Creating the beautiful, ground-breaking visuals of The Tomorrow Children on PS4

Q-Games details the innovative methods it’s using to help its game stand out

Hi everyone, today I’m going to talk a little about the tech behind The Tomorrow Children. Hopefully you’ve all seen the trailer and are wondering how the glory we managed to get that crazy surreal look we have.

When the project started we had a meeting with Mark Cerny and he said “I want Q-Games to do something that’s a little…outside the box”. So I took that to heart and decided to use the PS4’s awesome compute power to drive three things: Cinematography, Lighting, and Geometry.


So I immediately drove the technology towards “cinematography” which I think is a much more visually stunning style compared to CG that strives to be realistic. Realistic graphics give us directly what we can see, but cinematography also gives us what we imagine we’re seeing. So for example if you are looking at a green field on a cloudy day, the raw photons hitting our eyes are actually a bit of a dull green but the brain’s imagination (and this is different for every person) spruces up the image we are seeing, making it more stimulating and exciting.

Pretty much every movie you have ever seen has gone through this kind of ‘colour grading’ process, the most recent ‘fad’ of which is a process called ‘orange-teal’ which boosts orange in the highlights and blue in the shadows plus a number of other tweaks. Recent TV series such as Breaking Bad, Utopia and True Detective rely on this heavily to set up atmosphere and scene tone.

So I thought to myself, why not do this for games too – but not via a few simple ‘tone mapping’ parameters, let’s go the whole hog and create a professional cinematic colour grading process. And we have two major advantages over cameras and their sensors. The first is that a modern 3D pipeline generates a larger dynamic range of colour which gives us more freedom, and the second is that we have ‘Z’ information for every pixel which lets us introduce Z as a parameter into the colour grading process. This lets us do things such bring up black levels in the distance, or even swizzle colours around a little based on distance from the camera.



Okay, with that cinematic feel to everything, we started investigating how to get a ‘pre-rendered’ look to our 3D in realtime and we decided we were going to have to go all out and do something that no-one is doing. So we researched and invented something called ‘cascaded voxel cone ray tracing’. The concept is a little complex but it involves calculating and storing light and its direction around the player as she moves in ever increasing cascades of data.

Because we have volumetric data (the voxel cone part) it means we can bounce light around fairly cheaply and any one pixel on the screen has up to three bounces of light hitting it, and from all directions too. Now, by the third bounce, the light is quite diminished in power but it makes that subtle difference that tricks the eye into thinking it is looking at something with true presence.

Interestingly most Pixar-style CG movies that you have seen are only using one bounce and although they beat us in detail because they can spend 30 minutes or more rendering one frame, our lighting is a lot more subtle and effective. For example, we can move a big red object around in real time and watch the sunlight reflecting off of it bounce onto the surrounding objects, and then watch that light bounce again onto other nearby objects that wouldn’t normally be lit (indirect lighting).


Finally, we needed some other new tech to build the game around so we started looking into techniques to do deformable landscapes. We wanted something you could dig and mine, or create shapes in but we didn’t want anything too strongly grid based; we wanted it to feel more real. So we went with something called Layered Depth Cubes, which is a way to represent the world without using polygons. Instead, it’s represented as volumes, which are then converted to polygons as needed (for example if the player goes near them and they need to be actually drawn on screen).

The benefit of not using polygons means the data is far easier manipulate and we can do boolean options (addition/subtraction) on the data to cut out holes or to add details and the whole structure remains solid and intact.

The added advantage of course is this all ties in with the lighting above to give it quick, easy-to-access data structures to bounce its light through!


These are just three areas of technology we’ve created for The Tomorrow Children and without the amazing power under the hood in the PS4 none of them would be possible. The future of 3D graphics is here and it is beautiful!

Did you enjoy this?

Release date?


Looks & sounds AMAZING 😛


I’m looking forward to this. Now all that we need is a decent theme park game and I he everything I want in terms of genre on the ps4… Oh and a rogue squadron style game 🙂

Very interesting, visually it’s indeed very impressive, I even thought it was CGI when I watched the reveal trailer.

So you and your team have definitely done a great job and it looks you nailed the style you were going for.

Also, I love the fact that the game’s premise is so out-of-the-box. Very orignal concept, well done.

Looking forward to seeing more gameplay, I liked the snippets I’ve seen here in the videos here so far.

Looks absolutely fantastic. Guess all those people who thought they were being offensive saying the Gamescom trailer was CGI, have all of a sudden shut up and would never say it was CGI now since that is actually a massive compliment and credit to the team 🙂
So great to see yet another truly next gen game in the pipeline on Playstation.


Finally !! Something people aren’t hating on…

I really want to play this. I love the creepy undertone to it.

This is very high on my wishlist

hope i get into the alpha

I THINK IM IN LOVE WITH THIS GAME!!!…. I need some serious help :

yassineya 25 October, 2014 @ 10:04 am   10

I would get a PS4 just for this game!!

THE_FORCE 25 October, 2014 @ 10:23 am   11

Finally….some graphics for the new generation!


Unfortunately it looks much nicer without the vignette, blur and dulled colours.

    Then you need to actually read the post because that is exactly what it ain’t.


Looks amazing and I love the art direction! Hopefully it plays well also 😀


Veeeery nice, can’t wait to see more – ultimately play the game!

Looks amazing, hoping for a great gameplay experience

All I want to know is:

Release date or at least a timeframe better than 2015 – seems games are being revealed earlier and earlier with this drip feed of info and they rarely live up to a full year of hype, see Watch Dogs or Destiny.

Price, unlike the other regions games have increased in price here in Europe by 30% as we are asked to subsidise the US and Japan price freeze from last gen. There are loads of games on the PS4 that were on my “day one” list but I simply cannot justify 55 quid for some retail titles that are the equivalent of 40 quid in the US or digital games that would have been 16 on the PS3 asking for 25 on the PS4 then turning out to be quite poor like Styx.

And lastly, will this have a retail release? Me and my girlfriend are both interested, but as my girlfriend can’t play me PS4 games unless I set my account primary on her PS4 and she signs in as me so I can’t be online while she plays were not buying any digital games that we both want unless they’re on some crazy sale, which don’t happen often here in the EU and when they do its the same four titles every time, AC4 and a couple EA launch titles.

How to play please Answer me Please im want play her
