Progressive High-Quality Rendering for Interactive Information Cartography using WebGL

Limberger, Daniel; Pursche, Marcel; Klimke, Jan; Döllner, Jürgen in Proceedings of the 22nd International Conference on 3D Web Technology page 4 . ACM , 2017 .

Information cartography services provided via web-based clients using real-time rendering do not always necessitate a continuous stream of updates in the visual display. This paper shows how progressive rendering by means of multi-frame sampling and frame accumulation can introduce high-quality visual effects using robust and straightforward implementations. For it, (1) a suitable rendering loop is described, (2) WebGL limitations are discussed, and (3) an adaption of THREE.js featuring progressive anti-aliasing, screen-space ambient occlusion, and depth of field is detailed. Furthermore, sampling strategies are discussed and rendering performance is evaluated, emphasizing the low per-frame costs of this approach.
