To my trans folks. I'm so sorry these assholes have decided to single you out for just trying to live your lives. It's a disgusting attack on a person's simple right to exist. I hope one day we bring them all to account - no tolerance for intolerance. Trans rights are human rights. Love you all.

Hotel Infinity Review: A Standout Example Of True Room-Scale VR

Hotel Infinity is a standout example of true room-scale VR, and a must-own for anyone interested in understanding the potential of this medium.

It feels like video games have become actively LESS like Third Spaces in the past 20 years, and more like eternal fucking shopping malls, JUST as physical space has. This is monstrous, and it's such a waste.

A thread of thoughts on radiance fields, from my keynote at 3DV: Radiance fields have had 3 distinct generations. First was NeRF: just posenc and a tiny MLP. This was slow to train but worked really well, and it was unusually compressed --- The NeRF was smaller than the images.

We often use discretization to approximate continuous laws of physics, but it also goes the other way: You can use continuous equations to approximate the behavior of discrete systems! Here we'll see how electrical circuits can be modeled using the Laplace equation Δφ=0. [1/n]

We just dropped CAT4D, text to dynamic 3D models that you can render in real time. Not posting a video because Bluesky is garbage in this respect; go straight to the real time viewer on a desktop browser and look around. The cat kneading dough is my favorite. cat-4d.github.io

CAT4D: Create Anything in 4D with Multi-View Video Diffusion Models

We present CAT4D, a method for creating 4D (dynamic 3D) scenes from monocular video. CAT4D leverages a multi-view video diffusion model trained on a diverse combination of datasets to enable novel vie...
