Despite the lack of a functional debugger, I decided to give Go a shot anyway. This may well be a result of my lack of practice with the language, but I found it pretty off-putting, despite how much I like the goals of the language and a lot of its design decisions.

It turns out that Go does quite well on these constraints. But for the desktop platforms and Android NDK, which sufficesit works out of the box. Just as importantly, the Go compiler produces a single statically-linked binary, which is exactly what I want.

This means you can, for example, implement a struct with a flat memory layout, like so:. This gives you a lot of control over memory layout. Also, as in C, you can safely take pointers to the middle of structs and arrays.

This is an underappreciated property of Go that unlocks a lot of useful tricks and optimizations. Well, in addition to cache coherence, you can also use it to roll your own pool allocators.

Game developers are legendary for their fear of garbage collection, and often for good reason. Having the ability to dramatically reduce the amount of garbage you generate, without losing memory safety, changes everything. This article gives a good example of how this can play out in practice. Go makes interfacing with C interfaces trivial. It also offers some useful tricks for improving the semantics of some libraries, without introducing any overhead.

A common case is resource loading, which when implemented inefficiently is the bane of many a gamer. Imagine, for example, a simple MeshDef type, which represents the vertices and indices for a triangle mesh, and needs to be loaded quickly from disk:.

Now you could just implement this by reading the verts and indices from a stream, fixing up endianness for the uint16s as you go.GitHub is home to over 40 million developers working together to host and review code, manage projects, and build software together.

The goal here is to create a graphics engine in the style of minecraft, with total control of terrain generation. For starters the goal currently is not to have destructible terrain. It should be usable as a basis for participation in GameJams. Along the way I want to learn:.

Search this site. Vox - Downloads. Additional Links Official Vox Site. These tutorials and guides are what I wrote as I made my own voxel engine which later changed into the game Vox. If you are interested in learning about voxel engines, or want to make your own voxel game then these articles and tutorials should help you achieve this. Please be sure to checkout Vox, the game I am making that is based on the code contained on this site.

This series of guides and tutorials is going to be on the topic of making a voxel engine. Voxel information The main purpose of these guides is to introduce you to voxel engine concepts and ideas which help you produce an engine that satisfies a number of goals. Making a good voxel engine takes time and effort, but luckily the process fits nicely into an iterative development cycle.

It is easy to start with something very basic and slowly build up to a more complex and thorough voxel engine with lots of little steps.

The more complex tasks such as chunk management or collision detection can be thought of as singular problems and tackled individually as sub-tasks.

These guides are going to assume you are familiar with 3D graphics and 3D math and have already done some programming in a 3D environment, such as OpenGL or Direct3D. Most of the rendering code for these guides will be written using my own personal rendering library, which is essentially a wrapper around OpenGL, where I abstract away the OpenGL calls or group together common OpenGL functionality into a single renderer function, to make the game code easier to manage.

I am currently using the voxel engine I have created to make a brand new voxel based adventure, RPG and creation game called Voxinformation about this can be found at IndieDB. There are many different tricks you can do with voxel data that allows you to achieve these goals, some are efficient programming tricks, others are rendering optimizations.

Once you get used to visualizing the simple voxel data there are many fascinating things you can achieve, and hopefully these guides will show you the mysteries behind a good voxel engine. Below are the rough steps that I have followed when making my own personal voxel engine:. General Articles.

So, this morning I was playing voxelstein 3d and got on a voxel kick, I started working on a voxel engine in Unity and was surprised at how great the performance was.

There's still some optimizations I can do. But I wanted to see what people thought or maybe get ideas for things I should add to the engine.

Some obvious things would be water behavior, caves to the terrain generator, etc. But I don't want it to just be a "Minecraft-like" engine, I want it to be more general than that. It takes a while to start up though, virtually all of that time is generating the collision mesh, which I still need to optimize better. I had one method that did it about 7x faster, but unfortunately it stopped working now leaves strips of "empty" mesh and I'm not sure why.

So for now it's the "slow but works" version. Once it starts it should run fine, I get about fps, depending on how much of the scene I'm looking at. Cheers, Will. Last edited: Aug 15, SolInvictusAug 10, Joined: Mar 9, Posts: Totally sweet, nice terrain man. Random Indie.

As for additions, I think having a voxel to physics cube to voxel system would be handy. Say you are looking at a wall and you have some kind of explosive. You set it on the wall and rather than the blast simply destroying the material it actually flings debris outward that reacts to the world and when it comes to a stop is 'revoxelized'.

Another idea is that if you're not dealing with infinite terrains which makes this a hard problem you could add some kind of structural integrity checker. You could check if a block has a path to ground the bottom of the world? This could be extended so that if there isn't a good enough say it's too long or some such path to ground it collapses as well. Would be useful for knocking down buildings.

I have been working on a voxel game for some time now, but all that I have really accomplished was the main menu and an Item system. Now its time to make the voxel engine. What I know is that there are different methods for voxel engines, they all begin with rendering a single cube, and Perlin and Simplex noise can be used to randomize terrain generation.

If anyone could point me in the correct direction, most appreciated.

I will be checking back at least once a hour incase someone feels this thread is dead. I'm not entirely sure what you are asking, if you are asking how to make simplex noise, implement it in a voxel engine or how to start making a voxel engine.

If you are asking how to start making a voxel engine I would recommend practising with quads first 2D version and focus on getting an understanding for the theory. Once you are happy with your understanding you should focus on the voxel class one cube - it is very important to learn as much as you can from it, and then add more so you can optimize rendering as much as you can, such that hidden faces are not rendered and even vertices are shared, voxel engines can be the most wasteful renderers if not optimized!

EDIT: Optimization can be done through many methods, The first and most important is hidden face removal, this involves removing the faces of voxels that are touching which will mean you will need to check of a voxel exists on any given side of any voxel before rendering that face e. Next is the rendering method, do not render each face or each group individually, group them so they can be rendered faster, this can be done by using display-lists or the more technical VBOs, these ensure the data is in the GPU or the data can be given to the GPU faster, For example Minecraft groups them in chunks of huge 16x16x groups and uses display lists.

If you really want to reduce every single vertex in memory you can also consider using strip drawing methods in OpenGLthese will require you to define certain vertices at a certain time in rendering but allow you to reuse a vertex for multiple faces. Next would be understanding simplex noise, I can relate to there not being much material online for noise generation algorithms, unfortunately I cannot link material that I used as that was years ago.

You can implement your noise algorithm in the 2D version to prove it works in a simpler environment and then copy it to the voxel version. Typical usage would be to use the values as heights in the terrain e. I would recommend using Unity.

The engine is already made and you can add menus and titles with just a few lines of code. Good luck! Learn more. Where to start with voxel engine? Ask Question. Asked 6 years ago.
