@@arzr_er There's a difference between not memorizing every API out there and not knowing how to do things. If you are implementing something that requires vector math, it's ok to look up what function/operator performs cross products in your engine/library of choice. In fact, that's expected. What's not alright is not knowing how to compute a cross product if you are writing code that uses them. Same goes for just about every algorithm, no matter how complex - within realm of game development, at least. You don't have to know all the intricate details involved in optimization - though, a good senior engineer will have a domain where they are an expert in these. But you have to understand how an algorithm works well enough to write a simple implementation. Naturally, I don't actually expect this to be the case for a junior engineer, but that should be the goal. That is something you strive towards throughout your career. That means taking an interest in things you are working with and not treating every API call as a black box. Digging into things, figuring out how they work, trying to write our own implementation, even if you know it won't ever be as good as what's already in the library - that's how we get better as engineers. People who don't do that don't get better. And since nobody gets born a good engineer, I can confidently say they never became a good engineer. There is, of course, a flip side to this. Engineers who re-write absolutely everything, because they never learned to search through documentation, the code base, or open source projects as applicable. In my experience, however, that's easier to fix, so it's not a deal breaker in new hires for junior or mid level, in my opinion.

@@konstantinkh It's in fact okay to look up how to do cross products too. Stop being a gatekeeper. It's much more about how workable the code becomes as it grows, if it scales, if it is readable, if it is modular. You are very right in that doing an implementation is good for learning. But then you misinterpret why. That is because you see how battle tested formulas were written. How they have been perfected on, and the structures that exists in the code, the polished optimization that mathematicians have evolved and then you get to imitate that. It has nothing to do with actually memorizing those implementations. You may look at google for even the simplest of things. It is okay. If you get stuck in the thought loop "Do you know how atan2 works?" "Can you write your own ik solver?" trying to just compare knowledge. Nothing like that is actually useful unless you take away how the structures and flow works. You rarely have to re-write any solved formula or tech. You do however need to study it to learn code structures and flow. You arrive at the conclusion that you need to balance rewriting stuff and not rewriting stuff. But that is actually not that useful, just like @ARZRer mentioned. Every function is already at your fingertips. Being competent is not in knowing the science that went into them. Just how to utilize them. How to structure the code so it builds a good architecture.

Now you have the path a cave takes, and you can remove blocks around this path to remove volume.

Marching cube algorithm is an efficient way to generate meshes from a series of points. I think that if you could isolate every cube vertex that's facing outwards, and feed those vertices into the marching cube algorithm, you'd get something more or less interesting. You'll need to make sure that you treat any detached shapes as their own objects too

@konstantinkh

4 жыл бұрын

Technically, marching cubes work off a function defined over some space that you draw an approximate isobar for. But there are several good ways to convert points into such functions suitable for particular uses. E.g. in 3d reconstruction, point clouds, typically with an approximate normal defined for each point, can be converted into a gradient function using something called Poisson reconstruction. You then draw a surface using marching cubes where that gradient function is approximately zero. The resulting mesh then passes close to the original points and has roughly correct orientation. The reason you don't care about it being exact is usually because points you start from tend to have a lot of error and simply joining them together would result in a very bad mesh.

I mean he has to be on your radar but Sebastian Lague did 2 phenomenal tutorials on this and included his source code. Definitely goes over my head, I’ve been experimenting with marching cubes and procedural terrain generation as well. Best of luck to you, looking forward to seeing more!

you are indeed mistaken. (don't worry, i've been there) they're actually just custom generated worms. (spheres travelling in some randomly changing direction while changing radius) think back to when minecraft was just a small world size. after generating the general terrain, tons of these worms are generated to carve out the terrain. ores/trees are custom generations that populate the world too. in the "infinite" generation model, a single chunk generates all the worms in some radius to carve out that individual chunk. the ores/trees are only generated when adj chunks are present. (so they can generate over the boundaries to make it seamless. otherwise it'd all have to fit inside the chunk generating it. meaning we wouldn't have room for larger oak trees either) along with caves there's also ravines. it's just another type of cave generation. (obviously less common) then there's stuff like villages. they're simply a load of pre-made structures being randomly arranged. obviously they aren't generated chunk by chunk like caves are. (since they're obviously a lot less common too) they just generate out entirely into the world and those chunks are saved. like as if we just used some command to spawn a village that goes out of bounds.

Great review.

Thank you for this and posting the code. Also, for anyone who reads this, the PerlinNoise function creates symmetry about the axes (x,y, and z), fyi. I just add 1, 2, and 3 respectively to x, y, and z inputs to the Perlin3D function to get around this. Makes the map a bit more interested and less redundant. Hope that helps people. Also, about to look into getting libnoise working in C#. I keep seeing people talk about how great those functions are for this type of thing.

I know I'm a little late to the party, but if you haven't looked at marching cubes, you definitely should. It's super simple in concept- just appears way more complicated than it is. It will be your best friend with something like this in terms of a straightforward solution. I was able to learn how it works and whip up a simple implementation in about two hours in Java Processing 3 a while ago- really not too complicated.

Just an fyi: the fastnoise library you mentioned is an *amazing* noise library. I believe the is an unpaid one, and one that makes use of SIMD instructions, which makes it noticeably faster. The paid version is just a port made by the author, as the original is written in C++ (which is available on GitHub by the way). It comes with an unbelievable amount of different noise types with numerous settings, including gradient en perturb variants. It is definitely worth checking out!

All algorithms require understanding of logic rather than just knowing formulas. Keep experimenting and you'll slowly stack up clues that will take you closer to your goal.

Damn, cool video!

Lmao I did this same exact thing, with the same steps you did. I even ran through the same problems! I got stuck and then found this video.

"If I hadn't went down this rabbit hole, then I would have spent these last few days wondering what would've happened if I had." I wish I could have come to this realization sooner, I usually phrase it along the lines of "what's stopping you?" I have a bad habit of NOT writing things down, and future me frequently suffers for it when trying to recollect those ideas.

for people just now watching this there is an excellent tutorial called "How to make 7 days to die in unity" that covers terrain generation like this

A friend of mine made a marching cubes algorithm from scratch. Took him 5 months but it worked

I don't know if you'll see this, but have you considered skipping the voxel step entirely? Sample the noise directly for each point as you have, and build a polyhedron out of those points as vertices depending on if the individual points pass the threshold. If a point passes the threshold, check if it's adjacent to a point which does not. If so, it's on the surface of your solid, so you consider it a vertex. That would limit your shape's polygons to the surface, and no faces will appear inside the shape.

I feel like you could get incredibly far using this technique, smoothing the edges, and blowing the planets scale way up. Imagine super mario galaxy mixed with minecraft mixed with some other games I've not played but would fit into the idea.

Damn that’s so cool,I wish I could do that to
