 8-bit color in mind from now on.
Even though Unreal was designed to compete with id Software (developer of Doom and Quake), co-founder John Carmack complimented the game for the use of 16-bit color and remarked its implementation of visual effects such as volumetric fog. It also integrated a level editor, UnrealEd, that had support for real-time constructive solid geometry operations as early as 1996, allowing mappers to change the level layout on the fly. Despite requiring a significant personal effort, he said the engine was his favorite project at Epic, adding: "Writing the first Unreal Engine was a 3.5-year, breadth-first tour of hundreds of unique topics in software and was incredibly enlightening." Among its features were collision detection, colored lighting, and a limited form of texture filtering.
Steve Polge, the author of the Reaper Bots plugin for Quake, programmed the artificial intelligence system, based on knowledge he had gained at his previous employer IBM designing router protocols.Īccording to Sweeney, the hardest part of the engine to program was the renderer, as he had to rewrite its core algorithm several times during development, though he found less "glamorous" the infrastructure connecting all the subsystems. With regard to audio, Epic employed the Galaxy Sound System, a software created in assembly language that integrated both EAX and Aureal technologies, and allowed the use of tracker music, which gave level designers flexibility in how a game soundtrack was played at a specific point in maps.
Sweeney particularly criticized the quality of OpenGL drivers for consumer hardware, describing them as "extremely problematic, buggy, and untested", and labeled the code in the implementation as "scary" as opposed to the simpler and cleaner support for Direct3D. While OpenGL and Direct3D were supported, they reported a slower performance compared to Glide due to their deficiency in texture management at the time. However, over time, it was able to take advantage of the capabilities provided by dedicated graphics cards, focusing on the Glide API, specially designed for 3dfx accelerators.
