Similar to phones and computers, Chromebooks also support a clipboard. The last 5 items that you’ve copied including images and text will be saved in the clipboard. You can access it by pressing the Search + V keys on the keyboard. Moreover, any screenshot that you take on Chromebook is automatically copied to the clipboard. This is an example of what we'll have by the end of this article TL DR: The best way to have MagicaVoxel models loaded into a Three.js scene is to export. There is currently no reliable library for loading. vox files (the default format used by the program), but exporting. Also, don't worry about your voxel palette and materials, as both are also exported by MagicaVoxel. My goal here is to learn (and share the knowledge of) how to load MagicaVoxel models into a Three.js scene. I want it to be efficient (i.e., I don't want lots of cubes with hidden faces) and I'd like to be able to see all the materials correctly displayed as well.įor some strange reason (at least for my present self), I first decided I should try directly loading. I googled for an existing library to do that because I didn't want to spend time figuring out how to parse models into meshes right now. This library, but it's been about an year and a half since it was last updated. Nevertheless, I decided to try it, but it didn't work. The library just threw an exception when I tried the sample code in the readme. It then occurred to me: why not just export a. obj file? It's a ludicrously well-known file format that's been around for ages. One of the things I was afraid was that MagicaVoxel was going to export several individual cubes that would be really bad for performance (lots of unnecessary triangles would need to be rendered). Thankfully, you will see that's not the case. to check if exported materials work as well.to confirm that exported meshes are efficient with respect to the number of triangles created.My second fear was that I was going to have a hard time trying to load all the materials correctly also wrong! MagicaVoxel merges voxels of a same object into a single mesh. Let's start with a 2x2x2 cube (.vox model here). obj and rendered in Three.js in wireframe mode: This is how it looks in MagicaVoxel:Īnd this is how it looks after being exported to. Rotate it a bit to understand how voxels were merged. Now let's make the model a bit more complex by removing one of the voxels of the cube: But how will it look if the model gets more complex? Cube with an eroded corner Every face of the 2x2x2 cube turned into a pair of triangles, proving MagicaVoxel did a good job exporting voxels into a single, efficient mesh. Notice that the object still is a single mesh, although now there are more triangles. Notice, however, that the triangle count is as low as possible for this object. Rotate it and try to come up with a better solution (i.e., with less triangles) for the L-shaped faces if you do, please don't forget to write a paper about it □. With it, users can create and export models in a very short time frame.Obj files is not the focus of this article as there are countless examples on the internet on how to do it. Overall, MagicaVoxel has all the tools that are required in a basic 8-bit editing app. These shortcuts will make the creation process more efficient. Users will find all the basic functions easy to grasp and will be able to move on to configured keyboard in no time. Even those who have no prior experience with 3D modeling apps will find it a breeze to work with. Users can attach, erase, move or paint voxels, and also insert existing patterns and basic objects as well.ĭue to its intuitive interface, the app can be navigated with was by users of all levels of expertise. There are multiple types of brushes with which users can draw various shapes. Each panel can be collapsed or expanded to give the user access to more tools or increase the space of the drawing window. It has an impressive, fully customizable interface, and the layout has been well designed. MagicaVoxel houses an impressive array of features, yet it is extremely easy to use, includes an interactive path tracing renderer and has extensive export capabilities. It comes with a rendering engine and provides you with a comprehensive set of tools to work with. A free lightweight 8-bit voxel editor and interactive path tracing renderer.
