Coding Adventure: Atmosphere
ฝัง
- เผยแพร่เมื่อ 28 เม.ย. 2024
- The planets in my solar system project are looking a bit hostile and uninviting, so in this video I'll be attempting to add some cozy atmospheres around them.
Watch the previous solar system video: here: • Coding Adventure: Proc...
Some notes:
• I made a little build where you can play with the atmosphere settings yourself, which you can find over here if you're interested: sebastian.itch.io/atmosphere-...
• A number of knowledgeable people have pointed out in the comments that reality is not nearly as simple as my little diagram around the 4 and a half minute mark, and that light does not literally wiggle up and down like a wave, so please note that the diagram is incorrect!
• This project was inspired by the game Outer Wilds, which I highly recommend playing!

When he accidentally makes the best lesson on why the sky is blue.
yeah, and I'd never have thought about why the sky turns red when the sun is low
Ha - was thinking the same thing.
iirc there is a part about how oxygen actually "looks more blue than violet" too, but I think he summarized things in a quick and good way that clearly passed the message that "there are several reasons that contribute to the same effect" (not to mention that iirc it was also debated whether what I mentioned was to such a small extent it could be considered *entirely negligible* in terms of the sky's color)
Sebastian’s videos are more tutorialish than one with “tutorial” term in titles!
I think I will show this to my scienze teacher 😂
"my favorite programming trick: calling a function that doesn't exist and worrying about it later"
You're my hero dude lmfao
I was gonna say, that's actually a pretty useful way to make sure your functions are all nicely decomposed rather than trying to cram everything in, train-of-thought style.
SS2Dante oh for sure, I do the same thing
I tend to do the opposite. Write a function, forget to call it and wonder why it's not working.

He already destroyed Spore's planet generation in the previous episode, so No Man's Sky is for sure next on the list.
More like Outer Wilds 2
No this is way more like outer wilds than NMS.
@@_Killkor Ha. No one is going to touch NMS planet generation for a long time. Everyone's height map performance barely runs better than NMS having not only more points of data in the same FOV. But also voxelates the entire surface. All while running almost as well as even the best competitors. That is seriously impressive optimization. NMS is easily the best optimized game of this decade. It should not run anywhere near as well as it does with that kind of real time terrain generation. All while having graphical affects on par with anything else out that isn't ray traced. And it runs on consoles AND VR quite flawlessly? My very modest 1060 keeps it solidly within max reprojection fps better than any other game I can't run at the full 80 on my rift. Hahaha, no ones going to get close for a long while.

"that sped things up immensely, with the minor trade-off of completely ruining everything"
The story of my programming career right there.
I lost it at that line.
I can absolutely relate to this line's accuracy as a college Robotics major and hobbyist game developer. Nothing, not even a seemingly basic optimization, ever works exactly right the first time. In my experience, only one third of programming is actually devising the logic and writing the program. The remaining two thirds are roughly equally split between debugging and tweaking the numbers.
I've had this concept apply to every single project I've worked on from basic Pong clones to turn-based RPG's to autonomous navigation.

The most mind-blowing part about these shaders is that they look good both above- and below their "surface". This one looks great from space and from the planet surface, and the water one looks great both inside- and outside the water. Absolutely boggles my mind.
That's because Sebastian bases his solutions on actual physics instead of going for easy surface level solutions. The man deserves all the credit he gets and then some!
@@masamainio4052 Looks great, but is not based entirely on real physics. He did use some tricks to make it easier. The red colors should not appear when looking from outside the planet.

When you program good, code will work even in situations you didn't plan.
@@AkiRa22084 i do not think that is how it works, filthy weeb
Bruh So what you're saying is that you don't program good.
Your ability to visualize and present concepts of all kinds is actually one of your strongest points. The editing and visual elements combined with music infused with your personal touch (hand drawing explanations) is a real highlight to everything. Regardless of topic, I'm sure you could make it interesting. I just happen to love your coding adventures.

Nah mate we already have spore for that...
Moral of the story: If you can't model great and beautiful stuff, just procedurally generate them.
As easy, as that...
This makes me feel like I'll never be an even decent hobby programmer.
The best I can do is make a barely functional pointless Python program every few years
Just start with a simple map, something achievable with your skills. You can start with the course "procedural map generation" with Brackeys. Then increment your project, still with something doable, etc. Each time you'll add something, you'll get better, and so will be your project. And one day... your virtual world may become something wonderful :)

This stuff just makes me realize how crazy complicated real life is
Every other person you see is as real and complicated as you. Sometimes i refuse to believe this because of how insane it is
well we are a bunch of atoms that are attracted to each other and not a single object , that's what messes with my brain XDDD
And in theory if you could know enough about everything, break it all down mathematically, and calculate it all from the big bang, you'd be able to know the future through every cause and effect chain
@@EKIANandWolvesGaming nah I get why that seems to make sense but there are truly random events happening all the time. The spin of a quark for example, when it is formed
@@EKIANandWolvesGaming I think one of the main problems with that theory is that you cannot know / have complete precision of natural values (acceleration, etc.), and those precision errors will cause prediction errors over long periods of time due to the butterfly effect. Though perhaps it could be precise enough to at least be accurate for a few billion years...though of course it would still require an impossibly large amount of processing power.

Whenever someone makes some asinine comment like "you don't need math to be a successful programmer". I just refer them to your videos.
The more I watch your series on making this solar system, the more I appreciate what Maxxis went through creating SPORE. That might be mostly because Spore doesn't look too far off from what you've made thus far, though with today's tech and such you'd likely be able to make something that looks a bit better.
In any case, loved the video.
This was so interesting, and the result is absolutely stunning! Looking forward to the next one man.

so thats quantum mechanics.
IMO they can but you just need to take so much time explaining it gradually that they already are a year older or something. Like how you dont learn everything in school in 1 year but 12
At this point it's fair to say these are devlogs, not Coding Adventures.
A bit of both, I'd say. Definitely far more experimental than most devlogs.
Yea. Kind of. Feels like an adventure to watch. But oh man the depth he goes to
Both
After spending 4 years to get my astronomy degree, I feel vindicated to hear optical depth used properly for cool reasons, and when you decided to normalize your unit system to 1 for simplicity I nearly cried
same! god I wish I normalized my simulation of the surface of the star, I spent too much time checking the numbers with a calculator.
I reaaaally like the transition from the black space sky to the atmosphere. So natural.
7:41 Reminds me of my favorite programming trick, which is writing a function and forgetting to call it later
Mine is creating a function, changing the name, then forgetting I changed the name and wasting 3 hours.
I declare a function, make the function and then the program decides to not let me call the function
Like 2/3 functions can't be called because the program doesn't like them, while the others have no problems
And then re-writing it only to end up with a worse function
I call it before actually creating it or when it‘s just a construct which returns nothing.

I absolutely love the way you have done this series, not only is it fascinating to watch and see what you managed to achieve, but as a coder also interested in these topics, it is very valuable at pointing out various techniques used, and even explaining and visualizing them to a degree to make delving into the topics easier(plus I know what to look up in order to get full details on a topic).

My man is literally making Outer Wilds as a solo dev
Ikr after watching the video I want to play Outer Wilds again
While also making a video series on it, and making it flawless while at it, because the rest wasn't enough.
procedural planets wouldn't work for Outer Wilds. this is like No Man's Wilds
@@SoulSukkur I would guess that the Outer wilds planets are at least partially procedurally generated at some point and then they went in and modified them.
@@perfredelius8060 I watched the making of documentary from noclip and they didn't suggest anything like that. they discussed how they had to design Timber Hearth as layers of spheres, and then they had to overhaul that for the Ember Twin, which has more complex geometry. everything in that game was made deliberate. they talked about how annoying it was to make brittle hollow, which has the highest level of surface detail. they had to model each of the flat bits individually.
Honestly, i don't see how there would be any design benefit to procedural generation. if you want to have a way to generate as many unique-but-similar moons as you want, then go ahead and make a random crater generator. but Outer Wilds only has 3 moons, and only one of those has craters. designing systems to procedurally generate things you'll only need once is so inefficient. just make a sphere and sculpt some dents into it. no math, no parameters, full artistic control.

episode 100, how to code self avare life forms
This actually isn't completely unattainable. For a game, you wouldn't actually need to simulate the entire universe at the same time, just the region close enough that the player that they can meaningfully observe it. The rest can just be loaded/generated "on the fly" as needed, or unloaded to save space (pun intentional) if it is no longer inside this region. Methods like this are often used to enable games to have extremely large, and sometimes practically infinite, worlds (or universes in this case) that couldn't possibly fit in memory in their full forms; Minecraft is probably the most famous example. I've even seen Sebastian implement systems like this on other projects, so he could easily simulate an entire fictional universe.

This might be the greatest coding video I’ve ever watched. Wow. Just... wow...
You’re a baby god, learning how to make a universe.
Bugs that i've found so far(in the demo):
1. Stars are visible through the ocean
2. Scattering doesn't apply on the ocean reflections/glares
3. The ocean reflections/glares are visible even when the sun is under the horizon
Put this in the itch page.
The oceans are almost definitely temporary.
Oceans aren't really there. It's all just a shader based on planet's centre position. Sebastian would need to make them more of a "physical" in-game object over just a screen space shader
Electromagnetic waves don't "undulate" through space like that. We say they're transverse waves because they are formed by electric and magnetic fields that point perpendicular to the direction of travel. The wave itself may have a volume, or it may be very narrow, depending on the light source, dispersion, that sort of thing.
What's actually happening is that the air molecules are being polarized by the oscillating electric field of the light traveling through it, which makes them behave like tiny little antennae and reradiate. These molecules are like mass-spring systems; they have a natural frequency they "like" to oscillate at. This resonance frequency would be the frequency that would result in the most efficient scattering. Well, it turns out that for air this frequency is actually in the ultraviolet, which means the "higher frequency = more scattering" rule works, but only for visible light. If the sun output more energy in higher wavelengths, and your eyes were sensitive to those wavelengths, you might expect the sky would be purple.
Well said. You can actually see that uv light is scattered more in practice if you use a uv camera. If you were able to see uv light, the world would be extremely misty and thick as the atmosphere is scattering the light a ton.
earth is flat
its hard to tell if @Sr-71 Blackbird is a troll. I hope so
also, great explanation! Thank you!
@@syfou725 dont worry i am a troll
Wow the way you explained the colours of the atmospheres was amazing. If I was taught that in school I probably wouldn't have got it at all.
I love this. You have such a calm and relaxing voice. You're talking about such interesting things and it's for coding. Literally nothing I dislike about anything here
Your videos always amaze me! I love that you take a very physics based approach to most of these coding adventures, and the end result is beautiful!
Happy you liked it, thanks!
@@SebastianLague Please keep up the quality, man. I'd ask for that request, and also thanking you for your efforts.
*Note:* I'd like to resend similar messages again in the future videos.
"I've long since lost any faith in the code I write" same, man. same.
These coding adventures are just stunning. Absolutely great work.
A very original and well-made physics/coding video. Very refreshing, thank you.
The way he acts like he's just a normal programmer makes me regret my pay cheques...
People have already done these things.. he learns from those people..
Pretty sure programmers do very complicated things like this.
I am not saying it isn't amazing but he isn't the one to come up with everything, he learns it from other sources too.
@@elythas128 I am a professional developer. Very few devs have the ability to not only abstract the maths problems this well, but to also explain it so concisely... And I work with an ex-maths teacher now programmer...
@@elythas128 That has nothing to do with my comment though?
@@elythas128 See you've already demonstrated my point... You couldn't even decipher a 15 word TH-cam comment, let alone a university paper
@@YouReyKarr Yeah sorry I responded to the wrong comment, well no, it was more confusing, I responded twice, you responded to my response, but I thought the original comment was another one, sorry for the misunderstanding. Also I am not sure why would you degrade me when I did not attack you in any way, sorry if it seemed so. (And no, I don't think I could decipher a university paper, not without prior knowledge.
When the sun started to go away and we saw the stars, it made me say "WOOOW" really really! Congrats!!!
I don't think I currently know any other channel that shows principles and coding areas that visually pleasing and well written.
I have been waiting for the new upload like its the day before Christmas, this video blew my mind.
In five years he's gonna make a video like "I was messing around with variables to make self-aware AI creatures."
I love that you include the parts where you mess up. The mistakes are often my favorite part
These video's are about what he want's to explore, things he wants to try. I have tried doing similar things on a smaller scale and honestly the biggest joy in some ways is when it doesn't go right.
It's easy for someone with more experience to produce a "perfect" video that doesn't show the mistakes or his frustration. By showing you all that he is first saying that you probably will never write perfect code first time, but, also that mistakes happen even when you have more experience
I love watching these videos, despite the fact that I have absolutely no idea what he's talking about.
I've watched this series 2 times its so interesting, i recently started coding and I wish i will get as good as you, keep on making great videos
that feel when you accidentally discover God's secret TH-cam channel detailing how he made everything
Fun fact: those planets were once a untextured coloured sphere.
before that they were cubes!
Alex A wait seriously??! No way!
So much Potential in the Blender default cube
for some reason I can't stop watching your videos... it really puts into perspect how much I have to learn as a new game developer with only a couple tutorials under my belt. can't wait for the next video. :)
It really gives you a good visual of a still frame of the transition from blue sky to sunset/sunrise and night
