Mercato – Le Real Madrid prolonge le sursis de Xabi Alonso



This episode of the Physics World Weekly podcast features Pat Hanrahan, who studied nuclear engineering and biophysics before becoming a founding employee of Pixar Animation Studios. As well as winning three Academy Awards for his work on computer animation, Hanrahan won the Association for Computing Machinery’s A.M. Turing Award for his contributions to 3D computer graphics, or CGI.
Earlier this year, Hanrahan spoke to Physics World’s Margaret Harris at the Heidelberg Laureate Forum in Germany. He explains how he was introduced to computer graphics by his need to visualize the results of computer simulations of nervous systems. That initial interest led him to Pixar and his development of physically-based rendering, which uses the principles of physics to create realistic images.
Hanrahan explains that light interacts with different materials in very different ways, making detailed animations very challenging. Indeed, he says that creating realistic looking skin is particularly difficult – comparing it to the quest for a grand unified theory in physics.
He also talks about how having a background in physics has helped his career – citing his physicist’s knack for creating good models and then using them to solve problems.
The post Oscar-winning computer scientist on the physics of computer animation appeared first on Physics World.

En France, il existe plusieurs véhicules de gendarmerie repérables grâce à leur couleur bleue. Cependant, toutes les voitures de l’institution n’ont pas la même teinte de bleu. Pourquoi le "bleu gendarmerie" n’est-il donc pas uniformisé ?
