Artificial lens flare is an important part of making certain computer generated scenes look realistic, but up to this point creating realistic lens flare has been a task that requires a good deal of processing power. Now, researchers have come up with a way to simulating lens flare quickly and accurately, taking into account a large number of physical factors that cause the phenomenon:
The underlying model covers many components that are important for realism, such as imperfections, chromatic and geometric lens aberrations, and antireflective lens coatings.
The video above discusses how the technology works, and also touches on the science behind lens flares. The method is patent-pending, and will be presented later this year at SIGGRAPH 2011.

Here’s a mind-blowing demo reel by Stargate Studios that will make you doubt everything you see on television in the future.
“Modern Times” is a short film that offers a glimpse of the future in both the story that it tells and the way it was made — it’s a low/no budget film created entirely against a green screen with friends as actors. Maybe in the future shooting at real locations (or with real people) will be less and less necessary as CGI continues to become more and more mind-boggling.
Alex Roman, the genius behind the breathtaking “The Third & The Seventh“, recently created this short commercial spot for Grupo Cosentino. It’s certainly stunning, but here’s the kicker: it’s completely computer generated, created by two people over the course of two and a half months.
“Nuit Blanche” is a 4-minute long short film by Arev Manoukian of SpyFilms that will blow your mind. While you’re watching it, try to guess how it was created — see if you can pick out what’s real and what’s “shopped“. It may remind you a bit of The Third & The Seventh, another mind-blogging short we shared at the beginning of the year.
The latest Transformers movie to crawl out of the Hollywood cookie-cutter machine had a budget of $200 million. The above 2.5 minute short film was created by Amateur Russian filmmaker Alexander Semenov using a Canon 550D (with a 18-55mm kit lens and 50mm 1.8) and a Nikon D5000 (with a 18-55mm kit lens). In other words, the gear used was entry-level quality with kit lenses.
The footage was captured in two hours of shooting, and a month was spent editing the film. It’s amazing what a couple kids can create with a couple sub-$1000 DSLRs. We’re going to be seeing much more of this kind of thing as HD video recording because a necessary feature on new cameras.

If you were reading PetaPixel earlier this year, you probably remember the jaw-dropping CGI animation titled “The Third & The Seventh“. Here’s another extremely realistic and detailed computer-generated animation that simulates a camera traveling through a classroom (with lens flares and all). It was created by Israel-based Studio Aiko.
The scene was modeled using 3D Max and rendered with V-Ray, and was created over a period of 6 months.
HBO posted this interesting behind-the-scenes video that gives a glimpse into the kind of special effects that went into filming the popular miniseries John Adams. It’s pretty crazy how they construct entire realities around the actors using CGI.
And you thought Photoshopping was hard…
Freddy Wong’s YouTube channel is a must-subscribe if you’re interested in video editing and home-brewed CGI. A couple months ago we featured an amazing video they made where an entire action scene was done using light-painting techniques. What’s neat about their channel is that they also create behind-the-scenes clips explaining how each one was made.
