Still less than 24 hours late for Day 4: A bad map.

For this map I added a glitch to the way I'm tessellating geometry by randomly throwing out vertices.

In tonight's #gleo news: Edge detection on pseudo-voronoi cells, generated real-time from a point dataset.
Also: hovering the mouse over a cell triggers a JS event which can e.g. display a pop-up on top of the data point that generated that cell.
Can any of you folks guess the dataset?

I'm working on real-time #WebGL hexbinning. And it (mostly) works.

In further Gleo news today: TwinkleFields.
It's an animated scalar field visualization: the larger the value of the scalar field, the greater the probability of a pixel twinkling.
(Which pairs nicely with "intensified" circles/fills/etc, or "HeatPoint"s)

In today's Gleo news:
"intensify" symbol decorator. Take any solid-colour existing symbol (e.g. a circle fill), and replace its colour with the intensity added to a scalar field (like a heatmap).
Note that the HeatMap-specific "HeatPoint" has fading intensity, whereas the intensified circles have constant intensity.

I have written a thing about how I'm extruding linestrings in Gleo, with #WebGL and way more trigonometry than I'd like: https://ivan.sanchezortega.es/development/2023/02/06/reinventing-line-joins.html

Reinventing line joins

I’ve been working on Gleo for months now. When I started with it, I was pretty sure I had to reinvent big chunks of a vector rendering pipeline, come with te...

Hello Fosstodon! 👋

Time to give you a go and see if you're a viable alternative for data, visualisation and renewable energy related stuff.

I've attached a fun map of "live" wind turbine output that I've been working on recently as a little taster of what's to come ⚡️
