No physics libraries? No raycasts? That's right! The track... is a spline that lets us easily figure out the normals and tangents at any given point on the curve. This makes collision and twisting tracks simple and super performant. Reply if you want an in-depth break down 😃show more

At any point on a curve, there's one circle... that fits the curve better than any other. It touches the curve at that point, leans in the same direction, and bends by the same amount. It tells you how sharply the curve is bending at that exact spot, and which way it's leaning. If the curve is bending sharply, the circle is small. If the curve is nearly straight, the circle is huge. The osculating circle of the curve.show more

China just dropped an open source model that turns... any phone into a 3D scanner you point it at a room and walk through it the whole space builds itself into a 3D point cloud in real time as the camera moves, no LiDAR and no depth sensor anywhere it held a full 13 minute walkthrough at 25,000 frames without the map drifting or collapsing > ~20 fps on a single GPU > works indoors and outdoors from plain footage > the scan normally needs a $50,000 rig and a technician > Apache 2.0 and runs fully offline on your machine repo in the replyshow more

In 2022, Carlos Alcaraz hit an unreturned serve out... wide on match point to claim the US Open title and the world No.1 ranking. In 2025, Carlos Alcaraz hit an unreturned serve out wide on match point to reclaim the US Open title and the world No.1 ranking.show more

Steal this idea: An app that lets you chat... with the owners of any other vehicle out there. Someone is not giving you side and driving in an overtaking lane? You can simple enter his car number in the app and ping the driver small pre designed sentences like - hatt ja bhai.show more

I'll always root for a team that open-sources its... best work, and Robbyant just did it properly. Robbyant, Ant Group's embodied-AI company, released LingBot-Vision, a vision foundation model for robots, and the part I love is the data. They trained it on 161M images, filtered down from 2B raw ones and mostly pulled straight from the open web, with no human labels, no edge detectors, no depth sensors anywhere in the loop. It learns the exact edges of objects from raw pixels. That's roughly a tenth of the data DINOv3 saw, and under a third of the training. And it shows in the results. On depth, working out how far away things are, the 1B model edges out a 7B on NYU-Depth. It also powers LingBot-Depth 2.0, which reads the surfaces cameras usually choke on, glass and mirrors, and halves indoor depth error. LingBot-Vision is fully open. Weights from the 1.1B flagship down to a tiny 21M version, code, and the paper. This is the timeline I want more of. Robbyantshow more

The Fondant Custom Normals Blender addon is being tested,... and we're aiming for a 1.0 release next week! The first feature is the Weighted Normals + Laplacian Smoothing Geometry Nodes modifier. This let's you calculate Normals that are as clean as a nice quad mesh even if your topology is a mess and triangulated! We'll be following up with more tools to support creating high quality Normals for 3D anime and vtuber characters. We have an optimized adjustable Face Normal Transfer proxy mesh nearly ready to go. Check out the Docs to see more about the Addon's features and workflow (link in the reply.)show more

I'd say at the very beginning of retirement you... wanna be everything and you're willing to be, you love traveling around the world to meet friends and see what kind of lives people live in. and soon, you get frustrated and bored to live in an lifestyle that people thought a FIREd guy would be. you thought you're going up but you're not at the ground and it is no upside or downside at all. that's the problem. someday you'll figure out your problem is exactly the result that you got out of the Matrix. you're like trueman heading out of his little island, you've got no audience and it still a long way to go. there's no meaning but willingness for life we choosed, there's no up and down, no left or right. the fate we created, the failures we accept it, all that happened beyond our little island made our stories. and in case you don't see me, enjoy everything you're going to meet and have good days.show more

See that ponytail right under the tactical helmet? That... is Israel’s answer to an enemy that thought we would ever break. 🇮🇱💪Our lions and lionesses are on the front lines, shoulder to shoulder in the dust and danger, so our families can sleep at night. The government has their backs, the IDF is getting the job done, and the terrorists? They know the games are finally over. Just look at that engineering tool in the background clearing out the filth. No mercy. 🚜💥 If you believe in TOTAL VICTORY over terror, write an TOTAL VICTORY 🇮🇱 in the comments!show more

Super cool to see FSD track a hidden hazard... on the road! FSD spots a tire ahead. The van in front runs it over. FSD tracks it through full occlusion and is already moving over before it reappears I didn’t want to take any chances at the end, so I took overshow more

🚨 SEMI DRIVER STOPS 18-WHEELER LOADED WITH BRAND-NEW CARS... ON TRAIN TRACKS… WHAT HAPPENS NEXT IS INSANE In Schertz, Texas, an 18-wheeler packed with new cars got stuck on the tracks and within seconds, a speeding freight train came out of nowhere and obliterated everything in its path. The collision looked like an explosion. Cars launched into the air. Metal twisted like paper. The entire trailer erased in an instant. No one killed - somehow. What’s the very first question that comes to your mind watching this?show more
