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 completeness: The N5000 dataset I'm using is under a CC-by license from @kartverket@twitter.com) https://kartkatalog.geonorge.no/metadata/n5000-raster/7e1b827e-3ccd-48a8-91ce-cc8125d6e4c1

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.

Take *this*, raster reprojection algorithms!

Just when I thought I had a good understanding of WebGL and thought it wasn't weird anymore, I discover a specific functionality in WebGL1 contexts that is not available on WebGL2 contexts. Damn.

Enviando una propuesta de última hora a @SIGLibreGirona@twitter.com con la frase «computación en el borde de álgebra ráster de GeoTIFFs multibanda a precisión completa»
Parecen buzzwords, pero TIENE SENTIDO.

A mí una cosa que me sorprende de la gente de derechas es que la gestión privada es más eficiente, pero sólo hasta que llega la UME.

The code is not 100% feature complete, documentation lacks a bit, but at least I can finally prototype WebGL pipelines and algorithms without going insane.

I must be one of the very few people who are happy to trigger a «TypeError: Failed to execute 'shaderSource' on 'WebGL2RenderingContext': parameter 1 is not of type 'WebGLShader'» error.

An unexpected side effect of following the newyearly rite of watching @cachitos_tve@twitter.com is uncovering archive content that can make the entire furry subculture cringe. I must ask @qdot@twitter.com to spread this. https://www.youtube.com/watch?v=-D-RZrM-fVQ
