Researcher Rafael Padilla explains how Hierarchical Progressive Rendering uses scene changes and light transport to prioritize the pixels that matter most for path tracing. "Path tracing can produce incredibly high-quality images, but when you make a small change to a scene, the renderer often has to effectively start over.... show more

EnvGS: Modeling View-Dependent Appearance with Environment Gaussian Contributions: • We propose a novel scene representation for accurately modeling complex near-field and high-frequency reflections in real-world environments. • We developed a real-time ray-tracing renderer for 2DGS, enabling joint optimization of our representation for accurate scene reconstruction while achieving real-time rendering speeds. • Extensive experiments show that EnvGS significantly outperforms previous methods. To the best of our knowledge, EnvGS is the first method to achieve real-time photorealistic specular reflections synthesis in real-world scenes.

World Labs CEO Dr. Fei-Fei Li explains says "world model" has become an overloaded term & explains what each kind of world model does: "Right now there are three ways of calling world models when it comes to spatial intelligence." "One is what I call a renderer, when the model puts beautiful pixels on the screen." "Another kind of world model is what we call a planner. That is more for machines, more for robots." "The third kind, which I think is the linchpin of the three, is a simulator." "A simulator could become a renderer. The simulator could become a planner. But this layer is a huge critical path to unlock spatial intelligence. And that's what World Labs is working on." Fei-Fei Li at Bloomberg Tech live with Emily Chang

With Atlas, you can literally make films. And it also basically solves first-frame-last-frame transitions. Reconstruct a 3D scene from images, then position the camera exactly where you want it, and let Atlas fill in what the camera would see along that path. You’re in the director's chair, staging the scene. Here we made a 1 min video with a couple images of totally different scenes, and we set where the camera keyframes should move through each part of the scene. The scene-to-scene transitions are great. Atlas makes it feel like a smooth shot with no cuts.

The reason why Reflections in GTA 6 look noisy and blurry isn't because Rockstar Games doesn't know how to do them or that a $2 billion budget magically fixes this. It all comes down to the GPU in current gen consoles, these consoles don't have the power they need to render high resolution Ray Traced reflections in real-time and corners had to be cut. Here I'm running GTA 5 enhanced for PC at ultra settings to show you how good and clean the reflections look if you have high-end and recent hardware that have AI upscaling to make this possible. That being said, The PS5 Pro console is much more powerful compared to the base PS5 (the footage which GTA 6 was captured) offering higher resolution, 45% faster rendering, 2X-3X better Ray Tracing performance and PSSR upscaling. With the PS5 Pro, it will have significantly better looking and sharper reflections somewhat close to what GTA 5 Enhanced reflections look like on a gaming PC at high settings. However, the ultimate experience will still be on PC when GTA 6 launches, allowing for the highest quality Ray Tracing or even Path Tracing if Rockstar Games decides to implement it.

Almost 5 years after DXR's release Cyberpunk 2077 is the first AAA game with a near fully path traced rendering mode, but how did we get here so quickly? In this vid I go over the confluence of technologies that make it happen and where tech might go next!

OUR PATH ONLY APPEARS AFTER WE TAKE THE FIRST STEP We often tell ourselves that we'll begin once we know exactly where we're going-once we have a plan, a guarantee, or proof that everything will work out. But life rarely gives us the entire path in advance. Sometimes clarity is not what allows us to move. Sometimes movement is what creates clarity. The first step may feel terrifying because there is nothing visible beneath it. But courage is not walking forward because you can see the way. Courage is moving forward while trusting that the way will meet you. You may not need to know how the whole journey unfolds. You may only need enough faith for the step directly in front of you. And perhaps the path you've been waiting to see has been waiting for you to begin. As we start to walk on the path, the path appears. Take the step.

How much of your life is being shaped by decisions you don’t realise you’re making? Seth Godin has spent decades trying to understand that question. Seth is one of the most influential thinkers in modern marketing, leadership and creativity. He’s a bestselling author who has written more than 20 books, and when I started my career in marketing, his ideas were everywhere. So sitting down with him felt like a full-circle moment. I wanted to find out why we stay in careers, businesses and relationships we know aren’t working, how to know when quitting is the right decision, and what happens as AI changes the world of work. We discussed things like: - How to know when it’s time to quit. - Why fear, status and belonging shape your choices. - Why AI could change the world more than we expect. - The human skills that could matter more in an AI world. - How to take back control when you feel stuck. One of Seth’s main talking points is that there are forces shaping our decisions that most of us rarely stop to notice. Fear, status, the years or money we’ve already invested, and the systems around us can all make us feel like we have fewer choices than we actually do. What I like about Seth is that he doesn’t tell you what decision to make. He helps you see what is influencing that decision so you can make it for yourself. With AI changing so quickly, I think the ability to adapt, question the path you’re on and know when to change direction is going to matter more than ever. Seth said something that I think sits at the heart of this entire conversation: “We still get to decide.” When so much around us is changing, remembering that we still have a say in what happens next really matters. Out now on all platforms. Let me know what you think of this one in the comments ❤️

I created a 3D Gaussian Splat of my kitchen using 1/3rd the images it used to take me by using NVIDIA AI Developer's 3DGRUT! I can now use 180 degree fisheye images and ray tracing to make detailed splats. The only reason the scene isn't sharper is because my input images weren't super sharp - when I took the images back in October, I was still learning to use the lens. I plan to make a "first reactions/overview video". Tutorial after that. For reference, this took 206 images and the ultrawide on my iPhone took 608 images to capture. #3D #AEC #Computervision

Mark Zuckerberg reveals why Elon Musk was right to fire 80% of Twitter's employees: "Elon led a push early on to make Twitter a lot leaner. You can agree or disagree with exactly all the tactics, but a lot of the specific principles that he pushed on around basically trying to make the organization more technical, around decreasing the distance between engineers of the company and him, fewer layers of management, I think those were generally good changes" "I also think that it was probably good for the industry that he made those changes because my sense is that there were a lot of other people who thought those were good changes but who may have been a little shy about doing them" "Just in my conversations with other founders and how people have reacted to the things that we've done, what I've heard from a lot of folks is when someone like you, when I wrote the letter outlining the organizational changes I wanted to make back in March and when people see what Elon is doing, that gives people the ability to think through how to shape their organizations in a way that can be good for the industry and make all these companies more productive over time" "That was one where I think he was quite ahead of a bunch of the other companies on. Certainly his actions led me and I think a lot of other folks in the industry to think about, hey, are we kind of doing this as much as we should? Could we make our companies better by pushing on some of these same principles?"

Quick video on how I used claude code, icon composer, and my iOS app to make my app icon. I got a ton of questions about how I did it: It started with two questions: can you reshape the route to approximate a "p" more but like a character of a p not a real "p" as a test icon? "Can you give me a settings sheet where I can parametrically create The loop that I want to make... like, give me every possible parameter for the loop in the three d scene, and then make sure I can copy those values to you. And we could take that and implement it. I think that might be faster for me to be able to manipulate a p shaped loop."

007 First Light had a budget of over $200 million and took 7 years to make. That makes it the most expensive entertainment product in Denmark's history. I can definitely see where all that budget went, it shows. The quality level is insane.

Bladee has been making music for over a decade, but his fanbase hasn’t aged. In a recent interview with Resident Advisor, the Drain Gang artist spoke about that disconnect. He links part of this to lineage, tracing a line from the SoundCloud rap scene he came up in to the newer underground one that’s replaced it, a scene he says he still exists in. That continuity raises its own question for him, whether he’s stuck “making teenager music forever.” Bladee arrives at something closer to peace with it, saying that he thinks it’s good to “connect with the kids, the youth... the future.”

“You cannot make a choice and then sit back and wait for what God will put in your hands. While you are waiting for God to place things in your hands, he has already given you those hands to use, he gave you arms to work and sustain yourself, and be able to live as the dignified human being he created you to be. That is what is supposed to guide us, that is what should determine the path we follow. We were able to overcome our bad history, but what was the goal? It was for people to live well, and make progress; for the country to develop, and to build a country where Rwandans are proud of who they are and where they are going. And where they are the ones to decide what to do with their lives. Everything else, the support we receive, the partnerships, can only build on that.” President Kagame | Interview with RBA.

The NYT interview with Taylor Swift on her songwriting process is so good. Here she explains her approach to choruses and bridges: “The importance for me of a bridge is it just feels like we’re painting a picture. We’re setting a scene. We have this opportunity as a songwriter to tell an entire story. Or an entire movie. Or a very detailed description of one scene in a movie. Or a very nuanced dynamic between people or a complicated emotion. And we have only so long to do this. I’ve written some really long songs in my life. But, for the most part, they’re between 3.5 to 4 minutes. You can start painting the picture in the verse. You can get to the heart of it at the chorus. But then the bridge can be where you zoom back, you walk 20 feet back, and you see what this entire painting was supposed to be. You’ve seen brushstrokes. You’ve seen the color tones. But the bridge can be when you step back and you feel everything that that piece of art was supposed to make you feel. That’s just how I feel about bridges. I came up as a songwriter in Nashville, where structure is a huge part of how you effectively tell a story, right? You go verse - chorus - second verse - chorus - bridge - chorus. Maybe you repeat that first verse if you want to. If you want to pull at some heartstrings. If it makes sense. Now, that’s something that I absolutely subscribe to…that structure is important. But I think that when you write enough songs — at least in my case — the intuitive part of your songwriting brain can kind of create a new structure that’s not as classically what you’ve been taught. Jack Antonoff is a collaborator of mine and one of my best friends. We established this thing that we love to do and we call it the rant bridge. I could point to examples like, ‘Out of the Woods’, ‘Is It Over Now?’ or ‘Cruel Summer’. And oftentimes we love these rant bridges, where it’s basically like stream of consciousness. Endless pouring-out of emotion. Intrusive thoughts, blended with metaphor with discussion with shouting. You want this rant bridge to feel the most intense of what that feeling is…that you’re trying to, establish over the course of the song and you want it to kind of be a crescendo.” *** Full interview here:

Nick Saban says one of the biggest mistakes leaders make when their environment changes is sitting around complaining about the new rules, and says his philosophy was that complaining is actually a distraction to the solution, so you should always spend that energy figuring out how to adapt “You have to be flexible, number one. If you’re flexible, then you have a willingness to adapt. And I think your willingness to adapt is really, really important because things are changing.” “There’s a lot of changes that are ongoing that you have to adapt to. And I think that rather than complain about it, which a lot of people sit around and complain…” “Complaining is actually a distraction to the solution. I think that you’ve got to spend most of your time trying to figure out, ‘What is the solution? How can we adapt?’” “That’s the way we’ve tried to look at all these challenges, to try to improve the quality of the program that we have.”

xenoblade chronicles 2 is fire and has absolutely zero flaws that being said, I think a redub or some changes to lipsyncing for the dub would be pretty cool this scene for example, is good, but better lip syncing could make it better imo

Today, I joined Congresswoman Goodlander Maggie Goodlander in a Concord, NH backyard with neighbors. We discussed how families in the area feel financially squeezed and struggle to pay their rent, mortgage, and other bills. Families are taking money out of their 401Ks just to make it to the end of the month. That’s so wrong on so many levels. Meanwhile, the children of wealthy parents are attending weekend seminars to learn how to manage their inheritance. Think about that for a second. To fix our broken politics, we need to give more Americans a path to a middle class life: a path to homeownership, a path to affordable healthcare, a path to quality education for their children, and a path to a secure retirement.
