Presenting My Engine, And My Idea
Hi all !

My name is Nicola, I'm an italian programmer, and a DooM-Quake addicted :) I was convinced by a very gentle and helpful mapper (RickyT23) to introduce here my own engine made from scratch.

It's a deferred renderer engine on which I've been working for almost two years. It is NOT made using some existing code, like the quake engine source code, so it's completely different from all the existing quake-based engines.

In fact, it doesn't read BSP file, but the source MAP files. It has a per-pixel colored lightning, smooth shadows (for now only on spot lights), bloom and SSAO. However, everything is still in process and being improved.
It has also a basic physics system (quake-like), writen by me, of course, but maybe in the future I will switch to some library. And it has a basic AI.
It implements all the basic weapons, like pistols, shotguns, rocket and grenade launcher. However, everything is possible.. for example I'll make the DukeNukem3D weapon that resises the enemies :D

It has to be considered as an "amateur" engine, not a commerciable one. Not for now at least. Plus, I'm working alone... it's hard ;)

In fact, it misses many things: sound system, a menu, a HUD. Moreover, it doesn't have a stable version for now.

It's worth saying also that a friend of mine is helping me on writing the LAN code.

I'm gonna link some screen shots, taken from some maps RickyT23 gave to me.


My idea, or better, my dream-proposal, is to make a survival horror game. I was talking with RickyT23 about some maps set like the horror movie "The Thing", in a scientific base in a some isolated place, like the south-pole, with snows, fog, open spaces, lots of scary enemies and everything that can contribute to having a distressing, stressful and neurotic scenario.

I'm a programmer, not a mapper at all.

Question is: is there someone who could help me in this ?

Ok, I've talked too much, it's enough for now :D!

Thank you for reading !

well, I forgot to say that the engine DOES support normal mapping, parallax mapping, emitting maps. And it prefers hi-res textures :)
Unfortunately the maps used in the shots don't have neither hi-res texture nor normal maps, so some stuff cannot be seen. Only in the first shot normal mapping and emissive lightning is used, since I was using quake-retexturing project textures.

where is the engine?

Since there is not a stable version yet, I'm not letting anyone to download it :) As soon as there will be one, I will notify to all of you.
The fact is that I don't want people to see something that doesn't work well.
So sorry :'( 
Looks Impressive 
It has nice eye-candy that does not seem to stray too far from the standard Quake aesthetics. I'm very interested in seeing more, but I support your decision not to release half-finished work. Keep at it, and if you need playtesters or have questions about Quake in general, let us know. I'm sure there are plenty of people here who would like to help out when it's time.

So you're not using the game logic written in QuakeC (progs.dat)? 
Sounds cool. I'd recommend Kell's texture set based off aliens (I can't remember the name) and maybe the snow tex' from Ogro.

Currently working on something so can't help I'm afraid.

Good luck. 
Thank you for your appreciation :) Actually, the only quake-base engine that supports real time shadows and per-pixel lightning is DarkPlaces as far as I know. Besides, my engine is NOT quake based at all, so except from the assets I'm using, I would say that it's different from quake style. It's a completely different engine.

@onetruepurple: not at all. As I said, each line of the code of my engine was writen by me. I'm not using anything writen by others. The only things I'm using from quake are the assets, NOT the code: so only map and models... that is, the arts. In fact, I'm not an artist/mapper. And even if I would be, I wouldn't have enough time do to everything :D


I wrote here to know what people would think about my humble work, and because I'm testing it with quake stuff.
Plus, I really would like to make some sort of game, I mean, a game with a similar quake gameplay and stuff, but running on a completely different subsystem. Honestly, how much are the chances for me to find some mappers that could make some maps for themselves, and for me ? 
Tell You What 
people have been grumbling here for ages about a modern remake for quake.

From those screenshots, this might be the way to do it. As sleepy said, seems to have additional eye candy BUT without deviating form the look and feel of the quake aesthetic. And the rest of the listed featrues seem desirable too. And I know RemakeQuake is in the works, but its still going to be based off an existing quake platform.

NiG, to be honest, I am not sure you will get much interest until a playable version of the engine is available so that mappers can see it first hand to know what it can and cannot do. Also, I think you need to provide mroe information about what formats of assets the engine can read. 
Very gentle lol.

That is all.

The engine doesn't look too much like ass, which is a rarity. 
How does the engine handle culling and determines visiblity if it doesn't rely on precompiled bsps and vis data? 
Here We Are 
@nitin: maybe the screenshots give the idea the engine doesn't deviate from the look of quake just because the shots are using quake stuff altogether. Above all the textures. Some shots are not using Quake 1 stuff, and I dare you to connect my engine to quake's engines.
Anyway thank you for the appreciation, this makes me happy.

Finally, I gotta repeat it: I'm not working on an engine in order to remake Quake. It's designed in order to make a completely new project.

@negke: actually, it does a precompilation of the map, but for now this is done at the time the map is loaded. The renderer is using an octree to handle triangles faster (but I'm about to add another one to handle the entities of the scene). The physics module is using another octree, but bigger that the renderer's one.
To make both the octrees, on a 60.000 triangles map, kinda 15 seconds are required. In the future, this operation will be done offline and stored in a file which will be loaded in few milliseconds.
Except from this, everything is computed on the fly, in realtime, including the visibility data for objects and lights. I'm using a personal approach of "Hierarchical ZBuffer Visibility" [greene-1993] to cull in a fast way as much objects as possible.


Yes, to really convince people I should let them to toy with the engine. That's impossible for now. Instead, I could upload some videos on youtube. This would be better that just some shots, isn't it ? ;)

not sure if it came across that way, but my comment was meant to be a compliment.

I was simply trying to say that this is one of the few custom engine screenshots I've seen that make me able to say: I would like to see Quake in that engine.

I realise that's not your aim, but those were my first thoughts on seeing the screenshots.

Youtube videos would definitely be interesting. 
ah, ok, that's great !! Thanks :) I'm always hoping that something good will come from this hard project.

Actually, since I'm using only quake assets, it's already possible to "see Quake in this engine". But I need some more time. 
it looks nice so far! Can you share any details of the project you're planning to create with the engine? 
Very interesting. When it's 'stable,' do you plan on releasing the source? 
thank you for the appreciation !
Honestly, I don't have a real project in mind. I can't have one because I don't quite know if my engine is good enough to build something for real people to use and enjoy. However, why not giving a try ?
So I need some artists to make the assets, the maps in particular.
As far as single player is concerned, my idea is an horror FPS; I've already explained the concept in the opening post. I would immagine something like "The Thing" movie: open and desert scenario, a scientific base in the middle (some laboratories, a plant, a warehouse, some big antennas, a turret, a bunker) with dark lights, snow, wind, fog... confusion and anxiety :)

I'm asking for some help from you mappers.
Obviously, the maps will be yours, not mine. So if the project will not never get finished, you can always enjoy the maps with regular quake engines.

well, I don't think so. I believe the source code is something very personal, and very hard to make. Besides, I'm not such a great programmer that others want to read my code, and maybe learn. At least, I don't consider myself to be. So sorry :( Are you a programmer ? 
Those Are 
crappy reasons for not publishing the sources. If other programmers thought like that, there would be no open source. Because it's hard to make? Everything that's in any way worthwhile is hard to make! 
You can agree or not, of course. I don't think this is the best place to start a discussion about open souce philosophy. Obviously my reasons are more complex and deeper. If you'd like, we could open a thread and talk about it ;)

Anyway, I like Carmack's philosophy: he uses to releases the source some years after the release of the product. 
I don't think this is the best place to start a discussion about open souce philosophy

if you look in the archives here, you'll see we discuss it at every opportunity :) 
Open Source 
Baker and Inertia didn't show up yet? No one mentioned Quoth?

Wow. That's lethargic.

The short version is that open source is great. 
Doubting Thomas Redux 
I guess your doing you engine for the thrill. Engine coding is decent technical achievement. Congratulations (Beers) ;>

But believing you can turn it into a worthwhile fullscale Horror FPS is a little naive. Other projects, with a much more solid basis, already exist. The Hunted Chronicles, They Hunger (half-life), Penumbra (commercial, but great and free), and The Dark Conjunction for Q3.

Of course it's possible, but implementing it's missing features for Q1 (and even other similar games) is a more realisable goal. And gaining a strong working community without releasing the code, will be kind-of impossible.

thank you stevenaaus :)

I started doing the engine in order for me to have a reputation and a chance to be hired in some game company. Plus I AM a programmer, and coding 3D engines is perhaps the most exiting and artistic (yet hard) thing.

Recently I've had the idea of exploiting the engine to make a short and enjoyable game. That's also why I'm here.
I don't mean to make a worthwhile world-successful blockbuster game. Just a small episode, because I know I can't ask too much neither to myself nor to other people.
Also I can't guarantee anything, like I've already said.

I saw the other conversions you linked. Except of Penumbra, no one is free. And some of them have an old looking graphics. Why artists should be interested in C++ code ?

Anyway, so far my engine is shit too :)
I was just wondering is someone would like to accept an idea, a PROPOSAL, for his next map. That's all. I'm not asking for new models, new maps, new weapons, and all this stuff for me only. Not at all. I just "threw" an idea ;)

thanks !
I think the biggest gift you could give as an engine programmer would be an extendible framework to allow anyone to make whatever game they liked. You know, like we do with Quake, but without the 14-year old baggage of compatibility holding it back. 
well, that could be possible with a completed engine. As I said, my engine is still "work in progress". It's not a complete game engine, it's more like a "prototype".

Anyway, what kind of features would you like an FPS engine to have ? 
Lua Scripting? 
Though that'd be difficult to get right without a continual mapper testbed.

A better request, one that'd probably help you a lot more, is the ability to grab demos directly from the engine - ready to be uploaded to YouTube.
