I've just upgraded from "I write JS unit tests so I know which browser is weird" to "I write WebGL unit tests so I know which OpenGL rendering stack is weird".

I just submitted a talk proposal to @openstreetmap@twitter.com's SotM2021, about something completely experimental, that I'm no expert about, and that may even not be feasible. (BTW @gregorymarler@twitter.com, there shall be no singing this year) blog.openstreetmap.org/2021/03

Venga, que esta vez sí que estoy despierto para soltar una chapa de ráster y webgl en @SIGLibreGirona@twitter.com

Estoy gilipollas. Resulta que creo que envié dos veces la misma ponencia a @SIGLibreGirona@twitter.com, con dos títulos distintos, y yo tenía en mente nada más la de mañana.

: mañana soltaré una chapa sobre WebGL y Javascript (y compiladores, y cohesión-acoplamiento, y todas esas cositas chulas de ingeniería informática) meetup.com/es-ES/sevillajs/eve

Ojo a @SaveTheLab@twitter.com que está que lo peta. Yo sólo he escuchado críticas a la mudanza/desalojo, y ni una voz (pública) a favor. Yo digo que por algo será.

BEHOLD!
Raster reprojection for Leaflet, now available with Leaflet.ImageOverlay.Arrugator .
(It should be obvious that this uses my Arrugator mesh reprojection subdivision library, released yesterday)
gitlab.com/IvanSanchez/Leaflet
Repo contains link to the demo.

I'm thinking on adding some utility function or option to pre-split the mesh without the reprojected midpoints logic for this kind of CRSs.
Also, I need to take a photograph of @delawen@twitter.com's cat before publishing the draft short technical essay about the thing.

Kinda wishing there would be a special kind of hell for people to take photographs of their computer screens instead of using screenshot tools.

Tengo que dejar de leer los tuices de @marcosgcm@twitter.com y @jdelacueva@twitter.com sobre @SaveTheLab@twitter.com porque, de verdad, me va a hervir la sangre con tanto despropósito del ayuntamiento.

Coming soon™ to a @LeafletJS@twitter.com near you: WebGL-powered raster reprojection.

For extra trippy non-regular-grid conversion, look at EPSG:25833→EPSG:4326 (UTM30N→Equirectangular)

You might be thinking "This crazy Iván sure is using some kind of regular grid for this". Well, no. Be amazed at this EPSG:25833→EPSG:3031 reprojection (UTM30N→Antarctic Polar Stereographic)

I'm having a bit too much fun with my raster reprojection triangle subdivision thing now that UV-mapping is integrated. Here's @kartverket@twitter.com's N5000 raster, from EPSG:25833 (UTM30N) to EPSG:3857 (mercator spherical).

@RealIvanSanchez@twitter.com Deep down inside, I'm scared shitless that @mourner@twitter.com will come and redo this graph-edge manipulation algorithm thingie to make it like 8650% faster.
