Voxel.js: Minecraft-like Browser-Based Games, But Open Source 110

Posted by timothy from the blocking-things-out dept.
Paul Fernhout writes with a snippet from Joystiq: "Voxel.js is a new open-source project designed to allow anyone to create 3D games that run directly in a browser. Created by Max Ogden and James Halliday, Voxel.js is based on JavaScript and WebGL, and makes it relatively easy to build Minecraft-like games that play in browsers like Chrome." Paul adds a link to this interview with Max Ogden about the creation of Voxel.js in 22 days. The main site is at Voxel.js.

      Wait, you want everything to run on a common software platform? How revolutionary. We could call it "Doorways", because the browser would provide a path to see into the possibilities. We could have a common add-on called "Glimmer" that provides additional functionality.

      I can't picture any problems with such an approach.

      First, they say "Chrome version 23 or above or Firefox version 17 or above are recommended." So, you can try either.

      I had problems using Voxel.js in Firefox 18 on the Mac, so I downloaded Chromium (the open-source fork of Chrome) from FreeSMUG , and Voxel.js ran fine it it. It was actually snappier than Minecraft on my machine, but that may just be because of a smaller world?

      I feel I'd probably rather download Chromium once and then surf to web pages than download a Java application like Minecraft and deal with all sorts of issues when trying to use Minecraft add-ons (given Minecraft has not prioritized supporting community add-ons). It has been a pain to manage lots of incompatible Minecraft add-ons (my wife even wrote a tool to help our kid deal with that). Also, when you download Minecraft addons, they presumably with full permissions and so could do anything to your system like read or delete files. I presume that web pages in Chromium are much more limited in what they can do (even though I have heard about theoretical WebGL exploits).

      Here is a pre-built download link for Chromium if Mac users need it:

      Or people can build it from source:

      It would probably be fair to say WebGL is not that well supported everywhere. I had problems with it in Firefox as above. Still, it seems to me like this group is trying hard to use open standards with JavaScript and WebGL, so I'm not sure your criticism is fair in that sense. WebGL is supported by multiple browsers, but probably just not very well yet:
      http://en.wikipedia.org/wiki/WebGL [wikipedia.org]

      Still, give it time, and I expect WebGL (or something similar) will run most anywhere.

      Anyway, this generation may be "nuts" in their own way, true. :-) The question is, is the "nuts" of a bunch of people across the planet getting together virtually to write free and open source software (for shareable virtual worlds of abundant virtual resources) more "nuts" than a bunch of people getting together to give us, say, the "Cold War" and the artificial scarcity of software patents and endless copyrights etc.?

    • The goal of Minecraft et al. is to provide very large (or sometimes truly infinite worlds). To achieve this you have to use extremely efficient memory storage. I don't know the actual figures but I assume Minecraft stores one or two bytes per voxel, which are approximately 1 cubit-foot, so a very efficient representation.
      This simply isn't enough memory to store more then a few shapes (though a sphere dose seem a good choice).

        But that's not really all that efficient of a storage representation. By far, most of the blocks in the game are of two main type - air and stone - and almost every structure in the game is composed of some volume of mostly homogeneous blocks with perhaps smaller volumes of homogenous blocks suspended almost vacuole-like inside it - It might well be possible to more efficiently describe the landscape using the surfaces rather t
