This in-depth article by Georgios Karnas takes a look at the issue of coordinate precision faced by Uber for Deck.gl, their 3D spatial visualisation library. Specifically, Georgios digs into the limitations of floating-point precision in WebGL shaders and details how they worked around those limitations to accurately transform coordinates on the fly without sacrificing performance.
How (sometimes) assuming the Earth is “flat” helps speed up rendering in deck.gl
The latest v6.2 release of deck.gl includes a new feature that improves the rendering performance of geospatial visualization by up to 48x.
