I wrote one of those once! It was a nightmare morass of one-pixel errors. Maybe there was some clever simplification I missed that would have made it all easy, but these days I use…

I like stb_truetype myself. It's C so you'll have to bind it if you're using any other language, but it's a lot simpler than Freetype. (Less features too, but it'll take a .ttf and…

The geometry may be flat, but relationships between objects are still arbitrary, so light can still hit things from any angle. Try as you might, you can't escape curves. ;) That ar…

Whoops, yeah, you caught me. As I handwaved in the post, there's a little bit of implementation detail in the real code that I removed to clarify the algorithm. Fixed now, thanks.

ryg has been at RAD Game Tools for a while now, and mentioned yesterday on Twitter that he's been doing contract work on Valve's hardware experiments. [1] [1] http://twitter.com/#!…

Especially of interest to HN readers is Part 3, which is about the economics of streaming anime - the ad-revenue numbers they present are shockingly low.

Yeah, this article seriously rubs me the wrong way. The tone throughout is "Rich Nerd Buys Cool Toy." And in that context a lot of the talk about the clock's "greater purpose" come…

It's not just that - even when we're talking Warren Buffett here, the scale of the US govt is totally different. Buffett's entire fortune ($50B according to Wikipedia) would only c…

This is the article that introduced me to monofur, which I dearly love even though it seems fairly unpopular. Take a look[1] and you'll either think that lowercase L is a terrible …

Uncharted uses a DSL for gameplay scripting. The compiler is implemented in Racket. You can see what it looks like in Jason Gregory's 2009 presentation: http://www.gameenginebook.c…

That doesn't match Amazon's behavior. If they thought they could optimize prices for the benefit of app developers, I would expect them to offer the option. "Is setting your price …

The distinction I'm trying to make is between parsing the text once (using a compiler-like utility which is separate from the game runtime) then shipping the "compiled" binary form…

But using JSON would have required parsing text in order to load the file. That's fine in a lot of domains, but games often have to load megs and megs of data in a very short time.…

This always makes me think of Isaac Asimov's classic essay, "Forget It!" in which he gets a hold of a hundred-year-old math textbook and writes about what's in there that isn't tau…

A good university is the best place in the world to meet other programmers. Go to the best school you can - once you're there, you'll be shocked how fast you improve when you're su…
