12 out of the 90 French casualties were Foreign Legion, of which 8 were foreign-born, so that's quite a bit lower. (source: fr.wikipedia.org/wiki/Pertes_...)
This only counts deaths though, would be interesting to have a figure counting lasting physical and psychological injuries.

It's swapping the leg at some point, no?

It's essentially reverse CT scanning: powerful light patterns are projected from all angles around a vial containing photo-sensitive resin. Only regions that receive enough energy will polymerize, so you can print a given object by controlling which regions receive enough with well-crafted patterns.

This was a joint effort between EPFL's RGL and LAPD labs (@felixwechsler.bsky.social).
We release an open-source software, Dr.TVAM, which can be easily installed via pip. Please see the [documentation](drtvam.readthedocs.io) and our [paper](rgl.epfl.ch/publications...) for more details.

We also present an improved discretization scheme that keeps information about the printed object’s surface while optimizing, which alleviates pixelated artifacts coming from naively discretizing the target object on a regular voxel grid.

We demonstrate the versatility of our framework in novel printing configurations such as printing in a square container, which has a higher optical quality than glass-blown cylindrical vials.

In contrast, our framework is based on a differentiable renderer, therefore we can apply volume rendering techniques to accurately model scattering by participating media. We can produce higher-quality prints than previous methods in scattering media.

One key challenge in TVAM is computing projection patterns to print a particular object. Existing methods rely on a simplified light transport model to simulate absorption of energy inside the medium. When the resin contains scattering particles, this requires using approximations.
