📜 New SIGGRAPH 2025 paper 🎉

❔How to compute bounding volumes for procedural Signed Distance Fields (SDFs)? This is not so trivial!

💡We propose a simple method called Sphere Carving. It extracts (convex) bounding volumes around SDFs, requires very few evaluations, and is GPU compatible.

Americans, Be Warned: Lessons From Reddit’s Chaotic UK Age Age verification has officially arrived in the UK thanks to the Online Safety Act (OSA), a UK law requiring online platforms to check that all UK-based users are at least eighteen years old before

The UK age verification rollout, chaotic as it is, is a proving ground for platforms that are looking ahead to using it on a global scale. In the US, there’s never been a better time to get educated and get loud about the dangers of this legislation. www.eff.org/deeplinks/2...

"Ethiopia’s Tigray war, which lasted from 2020 to 2022, is one of the most criminally under-covered conflicts in modern history"

“It is a really horrific and extreme form of sexual violence, and one that deserves the world’s attention.”🧵

Don't use a free VPN though, they sell your data and it's not safe. Do some research to see what the paid options are. Lots of benefits from having a good one 👌🏽
