WebGL allows for fast graphics rendering on most web browsers, but also inherits undesired traits from from its videogame legacy. One of these traits is low numerical precision on integer and floating point operations.
Tiling datasets has allowed tiles (both raster and vector) to dominate web applications since tiles can easily overcome these problems. This talk will explore the opposite: possible ways to overcome numerical precision challenges in untiled datasets, as well as the dreaded antimeridian artefacts in coordinate systems which wrap around the globe.
An exploration on how a seemingly obscure web standard (WebRTC) can be exploited to provide P2P transmission of rendered map tiles.
A live coding session on Leaflet web maps, with some of its plugins. Just a showcase of common and not-so-common things that can be done on a web map.
A live coding session on WebGL graphics manipulation: abstract shaders, pixel manipulation on multisample rasters, and "classic" GIS map symbols.
A cozy chat about family, freedom and why we do free/libre/open source software.
