This page is my personal collection of highlights from GDC 2014. I was not able to attend in person, so I had to rely on Twitter to get updated. The immersion was not perfect, but some of the thrill was definitely carried over. So here it goes (in release order): Weiterlesen

Ego mecum conjungi …
So out of a whim I just embarrassed myself and tried to write in (probably wrong) latin that I joined twitter. You can follow me under: @aries_code.
If you wonder how this came about, this was my train of thought:
- Twitter has something to do with birds
- Birds have fancy latin species names
- The species name for Sparrow is Spasser domesticus
- This doesn’t sound too fancy …
- How do you say ‘I joined twitter’ in latin anyway?
But then I discovered that I am onto something: According to one argument, the brand name of Twitter should have been ‘Titiatio’, had it existed in antiquity. And according to another argument, latin should be an ideal twitter language, because it is both short and expressive.
But I digress. If you are into computer graphics, then you know of Johann Heinrich Lambert, the eponym of our beloved Lambertian refelectance law. The book where he established this law, Photometria, is written entirely in latin—now this is hardcore!
So, now you know what to do if you want to stand out in your next SIGGRAPH paper …
Yes, sRGB is like µ‑law encoding
I vaguely remember someone making a comment in a discussion about sRGB, that ran along the lines of
So then, is sRGB like µ‑law encoding?
This comment was not about the color space itself but about the specific pixel formats nowadays branded as ’sRGB’. In this case, the answer should be yes. And while the technical details are not exactly the same, that analogy with the µ‑law very much nails it.
When you think of sRGB pixel formats as nothing but a special encoding, it becomes clear that using such a format does not make you automatically “very picky of color reproduction”. This assumption was used by hardware vendors to rationalize the decision to limit the support of sRGB pixel formats to 8‑bit precision, because people “would never want” to have sRGB support for anything less. Not true!I’m going to make a case for this later. But first things first.
