Imagine 3D printing directly onto an object that already exists.

With Tomographic Volumetric Additive Manufacturing (TVAM), we can now print over existing components, opening up a world of possibilities for multi-component devices.

NeurIPS participation in Europe We seek to understand if there is interest in being able to attend NeurIPS in Europe, i.e. without travelling to San Diego, US. In the following, assume that it is possible to present accepted papers ...

Would you present your next NeurIPS paper in Europe instead of traveling to San Diego (US) if this was an option? Søren Hauberg (DTU) and I would love to hear the answer through this poll: (1/6)

Pertes militaires françaises en Afghanistan — Wikipédia

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?

Having worked for 3 years alongside Nicolas, I can confidently say that he is the whole package: he's super sharp, incredibly motivated and his unwavering enthusiasm has brought life to the lab every single day. Hire him !

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.

We are excited to present a SIGGRAPH Asia paper exploring a new application of inverse rendering to Tomographic Volumetric Additive Manufacturing (TVAM), a new light-based 3D printing technology that can print objects in less than a minute.

Following over 1.5 years of hard work (w/@njroussel.bsky.social &@rtabbara.bsky.social), we just released a brand-new version of Dr.Jit (v1.0), my lab's differentiable rendering compiler along with an updated Mitsuba (v3.6). The list of changes is insanely long—here is what we're most excited about🧵

My team RGL is looking for new PhD students starting 2025. If you are excited about topics like inverse rendering, compilers for graphics, and physically based modeling then please join us at EPFL. Info about the lab & admission process: rgl.epfl.ch/pages/jobs (Deadline: Dec 15)
