Tyler Morgan-WallHappy Groundhog Day! In honor of the day, here's an infinitely repeating video of a realistic atmospheric simulation showing the shadows the sun casts on February 2nd. (over Monterey Bay, California, because no one would want to go to Punxsutawney, PA right now).
3/5 We can use this information along with solar positioning via {swephR} to generate a beautifully rendered realistic atmosphere in our #rayrender and #rayshader plots! Rayshader's `render_highquality()` now optionally takes lat/long + datetime inputs, so you don't even need to learn anything new!
An "atmospheric" frame from an animation demonstrating the "Mahattanhenge" phenomenon in my upcoming blog post about rendering realistic atmospheres in R.
What's fun about rendering a long animation overnight is it makes each morning a miniature Christmas: you never know what you're going to unwrap! Sometimes it's wonderful, and sometimes you forget to increment the counter so you end up rendering the same frame over and over again 😉
terenceFound the code to do this strange attractor while looking for something else. Thought I'd see how fast I can render 360 frames of this with denoising.
What used to take hours now takes slightly more than 60 minutes.

apropos of nothing: using R to render a mastodon to post on mastodon
(this post made more sense on bluesky)
R: the language that sets the gold standard for dataviz!

(from a cheeky #rayshader figure in an upcoming blog post about rendering 3D plots with "golden hour" lighting by generating synthetic sunsets, entirely in #RStats with #rayrender)

#rayrender adventures, an #rstats tale
Do you know it's been almost 7 years since I released #rayrender, ranked for 6 years straight as the #1* pathtracer in #RStats? I went back to a blog post (https://www.tylermw.com/posts/rayverse/getting-started-with-rayrender.html) I wrote over six years and recreated some of the scenes, and it's fun seeing how far it's come! The original images took a long time to render and suffered from severe noise, but years of sampling improvements, BVH traversal efficiencies, and denoising support has made decent renders almost instantaneous!

Manhattanhenge: On May 28th/July 13th, the sun aligns with Manhattan's street grid 29° from N. This twice-a-year alignment of urban planning and orbital motion serves both as a temporal tourist attraction as well as a particular good test case for geospatial skymap alignment! #RStats #rayrender
