some of the better renders I've done, I think
fixed up some color issues and we are looking a lot better, now this is an extremely cool application of the bidirectional tracing here you can see a beam being refracted through a series of spheres, and coming out the other side as a split distribution of colors

Wall textures, Hampi, India 2025

Pentax 645n, 45-85 4.5, Tmax 100 and Kodak Gold

#BelieveInFilm #India
Large cut stones in a huge well-constructed wall with small chinking stones in the crack. Similar segment of wall from slightly further away and in black and white. A similar wall construction but this one has a pretty relief carving on it. Another closeup of a joint in black and white.

Designing monochrome data visualisations | Nicola Rennie
In data visualisations, colours are often used to show values or categories of data. However, sometimes you might not be able to or want to use colour. This blog post discusses some tips for designing...

it's interesting, some of the multiple-refraction interactions start looking like iridescence

volumetric shadow mapping from a single camera render.
computing the volume shadows is O(log(voxelResolution.z)) complexity
a volumetric shadowmap of a few dining tables. the scene is rendered in white. the shadows are pure black

Gaussian splats are quite the rage lately (for good reason).

Yet the technique is actually quite old!


35 years ago, Lee Westover created the worlds first splat with the “UNC Head” dataset.

A high-res CT scan...much too detailed for computers at the time.

> We archived around 86M music files, representing around 99.6% of listens. It’s a little under 300TB. This is the largest music metadata database that is publicly available.

Many interesting 📊 charts on this page that can only be made by having this scale of data.

annas-archive.li/blog/backing...
Chart showing that 70% of songs are ones almost no one ever listens to (stream count < 1000). A chart titled "Stream Count Analysis by Popularity" showing a histogram of total streams peaking at popularity scores of 60–70, overlaid with a line graph showing average streams per song spiking exponentially at scores of 90–100. Below, a table lists the top three songs by stream count: "Die With A Smile," "BIRDS OF A FEATHER," and "DtMF." A matrix grid with the title "Audio Features Correlation Heatmaps" showing histograms of musical traits (Tempo, Energy, Valence, etc.) along the diagonal and 2D density heatmaps showing correlations between paired features in the intersecting cells.

amazing how much a -1 can mess up your whole thing - refraction is now using the real geometry instead of some weird mirror world

fixed up some color management issues and now getting much, much better results
some pretty gnarly output from the bidirectional spectral pathtracer

Ford Falcon Concorde.

This is what was taken from us.
A photo of a silver Ford Falcon panelvan covered in bodykit parts and black stripes up over the back. It's seriously just slathered in fibreglass from the bonnet scoop, front bar, wheel arches, nostrils, rear spoiler, all over it just everywhere. It looks part 70s muscle car, part cheap sf movie prop.

Cladonia lichen. Northwest Territories, Canada. #lichen #fungi #fungifriends
A green, cream and brown coloured Cladonia lichen. The top of the lichen consists of a platform-like structure with worm-like structures growing upward from it.

Here's some more Cool Tech. The Samsung GX TV from 1996, marketed to gamers, which had speakers that were also shutters. It's totally a gimmick and it sounds like CRT enthusiasts are not a big fan, but it certainly looked cool as hell.

The Samsung GX TV in its closed state, GX logo visible in the front The Samsung GX TV in its closed state with a better view of its circular stand and strangely shelled body The Samsung GX TV opened, speakers to its side, running Outrun Magazine advertisement for the Samsung GX TV, opened up and showing off its features, emphasizing the speakers to the side of the TV

Incidentally - I think this indicates that you can get diffraction in ray optics, using extremely complex geometry and a lot of bounces. This feels somewhat substantial.

interesting - this spectral renderer is a hop, skip, and a jump from simulated crystallography (someone I know recently did some work related to simulated crystal growth jbaker.graphics/writings/cry...) - this is a physical, real process used to identify crystals via their diffraction patterns
