The Quake 3 code is also incredibly clean. While containing significant amounts of new and overhauled code, the engine is ultimately based upon the version of Blam used in Halo 5: Guardians and still retains remnants of this engine. Keep in mind that the game is over 20 years old, so you may need to dig a little deeper, check the internet archive, get used books of eBay, whatever. The Slipspace Engine is a heavily revamped and modernised game engine developed by 343 Industries, which is derived from Blam. You can see examples of how the same basic engine can still handle some things quite differently in exploring how the old Thief games rendered the world.Īnd of course, if you really want the nitty gritty details of Quake's engine, you can peruse Michael Abrash's extremely in-depth tome on the matter. There are actual, honest-to-god paper books you can buy that explain how to mod Quake 3. GLQuakeWorld: QuakeWorld multiplayer, OpenGL renderer. QuakeWorld: QuakeWorld multiplayer, software renderer. GLQuake: NetQuake multiplayer, OpenGL renderer. But you can already see how calling it a "true-3D-brush-and-BSP-using-scanline-rasterization-engine" starts to get a little cumbersome. Pick and Mix The four original Quake engines cover all the combinations of those variations: Quake: NetQuake multiplayer, software renderer. There are several other ways in which you could classify the engine (such as how it rendered the environment front-to-back but still wrote to a depth buffer for handling the rendering of mobile objects, like characters). It used scanline rasterization, as noted in the comments, to produce the final scene image. Theres no such thing as 'putting Quake into UE5', they use completely different programing languages, internal engine structures, asset formats, map. Then you will have a very authentic quake in UE. Generally I think I agree with the other answers, that Quake 2 had better mechanics while Unreal had. The best plan is to re implement the engine functions used in scripts and integrate the quake c byte code execution engine into your UE code. It is a BSP engine, because after pre-processing the brushes that define a map, a BSP tree is built for dealing with polygon visibility. Unreal Engine 4 and 5 are freely available to publ. It is a brush engine, in that it uses oriented convex 3D geometry to define interior spaces of the game world. It's a true 3D engine, in that it could render actual 3D geometry and not the sort of extruded and offset 2D maps of some of its predecessors. Companies fell into line with their games based on either the Unreal engine or the Quake engine. That said, the Quake rendering engine does has several identifying features: Two competing games: First it was Unreal vs. There isn't a single term for it (other than "Quake-like" or similar), because rendering engines can differ or not in a variety of ways.
