How Vector Maps Work - Vladimir Agafonkin (Mapbox.com)

Показать описание

Mapbox GL is the leading open source platform for modern interactive maps. It combines a variety of sophisticated algorithms, smart ideas, and novel approaches to deliver elegant, real-time rendering of vector data with thousands of shapes and millions of points both in the browser and on mobile devices. In this talk, you will find out how it works under the hood, and learn about challenges developers face when building data visualizations with OpenGL/WebGL.
The talk will cover scalable font rendering, line and polygon tessellation, in-browser spatial indexing, collision detection, label placement, point clustering, shape clipping, line simplification, sprite packing, efficient binary data encoding and transfer, parallel processing using Web Workers, rendering tests and more!
