How to Choose Colours Procedurally (Algorithms)

How to Choose Colours Procedurally (Algorithms)
Changing the colours of art can be a great way to increase the amount of content in your game, and add variety and richness. It is relatively easy to implement. What is not always as easy is to get a set of colours that looks nice. This article gives some ideas for choosing colour palettes that look nice. A few things about colour Colour is surprisingly complex. Although you don’t need to know all about the physics, biology, and psychology of colour vision, it is useful to have some background information (which you can find references to at the end of this article). For palette choosing, there are a few important points. Digital colour theory differs considerably from theories based on pigments (or chemicals, or metals in crystals). Vector distances in RGB and many other colour models don’t correspond to differences in perception. Edit: Turns out I have fallen prey to the very thing I talk about. Brightness These greys are equally spaced. Hue differentiation. Colour harmony theory. 1. 2. 3.

Why YouTube buffers: The secret deals that make—and break—online video Lee Hutchinson has a problem. My fellow Ars writer is a man who loves to watch YouTube videos—mostly space rocket launches and gun demonstrations, I assume—but he never knows when his home Internet service will let him do so. "For at least the past year, I've suffered from ridiculously awful YouTube speeds," Hutchinson tells me. "Ads load quickly—there's never anything wrong with the ads! Hutchinson, a Houston resident who pays Comcast for 16Mbps business-class cable, is far from alone. Why does online video have such problems? But cynical types who suspect their Internet Service Providers (ISPs) intentionally degrade streaming video may be right as well. These business decisions involve "peering" agreements that Internet companies make to pass traffic from one to another and negotiations over caching services that store videos closer to people's homes so they can load faster in your browser. The negotiations can lead to brinksmanship and bad blood.

Essential Math for Games Programmers As the quality of games has improved, more attention has been given to all aspects of a game to increase the feeling of reality during gameplay and distinguish it from its competitors. Mathematics provides much of the groundwork for this improvement in realism. And a large part of this improvement is due to the addition of physical simulation. Creating such a simulation may appear to be a daunting task, but given the right background it is not too difficult, and can add a great deal of realism to animation systems, and interactions between avatars and the world. This tutorial deepens the approach of the previous years' Essential Math for Games Programmers, by spending one day on general math topics, and one day focusing in on the topic of physical simulation. Topics for the various incarnations of this tutorial can be found below. Current Materials Slides The latest available versions of the slides for the math tutorials at GDC 2015 are as follows: Past Materials Core Mathematics

samsquire/ideas Kim Jong-il's Sushi Chef Kenji Fujimoto: Newsmakers The sushi chef was leaving his apartment when he noticed the stranger outside. He could tell by the man's suit—black and badly made—that he was North Korean. Right away, the chef was nervous. Even in his midsixties, the chef is a formidable man: He has thick shoulders, a broad chest; the rings on his strong hands would one day have to be cut off. But he'd long since quit wearing his bulletproof vest, and the last time a North Korean made the journey to visit him in Japan, a decade ago, he was there to kill him. The stranger came closer. "This is about your family," the stranger said. "Go away," the chef told the man, and without another word the man disappeared. A month later, in early July, another North Korean in a black suit came to the chef's door. "Come with me, Fujimoto," the man said, and together they went to a bare-bones hotel near the Sakudaira train station. Luring people back to North Korea to be executed or dispatched to gulags was a favorite trick of the regime.

Glass The hardware looks much better in person than I expected. In fact, I would even say it looks good. The industrial design is solid, and though it is being manufactured in small batches, it has the build quality you might expect from something being mass-produced. Glass is very clearly an early “alpha” product, and it’s only being sold to very few developers and invitees, so my thoughts below will focus mainly on the design challenges facing ambient computing in general and to point out some things I hadn’t thought about before actually wearing Glass. I was standing outside on a sunny day when I put on Glass for the first time. The software is very rudimentary, which is fine considering the “alpha” nature of the device, but I expected it to be smarter. While some of the human <=> computer interface design challenges facing ambient computers are obvious in theory, many of them are very hard to identify until you actually experience using the device as part of your life.

Jurassic Hack Jurassic Hack Jurassic Park est sans aucun doute l'un de mes films préférés. D'ailleurs vous souvenez-vous de cette scène d'anthologie où Samuel L. Jackson (aka Ray Arnold) essaye de redémarrer le système piégé par Nedry ? Et bien ce que vous propose Jurassic Systems, c'est de revivre vous-même ce moment. Sachez aussi qu'il y a une fonctionnalité cachée dans le système... je pense que je l'ai trouvé (une photo) mais pas sûr. Source Vous avez aimé cet article ? The inside story of ESGN's fall In early 2013, a 32-year-old Brit named Rory Dickenson moved to Berlin to work a pair of short-term freelance jobs. But he hadn't been there long when he found an opportunity he couldn't ignore. A human resources service put Dickenson in touch with a company calling itself the Esports Global Network. Dickenson was pretty familiar with the growing competitive gaming, or esports, industry, and he could easily guess what this new online video network might be about. He knew about The International, a tournament for the game Dota 2 that the previous year had boasted a prize pool of $1.6 million. And he knew of the success that competitive gaming had seen in some countries, like Korea, where pro gamers were treated the way professional athletes are in other parts of the world. On October 2013, he went to the group's offices for an interview. From the outside, ESGN appeared to have everything going for it. In Korea, StarCraft is more than just a game with a rabid fanbase.
