svg-sdf-art

takes a SDF ray marching scene from a fragment shader and does a stylized SVG render, for my pen plotter machine

the goal is to quickly and easily create a nice scene with an SDF in the fragment shader (lol) and then convert into a pen plotter-friendly SVG from it. Also, add some details that attempt to give depth to volumes and a sense of distance.

this works by first rendering the SDF in a shader in 3 different versions. First, the scene is rendered using surface normals. Second, the scene is rendered with distance information. Third, the scene is rendered based on unique objects. With these three buffers, I perform marching squares in various ways to highlight the silhouettes and faces of shapes. Last, I draw random lines around the scene which are meant to give a sense of shape, depth and distance to objects in the scene.

the final export is an svg file for an A4 paper
