The web is a complicated world where users are demanding and where small optimizations can make a big difference. Users want the information fast, but they also want the best quality. In terms of images, there is a well documented solution to that; Virtual Texturing. But when it comes to browsers and web application very few documentation exist and they lack technical details. This leads to my project which consists in the implementation of a Virtual Texturing engine for a web application. And this paper documents the details of my journey.
