"In summer of 2020 I bought a plotter, a robot drawing machine that holds a pen. It is only capable of drawing lines, and nothing else.
Because of this I had been focusing on vector based SVG outputs. This is a file format particularly suited for the plotter, which builds images as a collection of lines and shapes, instead of pixels, like a JPEG does.

However, I felt the urge to play and experiment with 3D SDFs and raymarching again. An SDF is a mathematical function that describes shapes, in a way that is particularly suited to raymarching. Raymarching is a technique used for raytracing, which is a technique to simulate light bouncing off these 3D shapes, resulting in a picture. Unfortunately, these techniques are mostly aimed at pixel-based rendering, so I had to get clever.

In these first two pieces I use a raster-based scribbling approach to generate scribbles of varying size, creating varying levels of brightness." - Piter Pasma

About Piter Pasma

Inspired by the possibility of math and code, Piter Pasma’s background in the competitive demoscene of the late 1990s honed his expertise in writing algorithms in their most efficient form. He is known for using mathematical functions to describe three-dimensional generative scenes, executed using his "rayhatcher" algorithm, which creates plottable line art, and uses a minimal amount of code. Pasma enjoys encouraging others to create by organizing Genuary, an annual event where artists create daily pieces according to 31 carefully selected prompts. Pasma is based in Groningen, the Netherlands, and has won multiple prizes for his real-time audiovisual artworks contained under 4 kilobytes.
