There are two versions of the simulations, a rough draft version and a corresponding detailed, expensive one. (Image: Chu, Thuerey / TUM). In the embedded video from 2015 Nils Thuerey explains his research on simulating fluids.
Research news Compare any movie from the early nineties with one from 2017, and you'll see just how far moviemakers have progressed in their use of CGI - computer generated imagery - for realistically simulating either parts of or entire scenes in a movie. Nonetheless, natural-looking smoke and clouds remain among the most difficult effects to simulate. Researchers at the Technical University of Munich (TUM) have now developed a new CGI methodology that promises to be a game changer. Having worked previously as the R&D lead on movies such as "Iron Man 3" and "Super Man: Man of Steel" at the heart of Hollywood at ScanlineVFX in Los Angeles, Nils Thuerey knows first-hand how time consuming, tedious and expensive this process is. He already has one Technical Oscar Award under his belt for his groundbreaking work in the field of physics simulations for visual effects and CGI. At the TUM, the Professor for Games Engineering works in the field of simulating liquids and gasses, which fall into the general category of fluids. Rendering the vast amount of detail and the complex motions visible in real-life smoke clouds has been a long-standing challenge for fluid simulations in computer graphics.
