I am writing a 3D renderer that would render 3D models as if they had been drawn in halftone. Feature-wise I need nothing fancy - no colors, just pure 3D geometry and basic lighting like here: Image credit: https://blenderartists.org/forum/showthread.php?438820-Suzanne-Sketch
- I have written a basic 3D renderer in the past, however, I am really inexperienced when it comes to shaders (again, I do know basics) and I have absolutely no idea where to start with this.
- The example image has been created in Blender, but I am writing my custom renderer.
- This is not a duplicate of "How can I make a shader effect that looks like a lightly shaded pencil drawing?", as my input is a 3D model, whereas the OP in the linked question used an image.
