Hi all! A (re)-introduction: I'm Tyler, developer of #rayshader and the #rayverse, a collection of R packages for 3D #dataviz and #mapping.

Here's one of my greatest hits (now that Bluesky supports videos!): The Earth's submarine fiber optic cable network, visualized in #RStats with #rayrender.

Sur un #R du #30DayMapChallenge #line, j'ai découvert le pkg #rayshader (3D).

J'ai donc pensé à représenter mon île, la Réunion, selon l'altitude 😊 avec le 3 cirques et le Piton des Neiges qui culmine à 3070m. #rstats

#30DayMapChallenge – Day 5: Earth
Given the importance of these, global occurrence of rare earth elements according to U.S. Geological Survey (USGS) and the great hashtag#rayrender package in R.

I think that @davisvaughan.bsky.social figured this out.

add the following to your settings.json should do the trick
"window.title": "${activeEditorShort}${separator}${rootName}${separator}${profileName}${separator}${activeRepositoryBranchName}"

Day 6 of the #30DayMapChallenge (3D), a render of Mount Rainier with a realistic atmospheric skydome generated w/ a lat/long/datetime, rendered entirely in #RStats with #rayshader and #rayrender! The atmosphere is annoyingly realistic: I now have to dial in the exposure depending on the time of day!

3D Tanaka contour map of Scotland with #rayshader for Day 6 of the #30DayMapChallenge - Dimensions.

Thanks @milos-makes-maps.bsky.social for the helpful tutorial!

Day 6 of the #30DayMapChallenge makes things 3D! I took my elevation map from yesterday and made it so with the {rayshader} package.

Had a bit of fun making a new map of the False Creek area
Still a work in progress, but I like the direction

A little bit of #ggplot2 and #rayshader for the "dimensions" prompt on day 6 of the #30DayMapChallenge! 🌧️

I like Positron a lot for package development*! But after a year-ish of using it, I find myself consistently sticking with RStudio for data analysis work. RStudio just has a much higher SNR and it's fixed layout is much less prone to clutter, which is nice for cognitive-heavy loads.

Big cool features coming to the #rayverse: it only took a half year of CRAN ping pong for 3 low level infra packages with challenging configurations and a complete internal overhaul of rayimage to support proper colorspace management, all to just set the stage for the actual cool stuff :) #RStats

Molybdenite, huh? Time to post this animated 3D view of the Climax Mine with its big exotic-colored tailings ponds perched up on the Continental Divide. Created with #rayshader.

Stuff in space can be big so I want to have big detailed surfaces. I implemented old-school tilemaps (like from 2D consoles and 80s video arcades) in a pixel shader. 64K x 64K texels. Like virtual texture, but tiles all loaded, unmipped page table, shader manually bilinear-filters across tile edges.

I made a new kind of map
This one is of the City of North Vancouver, with City Hall right at the centre
Still a work in progress, both in understanding the code and in the design

Big thank you to @milos-makes-maps.bsky.social who made a great tutorial video and shared his code!
