In fact EPFL allows Thunderbird for Android. So only Outlook, Apple Mail, Google Mail and Thunderbird are supported on Android. See here: www.epfl.ch/campus/servi...

EPFL is fully migrating to Exchange Online without IMAP support? Outlook or Google Mail are the only supported mail clients on Android. Why are big universities not promoting open source and free alternatives anymore? Also, what's the amount of money EPFL pays to MS... @icepfl.bsky.social

@researchgate.bsky.social is practically unusable at EPFL's network because of "high traffic" (surprise at an academic institution) Ending up in a loop of "verify" and login.
I need to test a potentially broken DDR 5 RAM stick. Not sure if it's my mainboard or the RAM. Anyone EPFL (@icepfl.bsky.social, @epfl-ai-center.bsky.social , ...) can provide me access to theirs to test my RAM? None of the IT helpdesks (STI, BC, Poseidon) could reasonably help me.
Anyone else having huge troubles with @thorlabs.bsky.social orders recently? We ordered mid of November. Some shipments arrived (but parts are missing even though indicated on the deliver note). Also, some other items haven't arrived yet even though Thorlabs promised shipping beginning of December.
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)
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.
