Working on Sparse Volumetric Light-maps. Thanks to CynicatPro🎃 for pointing me at Unreal's version. In a nutshell it's just another sparse voxel data structure. My implementation is, no doubt, different from Epic Games Store's own. I'm using 4x4x4 probe grid with intermediate nodes having very wide branching factor of...

So how is the Sega Dreamcast's very own native port of Mario Kart 64 coming along? Well, lets take a look at some footage I just captured directly from my DC of jnmartin's latest build! Minor texture corruption is still present on some of the sprites here and there, plus there's no audio yet, BUT MY OH MY! She's running like a dream and looks SHARP as hell at with progressive scan at twice the resolution! You'll immediately notice virtually all of the texture corruption on the text and UI sprites have been fixed. You can now actually see your item box, and clouds are drawn properly in the background, rather than over the top of the scene in the foreground. Somehow, along with fixing all of this in the past few days, jnmartin has also found the time to get the monitors in the backgrounds of Luigi's Raceway and Wario Stadium correctly projecting a view of the scene onto their screens. This somewhat-advanced effect (for the time) was actually done on the N64 (in this game) WITHOUT doing a secondary render-to-texture pass, which requires submitting the scene a second time to the GPU. Instead, the framebuffer was divided into small, tiled chunks (1/6 of its total size), with only a single small chunk getting updated per frame. This way, the amount of direct VRAM access from the CPU (which is typically slow as hell) is kept to a minimum within the duration of a particular frame, with multiple frames being required to update the entire screen. But anyway, she's starting to look and play incredibly well, and those of us with early access to the builds have been thoroughly enjoying revisiting this title on our favorite platform!

Physics-based Motion Retargeting from Sparse Inputs paper page: Avatars are important to create interactive and immersive experiences in virtual worlds. One challenge in animating these characters to mimic a user's motion is that commercial AR/VR products consist only of a headset and controllers, providing very limited sensor data of the user's pose. Another challenge is that an avatar might have a different skeleton structure than a human and the mapping between them is unclear. In this work we address both of these challenges. We introduce a method to retarget motions in real-time from sparse human sensor data to characters of various morphologies. Our method uses reinforcement learning to train a policy to control characters in a physics simulator. We only require human motion capture data for training, without relying on artist-generated animations for each avatar. This allows us to use large motion capture datasets to train general policies that can track unseen users from real and sparse data in real-time. We demonstrate the feasibility of our approach on three characters with different skeleton structure: a dinosaur, a mouse-like creature and a human. We show that the avatar poses often match the user surprisingly well, despite having no sensor information of the lower body available. We discuss and ablate the important components in our framework, specifically the kinematic retargeting step, the imitation, contact and action reward as well as our asymmetric actor-critic observations. We further explore the robustness of our method in a variety of settings including unbalancing, dancing and sports motions.

"Farm murders are a very serious problem in South Africa. The response to that is to say, 'Well, there are many problems in South Africa, so why are you pointing to this one?' But the fact of the matter is that it's a very unique problem, and it's a problem that could only be prevented or combated by a unique counter strategy. And there are a few things that make the farm murders unique. One is the extreme frequency at which it's happening - just the sheer numbers - thousands of people having been murdered on farms, many of them tortured. In many of those cases, nothing is stolen. They just come in, they torture the farmers for several hours, and then they leave. …The second is the brutality, the high levels of torture that we see. And any torture method you can imagine has been employed in these farm attacks. And it's the most grotesque torture you could think of in many of these cases. …The third is the unique economic impact, because farmers are skilled people, they are employers, they provide food for the country. So, it would have disastrous consequences for the nation at large, and it already has. The fourth is just the fact that farmers live in unique circumstances. They live far away from police stations, far away from their neighbors, oftentimes on dirt roads. Oftentimes there’s bad cell phone signals. So, that alone says that you need a unique counter strategy to fix this, even though the South African government doesn't want to recognize this. But then on top of this, what makes the farm murders exceptionally unique is that it's a very serious crime phenomenon that is also actively encouraged by politicians." - Ernst Roets

Congrats to EloShapes.com on their launch! On a similar note, is out of beta and available to the public. A lot of you have been asking me what my plan is now that EloShapes is also doing 3D scans... the answer is: nothing changed! I think that competition is good. I'm a mouse nerd and a LONG TIME EloShapes user, so the more options I get as a user, the better. I really think that my vision and EloShapes, though, is fundamentally different. I've had the domain for FMM for years, I have a much larger platform in mind compared to what I built so far. The 3D scans are the necessary step for my vision, not the end goal: they never were. I am also very proud of the fact that I've been able to scan at least 5 mice in full color EVERY DAY with my own pipeline, and I think I will easily have almost full coverage of the mice people would want on the website within months. Check the video for the mice I've added in just the last few days, all textured. Apart from some of the features I've mentioned before (like the virtual hand/grip), FMM is meant to be kind of a "MyAnimeList" for mice, so that you can share your profile, like this: and then later on leverage this curated list of mice you build for yourself to be shown even more mice you might like. FMM is also a tool for reviewers and anyone that wants to share their opinions on mice. Links like this: allow you to easily share your specific points about a mouse via the annotations, viewpoint sharing and measurements. And of course, as I've said since the beginning, I will use FMM to centralize all my hard testing about sensors, dpi, and such, so that you'll be able to find EVERYTHING about a mouse, including the raw results of my standardized sensor implementation testing. So, with this said, I will keep scanning as many mice as possible and adding as many features as possible until FMM becomes what I envisioned so long ago. Join my discord if you want to keep up! I hope you'll all give it a try! Ciao!

lando asked whether his relationship with oscar changed: “it's still the same. and i think we both are happy that that's how it is. it's because we both have a lot of respect for one another and we both understand the position that we're in. and we both treat the world of driving versus just personally what we're like away from the track, quite differently. that's how i've always been. i feel like i've always gone on well with my teammates since go-karting. i've always wanted to because it just makes my life more fun, more enjoyable and that's also why i'm here. it's because i love what i do, so the more i can do that, the better. but we still just very much understand that we're here, we work for mclaren, we want the best for the team. we work very hard and as drivers always do, you try and maximize your own performance more than anything. but then when we step out of the car, we can still have a joke. we still have laughs in our debriefs, and we still enjoy everything away from the track. so, no i think it's still better than ever in many ways. i think we're still very different people. he's very just calm down to earth, very relaxed, always looks just cool, and that's something i also admire quite a bit, is how just plain sailing he is with a lot of things. it's a good attribute to have. always hard to read what mood he's in, but i think probably for me, you see more visually kind of the moods i'm in. but otherwise, it's not like we go play golf together and do things like i have done with carlos, daniel i didn't play golf with. but we're still different people, but in terms of relationship, we get along well. we still work together well and i think it's still better than it's ever been”

Cameron Young is playing with a golf ball that would allegedly be compliant with the new roll back rules that will come into effect in a few years time. He was asked about it ahead of the PGA Championship and he says every player in the game is sacrificing distance for control, and he put it in play at the Wyndham last year which he won. “I think I put it in play the same reason that everybody else plays the ball that they play. I hit it during a ball test, one of the Titleist facilities probably close to two years ago and didn't know anything about it and just kind of say, hey, what's that one? Because I liked the flight. “Then as things progressed, I was able to test it last year at Wyndham, able to put that in play, and it's been there since. “Obviously there is no conforming list. I wasn't aware that it would have -- I suppose I read something that said it passed that test, but I wasn't aware of that until very recently. “So at no point was that a consideration. It was just really me trying to optimize my golf, and it's the ball that seems to work the best for me.” He then was asked whether he lost distance with it compared to other balls he’s tested: “Not particularly. I don't think any of us are out really here playing the ball that goes the farthest. I think you'd struggle to find a single person that's doing that. We're all sacrificing a certain amount of things that we feel are worth it, control with irons, control with wedges. For me, that's the biggest thing is being able to control spin, and this is the ball that does the best for me.” Finally he can as asked whether this ball goes further than the one he was using: “No, I hit very similar, yeah. It's much more -- the driver is kind of the easiest thing to deal with, I feel like. For me to get it where it needed to be, I had to just add a little bit of spin, and it kind of comes out at a perfectly playable range. “For me, the biggest thing, like I said, is the irons. This ball is easier to control with the irons. It doesn't spin as much, and it just allows me to be better with my distance control just because it's more consistent.” The golf ball rollback has been a hugely controversial subject but Cameron Young is currently using one that’s compliant and he is playing the best golf of his career. This gives the best idea yet on what impact, or lack of it, the new rules will actually have on the sport. PGA Championship
