I am thrilled to announce that Social Street View has won the Best Paper Award at Web3D 2016, which was held next to SIGGRAPH 2016 in late August! Please visit the project website for more details: http://www.socialstreetview.com I also published my slides and videos.

Tutorial and Resources for Three.js
Three.js is one of a number of free WebGL libraries. First released in April 2010, it has become pretty popular, and includes a huge number of demos. I wanted to know more about its origins, so interviewed its creator, Ricardo Cabello, aka mr.doob, who lives in Spain. Interestingly, I am also largely motivated by Demoscenes when I was…
