Coding Adventure: Terraforming

I got a bit tired of my simple heightmap-based planets and decided to experiment with generating them using the Marching Cubes algorithm instead, so that I could add a 'terraforming' ability for shaping the world with caves and tunnels and so on. I hope you enjoy!

I find these endlessly entertaining for some reason, so here are few bonus reasons why rocks float in the air (according to GPT-3, by OpenAI): - In the planet's gravity, rocks are heavier than air. But since there is no gravity in the air ~because it's not a planet~ the rocks float. - Some rocks, such as pumice have an air pocket in the centre. The air pocket creates buoyancy, which makes the rock float. - Rocks float in the air because they are not affected by forces such as gravity, which pull other objects downwards. - The rocks are not floating in the air, they are floating on the ground. - The rocks are caught in the updraught, causing them to float.

Yeah. I'm a good programmer. I know that. I've been programming for years, I understand a great deal of it including the concepts in most of these videos. I make my own games and I have a big project in the works myself. However, this guy's programming abilities always make me feel a bit inadequate. Then again, he's probably not as skilled at other things as I am. Who knows? Maybe I'm better at making a game fun than he is? Regardless, I think it's apples and oranges. His implementation of an idea won't be the same as mine, nor will the experience, but we are both likely to make something good.

As a game designer who wants to know what he's doing in all aspects of designing a game, I really appreciate that you share your code as you go on these adventures! It really helps to be able to "learn with you" and have an idea of what went wrong when you try stuff and how you solve it. The depth really helps, as then I have a bit more of an idea of what could go wrong, and, more importantly, why it is going wrong.

[@nightmareblocks]

10:49 actually really surprised me. I never would have thought that the binary of a float and an int could be so different

[@cerealkeepsyougoingeveryda555]

The floating point format is based on the IEEE 754 standard which is based on standard form. To put it simply: In a 32 bit float the first bit is the sign bit 0 = +, 1 = - The next 8 bits are the exponent where the exponent is offset by a bias of -127 So the exponent can be expressed as 2^(n-127) The last 23 bits are the mantissa which is a number normalised between 1 and 2, since the mantissa must start with a non zero digit and binary only has 1 non zero digit, the one at the start is omitted but assumed to be there giving 23 bits of precision. So a whole float can be expressed as: Sign bit * (mantissa/(2^23)) * 2^(exponent-127) I hope your understanding of floats is better now!

[@thomasrosebrough9062]

@@durnsidh6483 From what I've seen the concept of gerstner waves is super simple and generalized. You basically have a sine wave of points, like in the vid, then make each point into a circle and make your vertex that spins around that circle. The two motions combine to make a wave that comes together and apart very nicely. Thats how it works in 2d, I image you could just make the points into spheres instead, and have the direction of the sine waves be an arc across the planet

[@Meoiswa]

@@thomasrosebrough9062 The problem with Gerstner waves in spheres is you'll always have a point (or more?) on the surface where a standing node resides. This is similar to the Hairy Ball Problem, where there is no way to comb a hairy sphere in a way that no hair overlaps or stands up.

I'm basically speechless. Like, I'm not the only one that can't believe this, right?

[@xyzzy3000]

Technically, this has been done before, but Sebastian is very generous to take time to show us the whole process and explain in such detail. He is humble and honest about bugs, which would often discourage those new to programming, and the script explains everything in an understandable way without dumbing things down. All this and with a very pleasant tone of voice. This channel is a gem. The code samples are the icing on the cake, and are interesting even for people who don't use Unity.

Imagine if Astroneer developers actually created Time Machine to watch this tutorial to develop the game

[@joecolvin4203]

Plot twist: Sabastian created the time machine to send Astroneer into the past, along with these videos.

[@too-many-choices]

Plot Twist: Sebastian is actually the creator of video games, and a time machine

[@tedkrapf1302]

Another great video and project Sebastian! Watching you explore at the end, I could totally see my kids playing this for hours on end. Heck, even I wanted to!. Very cool, keep up the great work and explainer content!

[@stealcase]

Amazing production. Your use of music and flow has become so amazing.

If you want to visualize waves on a sphere I would definitely have a look on “spherical harmonics”. We use it all the time in geodesy to visualize spatial data on our globe :) the mathematics behind all this unfortunately is everything but trivial. It was(is) for me at least 😅 cheers and keep up the great videos! Chris

[@natmath2576]

Furthermore, spherical harmonics are complete and orthonormal, thus any function on a sphere can be evaluated with a sum of them. So it would be possible to do as he is doing with noise and layer multiple of them to get less "ordered" results.

[@fangzhangmnm6049]

I doubt if it is computationally heavy for sphs of higher frequencies.

[@sumsar01]

@@fangzhangmnm6049 It shouldn't require matrix multiplication so I think he is safe. It should not be much harder than evaluating a normal sin function. (I even think that is spherical harmonic to something like first order) Depending on which order he goes to ofc.

[@mmyesrice2522]

every time im stuck on something, i think about the problem in your voice and the solution comes so easily

[@Dragonmastur24]

This is just insane!! I'm in awe of your skills, world-builder!

[@TheForbiddenLOL]

Absolutely incredible, as usual. A challenge for you: when the chunk updates, check if any 'voxel' points aren't supported and make them 'fall' towards the center of gravity, essentially adding Minecraft style sand 'physics'. You might be able to modify this for use on water too, replacing the sphere with voxels. You would of course somehow have to store a material type on each point. Also you should look into 'Sparse quadtrees' and their application with voxels for better performance and chunking. Might allow you to make a much larger planet.

[@evannibbe9375]

That kind of physics would make tunnels impossible.

[@ultimatedude5686]

@@evannibbe9375 That’s like the flood fill algorithm he said would be too slow, but much slower

[@Meoiswa]

There's no deterministic way to know if a mesh is "connected" to the "ground" other than by walking through all the vertices until you either find the "center" to be inside the mesh, or run out of neighboring vertices. In other words this would be incredibly expensive to test every time you morph terrain. Also, having "voxels" fall down wouldn't really look like it is falling down, but rather it "blob-ly melts" downwards, because the vertices from which they are composed are static.

[@hyeve5319]

@@Meoiswa I think you could get pretty good performance for the testing actually, since there's a lot of optimizations you can do. For a start, you'd want to use a pathing algorithm such as A* to walk through the vertices, and you could also discount a lot of vertices based on where you've been so far - you only need to find and then run along the edges of the terrain to determine if it's connected or not.

The only series I have my notifications on for! I really love this series and I hope we get to see more of it! 😁

Content to consider: - Rare minerals / materials to find buried within the planets - Seismic tools to detect where materials might be - The ability to build simple objects / bases - Solar panels to power your buildings, charge batteries for your tool - A Heat system to the planet (the deeper you go, the warmer it gets, the better materials / suits / vehicles you need to go deeper) - The goal could be to find all the materials needed to level up your buildings which can then ultimately create a spaceship which can get you off world to the next world - Each world might be easier or harder to terraform in various ways... maybe some have harder material which makes it more difficult to terraform, more expensive to terraform - Each world can have one or two unique materials which can be used to create newer modules you couldnt make on previous worlds - Each world adds an ability to the Spaceship, making it able to go further or longer, act as its own entire base so you no-longer need to create bases on each planet but can instead focus on upgrading your spaceship with the ultimate goal being to develop the spaceship enough to the point it can travel intergalactically, back to "Earth"... maybe you are lost in an alien galaxy and are trying to return home with nothing but your wits and your basic terraform tool

[@MrTazipam]

Such innovative!

[@danielquedenfeld2052]

This project is especially cool to me since we know that Minecraft started as just a prototype like this. Even if it doesn’t go further in the same way, it’s still so cool to watch

[@gustavowadaslopes2479]

Interesting Future projects: - Biomes - Wind patterns (shown through waves, clouds, grass, trees and gust/gale lines) - Tectonic plates (first on a plane, then on a Sphere)

[@scratchndent2149]

Day 1 of telling Sebastian that he should combine all his projects into a massive open universe simulation for people to buy and play

[@FriedPotatoNugget]

This project - and the way you talk about the coding and building involved - eerily reminds me of the issues and complexities I’ve been dealing with while “programming” my brain in order to make my “self” behave in a predictable way.

[@Drrobverjones]

You're videos are super well crafted. Well done

[@glassbirds4153]

Never this fast as I was in meeting, then I went to toilet just to watch this.

[@joecolvin4203]

Odd, I watched this while in the bathroom as well... I wonder how many others did the same thing.

[@Real_Genji]

@@joecolvin4203 I can't watch this in the bathroom. I have to watch it while eating on my big monitor
