Could Google Street View feel like a cinematic video? I made this clip with Wan 2.2 model by performing a latent space interpolation between two GSV images. It creates the entire fluid journey between them—no 3D geometry used. Realtime inference though 😅 #GenAI #videogeneration

Could also be used for Aerial to Street View in @googlemaps , a test here:

Real-time visual effects, running 100% locally in your browser! 🚀 I created a demo where you can just drop your video and watch it analyze feature points and optical flow for some cool visual effects! Have fun 😊 Demo: whenistheweekend.com/vfx.htm… #ComputerVision #VFX

Turn any video into a 3D hologram ✨ Excited to share a working prototype that explores this, making standard videos feel more organic in WebXR. By leveraging video depth data, we can bring them to life as interactive particle clouds. Demo: whenistheweekend.com/hologra… #XR

Another Example captured on the Quest. Note that it's all running in WebXR thanks to @threejs, Hand occlusion and co :)

The method I used to estimate the depthmap (consistent in time!) comes from this brilliant paper :github.com/DepthAnything/Vid… (CVPR2025)

Enhanced my Tennis Viz for Roland Garros! With live player distance tracking, a top-view heatmap, and speed-dependent motion blur. I should run it for a complete game. I wonder how many kilometers they run in a Game?! 🎾

Created an automatic motion blur effect for Tennis using Computer Vision 🎾 Any other visualization ideas for Roland Garros ? 🙂 Tech side: I used Tracknet + YOLOs

Created a CGI portrait with a vibrant gold necklace that flows subtly. Makes me wonder—could this necklace be crafted in reality? 🌟 #MadeWithBlender

Apply dynamic FX to your dance videos as they play 🙂 I built this fun web prototype using AI body tracking to add real-time effects like glowing trails and particles that react to movement. It all runs in your browser – try it here: whenistheweekend.com/dance.h…

Black Mirror vibes, working for real 😉 Quick & dirty prototype that turns photos into walkable 3D worlds. Exploring how to bring vintage photos to life in Mixed Reality using Monocular 3D Estimation Walk inside photos using a Quest 3 demo: 👉 whenistheweekend.com/futurep…

Ever fascinated by Depth Estimation and 3D reconstruction from a single image, I just tested the newly released PSHUMAN paper using the image on the left. Truly impressive results, Congrats on the amazing work! 🔥@YuanLiu41955461

My mini tornado prototype finally works! 😀
Readers added context they thought people might want to know
it's cgi, it was expressly declared by the creator shortly after. this is the video of the creator creating it. x.com/AlexandreDevau…
