![]() ![]() 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. MagicaVoxel vs VoxelShop vs Goxel - Slant. 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 □. A mostly javascript-centric resource / links list on procedural content generation (PCG).Obj files is not the focus of this article as there are countless examples on the internet on how to do it. Please submit all PRs and issues on our GitLab page. An open world, open source voxel RPG inspired by Dwarf Fortress and Cube World. Video playback Effects/Filters (DirectX. We have a list of the top alternative voxel editors to MagicaVoxel for creating voxel art for graphics as well as games. A collection of shaders for MagicaVoxel to generate geometry, noise, patterns, and simplify common and repetitive tasks. DecemReviews If you want to try a different editor outside of MagicaVoxel there are quite a few choices to choose from. vox files (the default format used by the program), but exporting. MagicaVoxel is a free, open source software package that provides simple, yet surprisingly powerful 3D modeling capability. Also, don't worry about your voxel palette and materials, as both are also exported by MagicaVoxel. The maximum dimensions for one voxel is 126 x 126 x 126 (since May 2020 it is 256 x 256 x 256). The included palettes are based on a 256x1 single row PNG, with the data starting at the right side of the image. Previously known as Super Look Up Tables My goal here is to learn (and share the knowledge of) how to load MagicaVoxel models into a Three.js scene. A city-themed collection of over 400 blocky models you can remix or use outright in your own works. 2D Lit Sprite shader for 2.5D art style using an orthographic camera □ A heavily customizable, fullscreen-compatible crosshair overlay for ReShade A generic post-processing injector for games and video software.
