Hey there new #threejs devs, vibe coders, and creative tinkerers 🎮✨ I’m the guy who made Mario Kart in JS... and yeah, it was terrible. 😂 But I learned a lot since, so here are 5 lessons I wish I knew before: 🧵👇

1. Use lerp, always. Linear interpolation is your best friend for smooth movement. Don’t just add numbers to rotation or position. It’s the secret sauce for natural transitions, especially for car turning, camera follow, and anything that moves.

2. R3F is awesome but know its limits. React Three Fiber is powerful, and I still love it. But keep React out of your 3D rendering logic. Seriously. Use React for UI only. React-re render doesn't do well with Three.js frame loops. use Ref object.

3. Keep an eye on your draw calls. 👀 Every draw call hits your performance, and they add up fast. At first, you won’t notice. Then suddenly your scene’s lagging and you’re wondering why your 30 cubes are killing the FPS. (Hi @levelsio) Batch stuff. Merge geometries. and...

4. Use Instances! With three.ez/instanced-mesh and InstancedMesh2, adding, updating, and modifying instances in real time is super smooth and super easy. You can go really far even give each instance its own shader. 🔗

5. Have fun. Game dev is so much fun. I’ve lost hours just tweaking things... or honestly, just playing my own game. It's so cool to do !

The tweet is doing Numbers ! Might do a part two 👀

invy on the biggest lessons he has taken since joining Paper Rex: "I guess I've learned to trust myself more and be confident in my decisions. From the teams I came from, it's more of a strict structure, so you have to follow protocols. But here, I'm just more confident in the decisions I make because I know they trust me and I trust them if I make a mistake. And I guess honestly, I learned a lot from all of them. Their mechanics are insane. So I learned how they peek and everything, and I also implemented it."

".50cent wasn't there but we got into a shootout with his armed security in New York. We had a lil back and forth with firearms. Yeah I was in it man but I was telling you before, it takes you a lot of time to undo things that are second nature man." - The Game

2023 was a year that I was scammed, hurt, cried a lot, frustrated, and learned a lot and grew up. It was a year where there were many good things and bad things, but I would like to thank those who were always by my side and support me. Happy New Year, everyone.🙏🏻💕✨

Archie Kalokerinos was an extraordinary doctor who in 1957 chose to devote himself to helping the Aboriginees in Australia. There he discovered: •Vitamin C deficiency killed a lot of people. •It made vaccines much more deadly. These interviews are profound and I learned a great deal from them so I am including them in a thread since they are hard to find online. I've tried to summarize the key points from each part🧵

SAKURA’s moving message on live Weverse "There was a lot going on, but personally I cried a lot and there must have been a lot of things I didn’t know. In fact, I cried a lot just before LE SSERAFIM ’s debut and during my time as LE SSERAFIM . I cried more than before, and maybe it’s because I worked hard and was sincere, but there were also things like that, and I remember laughing a lot, and my range of emotions expanded a lot while I was doing LE SSERAFIM . There are so many things that make my heart tremble. Whether it’s good or bad. It seems that there are many different memories. I’m sorry, I didn’t realize how difficult it was until you could talk about it calmly. I know you can’t always be happy, but I hope you can be."

(the longer version of the rose story) Sh: oh, there is a rose in our room! I didn’t mean to show it to you guys (joking), but JS went and bought it secretly for me. I got it as a gift from JS, you have to tell them. JS: there is a smoking room in the first floor of our hotel, I went there to smoke and found that there is a flower shop beside it. After I saw the shop I went to smoke and was thinking “should I buy him a flower?”. After I finished smoking, SH was totally absorbed in his phone so I went immediately to the flower shop and bought one rose and gifted it to him. SH: It’s been a very long time since I received flowers, because of Mangchi JS: yes that’s right, it’s difficult to give him flowers because we have Mangchi at home so I thought you’d be happy to get flowers since we are on a trip SH: I’ve said that a lot, when we are going somewhere and see couples on a date I’d be like “oh that couple, they got flowers” JS: SH was so happy to receive the flowers that he bought me a lot of clothes. So I was like “I will gift you a rose in a different color each day” and SH was like “then I will buy you every color of this clothes” 😂❣️

Jeremiah Fears talking about how he knew he was leaving college early and he believed he was going to be a top 5 draft pick “Once I got there, I think I still got the text. I text my dad like the second week. I was like, Man, I’m going top 5. He was like, You think so? I said, I know. So, but just the work I put in and then I was seeing it translate in practice. I was doing my thing in practice and then in the scrimmages we played like two of the top five teams, top three teams in the country preseason and I did my thing. I’m like, Yeah, I’m going top 5” (Via Club520podcast)

Soyeon: It doesn’t feel real that it is my second time receiving this award. Back when I was a trainee, there was no songwriting lessons for female trainees. But recently, there are a lot of new female artists who are writing songs, so I hope this award gives them some encouragement

260626 Doyoung’s Instagram Story Update #DOYOUNG #도영 Czennies, have you been well? I’m doing well and staying safe. It’s been a while since I last shared any news. I wanted to show you me singing the song ‘Goodbye, My Love’ so I looked over the lyrics a little more, listened to it a lot, practised, and then sang it. But after enlisting and spending time here, I’ve thought more than once, “I’m really glad I sang this song before coming.” I also feel sorry that I couldn’t express more before I came, I worry about whether you’re doing well, and I’m living while making promises to myself for the days ahead. I miss you a lot. Really, really a lot. I’m so thankful, and I miss Czennies so much. I recorded a few more songs here and there before coming in, so whenever they come out, I sincerely hope they’ll be songs that give you strength in some way. Thank you for today too!

"...I made it seem like it wasn't that bad or wasn't that big of a deal, but I was fucking terrified and it was really hard and every single day that I spent in that terrible fucking place, every single day I wish that I was right here where I am right now..." 📹: 𝒜𝓃𝓃𝒾𝑒 💖⭐️

Phuwin thought he got caught again, but it turned out the fans had mistaken someone else for him. I’M LAUGHING SO HARD 555555 THE GOOD YEAR OF POND #Happy25thPondDay 🐼: Actually, I have a funny story to tell. It happened just now, before I got here. 🐻: Really? What happened? 🐼: When I was coming through The Mall… I already knew the traffic would be bad because today is early voting day, so if you have time, go vote too. Anyway, the traffic was a bit slow, but I arrived pretty fast. The problem was that inside the mall, it was super crowded. At first, I was going to park upstairs, but going up floor by floor took too long. Then I saw a spot downstairs and parked there, thinking I was being smart. I thought, “If I take the elevator inside the mall, I’ll come out right at the hall and everyone will see me, right?” So I decided it would be smarter to take the parking lot elevator. 🐻: From the parking lot? 🐼: Yeah. I pressed the button for the third floor. When the doors opened, there were lots of people sitting right in front. Luckily, everyone had their backs to me. So I thought, “I’m screwed.” I pressed the second floor, turned around, and closed the door. Suddenly, the people in front started standing up, and I heard, “Hey, Phuwin! Phuwin!” In my head, I was like, “Oh my God, I’m done for, they found me again.” I was thinking, “What do I do now?” I always end up embarrassing myself like this. But then I looked again and realized… They thought some random guy walking in the mall was me. And everyone started going, “Look, Phuwin is here! Phuwin is here!” At that moment, I just wanted to say: “Guys, I’m right here behind you!”

🦊 i revealed the tracklist myself and there are six songs, out of which i participated in making 5 songs 🦊 i worked on them for a really long time, i think it was a couple of months 🦊 i really beat my brains while working on it 🦊 but i think it came out well and since it was a solo album, i was able to capture a lot of original expressions, emotions and vibes so i really liked that 🙂‍↕️
