Making my Voxel Engine faster

Рет қаралды 45,669

Күн бұрын

I'm making a voxel engine with RUST! (the programming language...)
I originally was making my voxel game with Unity, but my love for the Rust programming language caused me to see if it's viable to swap over to that.
This episode is all about optimizing the code for the world generation.
Multithreading, benchmarking, profiling and data compression, are all things I've tackled with lately.

Practical optimization is two parts memory allocation strategy, one part algorithmic complexity with maybe a little knowledge of CPU caching thrown in. Ideally you minimize the number of memory allocations and adopt algorithmic approaches that bring you as close as possible to O(1). Got a loop that does 1 million allocations, first start by doing one allocation of a million instances and your program will gain performance increase in orders of magnitude. On the low end once you've addressed allocation strategy and algorithmic complexity you can eek a little bit out by removing or simplifying calculations, or finding opportunities to precalculate, etc. Throwing more threads at your code is not optimization. Keep in mind that a modern CPU-core executes billions of instructions per second, and the reason your code runs so slowly is because the CPU is effectively idle waiting for other tasks. Throw more threads at the problem without fixing the underlying cause is not optimization and will only compound the problem. Fix the underlying problem first, then once you have a sleek fast implementation, make it parallel and you'll unlock the true potential of the hardware.

Great work! Really sells the difference between the two engine approaches. One pain point is that Perlin is a very visibly square-biased function for noise. There's a sort of vicious cycle in the PCG community where it's taught far more often than the alternatives which address its issues, and far too often not in the context of techniques which mitigate its issues. As resource creators we should strive to teach the best possible information, and this is an area that really needs it. Best of luck with your channel!

I wrote something similar in Java and later C++ years ago, but went farther, with ambient occlusion, textures, some variability on lighting, proper shadows. I then started to convert it to Vulkan and lost progress as life got in the way. Compression of those vertices is critical, but I recommend you skip the unnecessary bit fiddling and just use bytes for relative x,y,z, and another byte for your "face" (normal). Another key is to reduce geometry by making things like texture and brightness (from MC-style falling light, or ambient occlusion) dynamic so that you can ALWAYS mesh large flat areas into simpler shapes (with simpler geometry than it would be if you used one square per cube). I found moving brightness to textures and using a binning system was optimal. Good luck! I had a TON of fun working on my system! Oh, and be sure to use ambient occlusion, render front-to-back, and if you can, render down the primary, secondary and finally terteriary axis. That was my last improvement, and it made a huge difference in eliminating invisible geometry.

You should run the multithreaded stuff as tasks so they can run across frames rather than running them in parallel in-place like that. Then your per-frame cost is just the cost of kicking off the tasks and just check for task completion to finish things up. A parallel-for for stuff like chunk loading or mesh creation isn't ideal. Maybe even have task dependencies for tasks so you could kick off a chunk load task and then a mesh creation task with a dependency on the chunk load task.

@Soulzjd2 3 жыл бұрын

First off gratz on the knowledge gain and engine :D. Secondly I have been wondering and unable to find an answer to if the order of the triangles of a mesh matter in terms of speed? Like imagine a flat mesh terrain/grid, and removing a quad/two triangles and adding in say a tree that fits the hole left behind. Would adding the triangles to the end of the array effect speed in some way? Or imagine the order of all the triangles was random. I know the vertex order determines the face/normal but what about the triangle order? Back info on why I am wonder is simply put I am thinking about creating a map using tiles but combining or adding the meshes together and so the order of the times might not line up cleanly. Even if optimizing triangle order helps the gpu I don't want to spend time fixing my mesh if the gpu already optimizes incoming meshes since im sure its likly faster lol

Further compression could be achieved by storing colors as references so you don't need to replicate the rgb val for every item.

@josephvargas7806 2 жыл бұрын

New to graphics dev to. Not familiar with wgpu-rs. Tinkered with gl and ash crate with rust. Maybe a solution could be adding more render data in a single draw call using batch data calls as much as possible? My understanding is that each cpu call to gpu has performance hit on the cpu side, so focusing cpu multitasking solely on gathering data for a single batch gpu call might do the trick. Still learning. Not sure how multitasking works on the gpu side yet. Also not sure if you have backface culling enabled. Significantly reduces the amount of drawing the gpu has to process. Interested in how well this works for ya!

@Ian-sm9uv 3 жыл бұрын

To add some additional compression, you could find repeated blocks and have a repeat type block that indicates the previous block is repeated N times before the next block is placed. this would drastically reduce the size of your chunks depending on how random the block distribution is. for chunks with lots of contiguous blocks you could save a ton of space. even if the distribution is highly variable, it can only have smaller or equal storage size than storing every block.

@reasonnotfound 3 жыл бұрын

For runtime he could probably omit the position. Currently he uses 6 bits for each axis, if he stored all the blocks in a chunk and retrieved position using indexing, he would have to store even empty space, but each block would have 18 bits less (good for cache). Chunks that are all empty could be ommited. Not sure why the normal thing, I would just check if there are neighbors directly. Maybe it's some smart trick I am not understanding, well... Color can be palettized into just few bits, who needs all the 16 million of it anyway. For storage on disk standard compression algorithms should do the trick.

Nice video! Is it possible to use mesh instancing on the GPU? Ie. upload the mesh for a single cube, then upload the (position, colour, ...) for in all the voxels you want in a buffer to the GPU, and let it do its thing in parallel? Not sure if that would be faster - it might decrease all the CPU work you need to do for generating the meshes though? I think this is what WebRender does for rendering web pages: you just have a single box that is instanced all around and modified using shaders.

I didn't even think of doing that, it sounds on theory that this method would be faster in some aspects. But I'm exploring a lot of things that are new to me, multithreading for example. So some things I'll naturally learn over time what works best. One thing I'm speculating on is, when I get physics into the engine, maybe I actually need mesh data, not sure but that is one reason I'll stick with this method for now, many unknowns.

It was still about half the speed of Minecraft, which was disappointing. I explored using Vulkan and C++ (I'm good with C++) but I got bored and lost hope after getting stuck on how to do compute shaders with documentation that either assumes you are doing the most minimal project ever or assumes you are a rocket scientist.

You should start thinking more about how many assembly instructions are executing per line of your code and figure out how to reduce that as small as possible, sometimes is storage size, sometimes it is how you store, sometimes its the logic implemented, sometimes ita how the logic is implemented, naive implementations are always the very exact specific mentally conceptual implementation and they are always slow
