Quite handy if you've just landed a job in a somewhat unusual 24hr bookshop.

(Explanation: https://en.wikipedia.org/wiki/Mr._Penumbra%27s_24-Hour_Books... - the protagonist writes a 3D visualisation in Ruby. It's a good read.)

Ha hahaha. Sure enough, I clicked this story b/c I was like, "Oh hey! That matches my interests!" ;)

You should show PNGs of the example renders, maybe APNGs / GIFs of rotation or zooming. That would make me feel like downloading it more, if it looked neat

I've added a few GIFs to the README now.

Oh my, is the code for the tank example published anywhere? I didn't see anything in the examples directory but I could have missed it.

Edit: Looked through your repositories and here it is! https://github.com/jellymann/mittsu-tank-demo

As an aside, mittsu (三つ) is the Japanese word for counting three things: https://en.wikipedia.org/wiki/Japanese_counter_word

Mitsubishi means "three water chestnuts" and explains the three-rhombus logo: https://en.wikipedia.org/wiki/Mitsubishi#History

GP is correct. It's right there in the wikipedia link.

holy moly, I have forgotten more than I realised :( embarrassing

Interesting. I started my own work on something exactly like this, before giving up after realizing how poor the Ruby opengl perfomance is / how difficult proper graphics rendering can be. Nice to see some more graphics work being done with Ruby.

Sorry if this is an ignorant question, but does it run in the browser?

No, it runs as a desktop app in a native window.
