Introduction to Position Based Fluids | PhysXInfo.com - PhysX News. Many of you may have already seen an impressive real-time destruction and fluid simulation demo from GDC 2013. Update: Position Based Fluids explained Update #2: Introducing NVIDIA FLEX: unified GPU PhysX solver We won’t talk about fracturing technology today, instead, let’s focus on the new fluid simulation algorithm, presented in the demo – it is known as Position Based Fluids. Position Based Fluids is a way of simulating liquids using Position Based Dynamics (PBD), the same framework that is utilized for cloth and deformables simulation in PhysX SDK. Because PBD uses an iterative solver, it can maintain incompressibility more efficiently than traditional SPH fluid solvers.
It also has an artificial pressure term which improves particle distribution and creates nice surface tension-like effects (note the filaments in the splashes). Finally, vorticity confinement is used to allow the user to inject energy back to the fluid. 15 Responses to 'Introduction to Position Based Fluids' How to Read and Write in 1337: 12 steps. Edit Article 1337 SamplesReading and Writing in 1337 Edited by Thief, Battlecruser9292, Ben Rubenstein, Colin Marchon and 95 others LEET (1337) is a written language or cipher used in online gaming, e-mails, text messaging, tweeting, and other electronic communication.
The root of the term "leet" is the word "elite"--translated as 31337--and 1337 was initially developed as an exclusionary language: a way to encode text so that messages could only be read by the initiated. The defining characteristic of 1337 is substitution of symbols and numbers for letters (for example, in the term "1337," 1=L, 3=E and 7=T), but the language has also developed to include intentional misspellings, phonetic spelling, and new words. If you want to familiarize yourself with 1337, or if you're just curious about it, this article will explain the basics of how to read and write in this ever-changing language.

The Internet map. Kogan Hates IE7 So Much It’s Imposing A Tax On All Shoppers That Use The Browser. Ruslan Kogan may not be a known entity in the U.S., but the Aussie entrepreneur is a pioneer of online retail in Australia and happens to be the country’s wealthiest self-made person under the age of 30. Oh, and he also founded Kogan.com, a a manufacturer and direct retailer of consumer electronics that’s projected to hit over $100 million in sales this year. But, more importantly, the guy likes to be controversial and, when things suck, he’s not afraid to say so.
Which is why Kogan announced via his blog today that his company is implementing what he believes to be “the world’s first ‘Internet Explorer 7 Tax.’” It may sound like a joke, but Kogan is totally serious. He doesn’t like IE7. Why? From here on out, Kogan.com will be imposing a 6.8 percent tax on all products purchased by anyone so brash, with such appallingly low standards as to be patronizing Kogan.com by way of IE7. No he’s not on a crusade against Microsoft or Internet Explorer in general, he just wants people to update.

Military needs during World War II caused a great thrust forward in the evolution of computers.
ENIAC Is Born Programs: Change The Software, Not The Hardware. How 3D Graphics Work. Looking at the number of information bits that go into the makeup of a screen only gives a partial picture of how much processing is involved. To get some inkling of the total processing load, we have to talk about a mathematical process called a transform. Transforms are used whenever we change the way we look at something. A picture of a car that moves toward us, for example, uses transforms to make the car appear larger as it moves. Another example of a transform is when the 3-D world created by a computer program has to be "flattened" into 2-D for display on a screen. Let's look at the math involved with this transform -- one that's used in every frame of a 3-D game -- to get an idea of what the computer is doing.
The first part of the process has several important variables: First, we calculate the size of the windows into the imaginary world. In the example below, you see an animated sequence showing a walk through the new How Stuff Works office. 20 Things I Learned About Browsers and the Web.

70 Things Every Computer Geek Should Know. | Arrow Webzine. The term ‘geek’, once used to label a circus freak, has morphed in meaning over the years. What was once an unusual profession transferred into a word indicating social awkwardness. As time has gone on, the word has yet again morphed to indicate a new type of individual: someone who is obsessive over one (or more) particular subjects, whether it be science, photography, electronics, computers, media, or any other field.
A geek is one who isn’t satisfied knowing only the surface facts, but instead has a visceral desire to learn everything possible about a particular subject. A techie geek is usually one who knows a little about everything, and is thus the person family and friends turn to whenever they have a question. If you’re that type of person and are looking for a few extra skills to pick up, or if you’re a newbie aiming to get a handhold on the honor that is geekhood, read on to find out what skills you need to know.
