I only mentioned HDR because the additional ~4 stops of dynamic range on HDR displays could make such a plot more interesting, especially if you split the "standard exposure" times by day/night. I've been working on a day/night atmospheric simulation package and using EXR output has been helpful.

The most amateur part is the consistency issues noted in the blog post: you can see clearly that some higher up decided everything needed to be an icon but didn't put bother first developing a topdown strategy to implement it, so it was all cobbled together at the working level.

This blog post on the proliferation of icons in macOS Tahoe makes the decision clear: I'm never updating to this cluttered mess. Where did your aesthetic taste go, Apple? Yuck. 🤮

quiz: as a developer, you own the full stack to:
a) avoid supply chain attacks
b) ensure a minimum level of code quality
c) do whatever you want because YOU DON'T OWN ME!
anyway, it's critical that any atmospheric rendering library have a full font rendering pipeline for, uh, reasons

Do you know it's been almost seven years since I released #rayrender, ranked for 6 years straight as the #1* pathtracer in #RStats? I went back to a blog post (www.tylermw.com/posts/rayver...) I wrote over six years and recreated some of the scenes, and it's fun seeing how far it's come!

Set `shadow = FALSE` in plot_3d(), which will remove the ground. Then set `transparent_background = TRUE` in `render_highquality()`, which will ensure any rays that intersect with the background are marked as transparent. This also will give you softer, anti-aliased edges versus a hard mask.

One thing I appreciate about {targets} is the robustness of the pipeline: if I need to stop a long, compute-intensive process to run something else (or, in this case, I resize a pane and make the IDE crash🤷♂️), I don't need to worry about corrupted state: just restart R and tar_make() away!

You can see the difference in the JFA by looking at the areas where the bonds and atoms intercept here in a molecule rendered with #raymolecule. The old method worked by placing an inverted mesh over the mesh, which results in issues where other meshes intersect (note the black lines on the bonds)

You can generate these materials via the rayvertex package (available in #rayshader with `render_snapshot(software_render = TRUE)`: practically, these can be mixed and matched with other materials when you want to emphasize (via visual separation) some element of the scene. #Dataviz

‼️ #rayverse package update: #rayvertex v0.14.0 released! This overhauls the toon shading algorithm to use a screen space jump fill algorithm (JFA), removing the brittle inverse mesh hack that existed up until now.

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
