[QGIS-Developer] Use of WebGL en Javascript (in Qt6 ?)

[Richard Duivenvoorde]

Hi Devs,

Anybody an idea about any possibilities to use WebGL and/or java/typescript in Qt6 (QGIS 4)?

Context: in the archive/museum world old maps are often made available via de IIIF (triple-I-F) standard.
Which nowadays has a georef standard: https://iiif.io/api/extension/georef/

A dutch guy, created https://allmaps.org/
A site in which you can 'easily' georeference those old images AND which keeps hold of the GCP's created.

So having a georeference IIF service/image it is easy to load it, georeferenced via the allmaps url (which is actually a json, referencing the IIIF service AND the GCP info:

https://viewer.allmaps.org/?url=https%3A%2F%2Fannotations.allmaps.org%2Fmanifests%2Fc390af06ea724803

All this is typescript/nodejs/javascript.

Rendering/transformation is done life on a WebGL 'canvas'.

In my ideal world, it would be possible to load the same url as above in QGIS, maybe do the realtime transformation in an 'offsite/buffered' WebGL canvas?

But maybe I'm too eager :-)
