Real-Time Non-Euclidean Ray-tracer Demo

[varunprime]

This video gets an influx of views now and then due to YouTube's algorithm. I made this when I was in high school and didn't really know what I was doing. I found that my approach didn't scale to more complex scenes and that it worked inconsistently across graphics cards. I'm not up to date with the current state of GPU programming - I think someone who is could make a much better version. The code and last release are available for download, for anyone who wants to look at and improve on it.

Oh, so now I can finally understand what Lovecraft meant when he described stuff as having non-Euclidean geometry like five hundred times in his short stories.

what would be pretty cool would to be a game about controlling space around you.

Hello from the future where Ray Tracing is popular and even Minecraft has it :-)

Non-Euclidean objects have always caught my interest, I feel like making a project with nothing but stuff that doesn’t and shouldn’t make sense

[ShevkoMore]

Finally, an (probably) actual non-Euclidean space!

>Non-Euclidean
Ok, I will call bugs in my raytracer a 'non-euclidean' stuff now, too.

I'm suprised by the amount of videos there are of this concept. The first time I saw this concept I thought it was really unique but to be honest I've now seen a bunch of videos that implement this in various ways, in different engines. I wonder why I haven't seen many games that use this kind of cool space warping.

Wait this vid uploaded 7 years ago!? This guy saw the future

this will be essential when someone tries to recreate the ancient city of R'yleh in a proper C'thulu game.

Man I love the microphone on this! Never change it!

[varunprime]

This version of the rendering engine only supports aberrations, but I'm rewriting it to make something like hyperbolic or elliptical geometry easier - what's nice is the math doesn't change significantly for either of those.

That's not a portal. It's a wormhole. This could be a powerful way to teach relativity with a game.

Damn. Seven years ago. Why has something like this not shown up in a game yet?

[lobiankk]

Lol, this is a 7 year old video, but i genuinely thought it was made like 2 weeks ago...

[Nae_Ayy]

yo I had headphones in when I clicked this video why must you murder mine ears

[anderson-kjzs]

i love this stuff. i always experience this kind of distortion in my dreams. i finally figured out what to call it!

[patrickromero]

this is awesome! I'm sure there are a lot of people (myself included) who would love to see the source code when it's ready

Slowing down the player and stretching the shadows is a genius and simple, there is a TV show called doctor who where there is a spaceship that looks like a simple 1960's police box(it is in the same size of a British phone booth) but the space ship is actually bigger on the inside, there is a game called gmod that has a mod that puts that ship in the game(when you open the doors you can see it is bigger on the onside), but the way that it is used is just portals(I think), but your solution is is brilliant, making the box actually look like it's bigger on the inside.

these are very nice. the world needs all kinds of games with this manipulated space time as a gimmick. man, so cool
