Question for QGIS users. I'm using 'point cluster' symbology (in Firenze), and I want to scale the markers according to number of points in the cluster. Is it possible? I thought there was a variable cluster_size but not seeing it? šŸ˜• #gischat #qgis.

here's the node network. It's using adaptive subdivision, and a radial gradient (driven by frame count) as a multiplier to make the land rise. By changing colour ramp you can go for different looks

Woot! After several failed attempts, got a #rayverse render to work on my Windows laptop. šŸ˜ Used Bing Chat to give me a code snippet that actually worked. Not used R for a long time, so stoked to be playing with it again. (Also, is POVRay still a thing? šŸ¤”)

The source map stops just south of the Jordan Burn, so anything south of this is a guess. I'm more confident about the Canaan Lane location; there's a wall mounted marker opposite the entrance to Woodburn House.

LCD Pixel animation, in Blender. Used geometry nodes with "Geometry proximity" node to choose between lit/unlit pixels. Font is agressively scaled and with no antialiasing, got some 80s/90s look.

Tip: In edit mode, select a sea face, then select faces which are "similar by Normal" with a tolerance of 0 to choose flat areas for deletion or material assignment). Also good for keeping mesh count down.

More sobel rendering in Blender. These are the Cullins in Skye, using OS OpenTerrain 50. Used cryptomatte in compositor to render flat areas differently

DEMs for Svalbard and Norway's other polar outposts are here. , these are way outside the SRTM extents. Now, the hunt for Greenland DEMs begins. this looks promising:
