Caleb Johnston

Hello! This my personal website and blog. I'm an engineer and technologist with professional experience in real-time rendering, embedded systems, and systems integration. My career also includes several years in management at startups, consultancies, and large enterprises. I love learning and using numerical linear algebra, systems dynamics, and new rendering techniques. My personal heroes are Buckminster Fuller, Richard Feynman, and William Gibson.

Professional Work

I'm currently building holographic displays as an engineering team lead at Looking Glass Factory in New York. I previously worked as a software engineering leader and manager at Amazon and Intersection. I'm especially proud of building permanent interactive installations for AT&T's executive briefing center and the Edward Kennedy Institute for the United States Senate. But I kickstarted my career in New York working as an interactive developer for digital agencies, including R/GA, AKQA, Razorfish, and HUGE.

Personal Projects

Over the years, I've started dozens of personal projects (but rarely finished them).
Here are some of my favorites:

• Automaton is a text-based game that I started a couple years ago
• Scenegraph cinderblock is a custom scene graph extension for Cinder
• A B-Spline patch implementation which is also built using Cinder
• The Fluid Dynamics Library is my implementation of Robert Bridson's fluid solver
• PixelPipe is a simplified software implementation of an OpenGL driver

I have lots of opinions that I freely share in person. But sometimes I write them down too.
