Plotter People

Plotter People is a meetup for creative coders and people interested in collaborating with robots to make art. You’ll get to talk to folks who make generative art in a wide variety of programming languages and software environments, and you’ll get access to pen plotters and the people who make them.

Plotter People #2


Chandler Abraham: 3D Rendering For Plotter Art

A common hurdle in the plotter art journey is the jump from 2D to 3D rendering. Luckily for us, plotters are an incredibly tangible and fun way to experiment with the fundamentals of computer graphics. This talk is a gentle introduction to the first principles of camera geometry and 3D rendering in the context of vector line art.

Chandler Abraham, aka @cba, is an ex-Twitter engineer, spends his days working on satellite imagery at Planet Labs.

Geoffrey Bradway: From Monotone to Greyscale

Often when we plot we have access to one color at one pressure, and you might wonder how to broaden the range of your art to get a good light and dark tones. This talk is intended to be a guide to doing exactly that and we are going to talk about the theory behind halftones, techniques people use (stippling, hatching, dithering), algorithms you can use to plot, and some examples that showcase this.

Geoffrey Bradway, aka @marchingcubes, will also be showing what the finished piece looks like in the Plotter People gallery!
