This is the code for a November 2017 net magazine tutorial, Stylized Wireframe Rendering in WebGL. Check out the article (when it's released) for more details.
The code here uses barycentric coordinates to create stylized wireframes in ThreeJS and WebGL. Some features of the code and its shaders include:
- Alpha to Coverage for crisp alpha cutouts and depth testing with Multisample Anti-Aliasing
- Thick and anti-aliased single-pass wireframe rendering
- Basic support for animated line dashes
- Inner edge removal to render quads instead of triangles
- A few other effects, such as noise, tapered lines, dual strokes and backface coloring
