This week part of my team and I were at Cryassac tracksite, France. It was _phenomenal_ - some of the best tracks I've ever seen! You should definitely go if you get the chance.

It's big, it's tridactyl, and it's Hell Creek, so we reckon this is an adult Tyrannosaurus rex trackway. Paper here: www.tandfonline.com/doi/full/10....

Watched the cartoon Spider-man from 1994 with my three year old. He loved it, but the end spider-verse took some explaining, and the finale where 'our' spider-man goes to a universe where spider-man is a fictional character, and has a heart-to-heart with Stan Lee took some explaining...

I've still not found a soild, data-driven use case for gaussian splats, but there's no denying the fidelity of the visualization/reconstruction is vastly superior to photogrammetry. Left: RealityScan, Right: Lichtfeld Studio, both using same video input, with camera alignment done in RealityScan

Getting Dragonfly setup on Linux (runs better than Windows!) on my new laptop with a 5090, and wanted to push it, so here's a vole scanned at 13 microns resolution (70GB dataset)

When you have a deep, penetrative track, it turns out that sediment properties don't really affect the sub-surface morphology very much (for a given foot motion). This is good news for reconstructing #dinosaur foot motions from penetrative tracks: royalsocietypublishing.org/rsif/article...

Trying to resolve something with currys, I became exasperated at the stonewalling and delaying of their web chat, so I turned to Twitter. This is going swell...

I'm quite happy with this paper - I think it's a relatively accessible read, and includes our most advanced track simulations yet. Thanks to everyone at Palaeontology for making such a nice paper. onlinelibrary.wiley.com/doi/10.1111/...

The new focus stack + pixel shift on the new Nikon Z8 firmware is awesome! Those numbers are mm. 25 focus positions, with 32 pixel shift images at each position, totaling 64GB of RAW images before merge and stack. Nikkor MC 105mm.

In case anyone finds this useful, I've now added a 'shape fitter' to the #blender extensions library, allowing you to fit spheres, planes, and cylinders to vertex selections: extensions.blender.org/add-ons/shap...

I really like @zen-browser.app but any site that requires username password like this just always fails, and I have to return to a chromium browser. I think this is a firefox issue, but does anyone know a solution?

This would be the same expensive "custom" grants portal that includes the classic toggle: "Click "no" to add staff" When I asked years ago if our "custom" portal could have the wording changed: "no, that's beyond the scope of what we can do"

Ultimately, this frivolity was so I now have a complete workflow in one software, so can combine #xromm data with simulation data all in the same world space and time in Blender. Data here from 2014: www.pnas.org/doi/full/10.... Never before viewed in this integrated, complete, way

In a fit of coding insanity, I decided to port my Maya tools for generating LIGGGHTS input files to @blender.org as an addon (github.com/pfalkingham/...) AND I made a LIGGGHTS/LAMMPS importer for Blender to visualize outputs (github.com/pfalkingham/...) Very janky and buggy, but working:

Figures must be this dimension, and this PPI. But they must also be below 30MB. Me after an hour of fighting with various means of compression and downsampling while maintaining resolution and size:

I like #linux, I'd like to use it more but for a couple of workflow blockers But this is Linux and Linux users in a nutshell: 'working fine' *lists fairly major things not working* *Potential fix is recompiling the kernel* it's just not practical for normal people, or even techies that lack time.

At the risk of jumping on the #deepseek bandwagon, I'm finding it's tone to be just right. Here's the end of a conversation of me asking about email policies. I've not prompted to use this kind of language at all. I love it:
