Advanced Open Source Engine Based On Quake 3 137

An anonymous reader writes "Phoronix is running a news story about the XreaL project, which its lead developer claims is the most advanced open-source game engine. XreaL is based upon the vintage Quake 3 engine, but it has been rewritten over the course of many months such that it no longer resembles the original id Software engine. The XreaL engine has its renderer written entirely in GLSL with compliance toward the OpenGL ES 2.0 specification in mind, but it supports the new OpenGL 3.0/3.1 specification and is able to take advantage of its new features. XreaL has also added an HDR pipeline to its engine and on modern hardware is actually GPU — not CPU — bottlenecked. XreaL can also load game content from Unreal Tournament 3. This engine, which is described to be as powerful as what can be found in Doom 3 or Call of Duty 4, is written entirely with free software. The XreaL project has created plug-ins for Maya to broaden their game development capabilities."

      YAFPS

      Not only YAFPS, but also the screenshots are poorer than other FOSS FPSes. For example, they lack basics such as dynamic shadows.

      It seems the article authors got excited from the claim that the engine is written in GLSL and is OpenGL 3.0-focused. That, and the engine developer is not exactly humble, with claims like "definitely the most advanced open-source game engine".

      Instead of dissing other engines - which offer greatly superior visuals, to boot, just look at screenshots - he should let his achievements speak for themselves. They don't, thus far.

        I have seen impressive screenshots of the XreaL shadow-mapping capabilities. However, other engine projects seem to have more/better artists. It is not easy to show off all the latest tech using modified Q3A maps.

        In fact, I am uncertain if using the Q3A code as a base for something like XreaL is wise. It might be better to start the graphics part from scratch, since the Q3A graphics stuff is from another era.

        "basics such as dynamic shadows"

        That's basics? Wow, times change fast these days, even I can remember the time when "dynamic shadows" weren't basics but rather bleeding edge, something you'd need a killer machine for to pull off at all. Maybe 'cause it ain't been a year ago or so.

        You know what "basics" too many games lack these days? An interesting concept, some originality, replay value and generally something that makes me want to play them. If you can put that in a game, you can keep your eye candy. Eye candy is like new car smell. Yeah, it's nice, but it wears off too quickly and after it's gone, you only get to see that you have, essentially, the same crappy game that you didn't want to play a year earlier already.

        If this means we have now a good FOSS engine at our hands that allows the development of games without first forking over six digit sums and thus being pressured to deliver something "mainstream digestable" (read: uninspired copy of something that sold well), we might get to see a few daring new ideas.

        • I agree 100% with what you say in this comment - you're exactly right. In fact, you are so right that I've been working on a FOSS project with exactly this motivation in mind: Ease of development over eye candy, while still maintaining decent 3D visuals.

            This will probably be modded down, but it's worth highlighting. Diablo II looked great for its era, and was basically a 2D engine. Duke Nukem 3D was really 2.5D, but unless the monsters got really close it often looked much better than Quake (for one thing, duke3D could happily run at 800x600 on machines that struggled to do more than 400x300 with Quake).

None of those things are object code linked to the engine. They're all just data as far as the engine is concerned.

We tend to see our art as this super-precious excretion of our SOUL and there is no WAY we'd let just ANYONE play with THAT. And again - this is the culture surrounding the core skills.

      • A few reasons why you tend to see that:

        1) Commercial games have better tools. Many OSS engines seem to have NO tools for people who develop anything but the code. Often commercial games have some really solid ones. Unreal Tournament 3 would be an excellent example. Its tools are top notch. This is of interest to people who are making mods. If you want to do level design, you'd much rather do it with an excellent level editor than in a text file with only some vague descriptions of what does what.

      It's not just how open source games look. It's their whole production value, the impression that every part of the game is designed to fit some kind of vision.
      Most open source games feel like they're build around some code that was produced without any kind of vision, with someone else entirely picking it up and extending it.

        That's what I was thinking. Why not sell your game on disc and include the source on the disk. Maybe even throw in an open source compiler specific to the target platform, with adequate "tech support does not support compiling issues" warnings of course.

        You're not selling the engine, you're selling the game data, and giving the engine away, like you should be. Putting the source on the disk itself (as opposed to the required link to source) might even serve to bring a few smart gamers into the programmin

        • I think the link to source makes sense too. Link on the web site, that is. If you make any modifications at all to the source code of the engine - even if it's not related to the functionality of the engine itself (fixing error message typos and so on), you'd be charging for the source code if you required the purchase of a CD to get at it.

        That depends on how many game rules are part of the game engine and how many are in interpreted scripts.

      If you look at the FAQ, you will find that they use the GPL. Not the LGPL. Which means the commercial game companies would have to hand out the source code for the entire game. Not gonna happen.

      • Has this issue been taken to court yet? I think it's a real stretch. Including different game data doesn't count as "dynamic linking." That's like including a JPEG file on a disc with Gimp.

        If the engine is written so that this is required, then make the necessary changes to the game engine and release those changes for free.
      • If you tied, say, the Lua engine into XreaL, and wrote all your game logic in Lua, then you'd be fine keeping that source closed. The artwork would be similarly protected.

  • I am looking forward to Intel's ray-tracing solution, that will make creating of any game *much* easier. Just place your objects to scene and there you go, no need for object simplifying algorithms and computing of all sorts of stuff related to lighting. If they bind it to Java in some smart and powerful way, everybody and my cat will be able to create great-looking games. Finally, playability part will become major factor instead of stupid shadows and FPS.

        It shouldn't. The ray tracing will be handled by the hardware/library. And Java's JIT compiler is getting pretty dang good.
        Try Eclipse.org sometime. While not a game it will show you just how good a java application can be.

        • I have actually tried eclipse and I found that because my hardware is somewhat old (7 years) it runs too sluggishly to be nice to use. Apart from games there is not much other software which I have come across which I have had any problems with. Thus I would be forced to conclude that the Java performance is not actually good enough for my needs with this.

            Do not get the version with all the plug ins. Some of those are real pigs.

    • If they do raytracing in Java, FPS will become the *only* major factor people worry about.

      There are already numerous easy-to-use game development environments (such as DarkBASIC), but have these resulted in any games that are great-looking or innovative? Generally, lowering the entry requirements for making games just results in people who lack the required skills, knowledge and experience trying to make games - the results are not usually anything to write home about.

      Raytracing isn't a solution, its just another way to tackle the problem. You still have to fix all the same visual inaccuracies that you get in normal rasterization. Raytracing doesn't give you soft shadows, it doesn't give you dynamic scenes, it doesn't give you ambient occlusion, it doesn't give you global illumination and many many more things. You can write a raytracing in a few dozens lines of code, but that will be one that renders shiny spheres, not something that can keep up with a commercial game e

    The biggest problem in the OSS gaming world is content, that is, graphics and sound; for every programmer we need 5 artists at least.
    Game companies usually employ a lot of skilled artists, but their content is closed as hell and is soon forgotten once the game becomes obsolete.
    What if we could allow those companies to use this engine without publishing the source and modifications, which normally would be a violation of the GPL license, but arranged in a way they give in return the use of their art only in

    One of the things these people have to do is take a page from Valve and Epic and look closely how the two created modding tools for their engine.

    Well, Unreal Editor doesn't really allow you to make an entirely new game out of the Unreal engine, but it's an incredible mapping tool, much better than Hammer for the Source Engine.

    But, Valve has other tools as well, such as Faceposer to help in lip syncing your models. As well, the event based choreography of NPCs and physics seems to me to be unparalleled. NPC see's enemy, fire an event, which triggers the NPC to freeze, since the enemy was MEDUSA ALL ALONG! It's very intuitive programming.

    So this engine needs to have an infrastructure in place to make modding as intuitive, as well as tools that make use of that infrastructure.
