CHIP-8 in Common Lisp: The CPU

Rediscovering Quaternions
How do we represent a rotation in 3 dimensions? This is a surprisingly deep question, and one we can learn a lot from. Our goal will be to “rediscover” quaternions from first principles, building them up by exploring different representations and fixing the failures along the way.

Myst: the Drawbacks to Success
Robyn Miller, one half of the pair of brothers who created the adventure game known as Myst with their small studio Cyan, tells a story about its development that’s irresistible to a writer like me.

Let's Play Ancient Greek Geometry
Today I’m releasing Let’s Play: Ancient Greek Geometry . It’s a Compass and Straightedge tool/puzzle game written in JavaScript. I’ve always thought Geometric Construction felt like a puzzle, so to me this pairing was quite natural. Compass and Straight edge is a technique for constructing shapes out of circles…

Adventure Games and Eigenvalues (2017)
Do adventure games have dead ends? The author of The Teeny Tiny Mansion proves the absence of dead ends in that game via formal verification (in particular, with the help of the cbmc model-checking program ). Here I’ll demonstrate how to prove the same thing via Markov theory. The Markov approach requires more…

Lightmap Compression in the Witness
In my initial implementation of our lightmapping technology I simply stored lightmap textures in RGBA16F format. This produced excellent results, but at a very high memory cost. I later switched to the R10G10B10A2 fixed point format to reduce the memory footprint of our lightmaps, but that introduce

It was all so…
