<h2><a href="https://github.com/arcadeperfect/bevy_vaporwave">Github</a></h2>
<br>
<p>Side project to learn the basics of wgsl and develop a look for my <a href="https://alexharding.ooo/posts/Rustroneer/">main Bevy project</a>.</p>
<br>
<p>The code is pretty garbage. I doubt I will continue work on this, but I will roll what I learned into the main project and hopefully it will be better that time. If you're intetested though the repo is public.</p>
<br>
<p>Features:</p>
<ul>
<li>Arbitrarily define edges to render, not render every triangle </li>
<li>Varying colors per mesh, no textures</li>
<li>Optionally "Solid" wireframe, ie it occludes its own back faces and objects behind it</li>
<li>Outline for silhouette when visible edges are sparse</li>
<li>Support gltf animation</li>
</ul>
<br>
<p>I developed a simple workflow with Blender which allows you to mark edges for rendering, paint vertex colors and store the data in a custom gltf attribute (see video below). It isn't great but it does the job. The blender files and a python script are in the repo. Bevy then builds a mesh out of line primitives for the wireframe and uses the original mesh for a fill. The mesh is duplicated, dilated along normals and pushed backwards in clip space by a shader to create the outline.</p>
<br>
<p>Issues:</p>
<ul>
<li>Wireframe thickness cannot be set because this is not supported by wgpu line primitives</li>
<li>Clip space method for outline isn't ideal, a stencil buffer approach would be better but I couldn't work out how to do that with wgpu / bevy render pipeline</li>
<li>Assets are post processed in a system triggered by SceneInstanceReady events. Something that ties into Bevy's async asset loading would be much better </li>
<li>The mesh building algorithm is very slow with large meshes</li>
</ul>
