Sneak peek of Rayven
I would like to give you a preview of my new project that I'm really excited about - Rayven. It renders 3D scenes as if they were line-hatched by hand:
I've had this idea for a while and after researching, I found three projects that became my inspiration: Michael Fogleman's ln, Kushiro's Hatch Lines Shader and Piter Pasma's Rayhatching.
Although it's far from finished, I want to share my progress. Once I'm satisfied with it, I plan to open-source it and write another post to show you under the hood.The first text render #
The first step was to build a basic 3D renderer with objects defined as signed distance functions. It used text to render the scene and it was based entirely on Theia Vogel's great article. Better ray-tracing and the first vector renders #
With proper ray-tracing in place, I began figuring out how to hatch a scene using vector lines. I started simple, using only vertical lines (image on the left). Then, I gradually worked my way to using vector fields (image on the right). Tweaking vector rendering #
