Voxel game engine tutorial

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:. Search this site. Let's Make a Voxel Engine. Report abuse. Page details.

Voxel Game Engine Tutorial I got some time this weekend to spend with VoxelJs, and it is a lot of fun, but it is new and I wanted to share some of the things I learned as I was getting up to speed on the engine. Here is a step by step tutorial on creating a flat world.

The Setup Install NodeJS Install browservefy - npm install browservefy -g Browservefy will be our web server that will serve our voxel game, without having to create a dummy html page.

Although most people were introduced to voxels through Minecraft, the technology has been around for many years. In the early years a common use was medical scanners, and optimizing it was a matter of saving minutes for every zoom or rotate a doctor made to a scan.

A lot of research has been made into rendering voxels, and there are papers out there that detail many different techniques. Today we use it for games, and we are optimizing in the ms range. Lets just jump straight in and tackle this one first. Lets assume you are using voxels in a game such as Minecraft, so you need to store 1 voxel for each 1x1x1 meter in the world. If you are storing a world that is x, y, z 10x10x10, and each voxel is represented by one byte 8-bit then you need bytes of storage.

If each voxel is one int bit then you need bytes of storage. You would probably want a much larger world than 10x10x10 voxels, so you may need to balance the number of voxel types you support with how much memory you can use. If your world is 1. Clearly this can be a bit much to load all at once on an average computer.

Even if you size down your world, anything bigger than a few meters means you run into memory access problems. This is because of how modern computers work. So splitting the world into smaller areas chunks and loading only the chunks required will make the demand for RAM a bit lighter. If you want to look 10 chunks voxels in any direction radius that is 20 chunks in each axis.

If you ever worked on bitmap images you will recognize the calculation, only here it is in 3D. Well, several reasons. One being speed, another being easy serialization.

Most likely, your organization already uses cloud providers like Microsoft Azure or Amazon Web Services. The Voxel Farm platform extends the benefits of these cloud solutions and applies them to spatial and temporal datasets. You do not need to set up servers or devise scaling strategies for increased storage and processing. The Voxel Farm platform takes care of this for you.

Use your spatial data from multiple rendering systems and platforms.
