We've rewritten the library from the ground up with the goal of offering a powerful, high-performance library leveraging the latest in web technologies such as Canvas and WebGL. This talk will present the latest advances of the library, focusing on aspects that make OpenLayers 3 stand out. OpenLayers 3, for example, uses techniques and algorithms that enable high-quality and high-performance vector rendering. Come learn about the optimizations and techniques OpenLayers 3 uses internally, and what makes OpenLayers 3 unique among its competitors.
