What if you could npm install 3D models? Introducing Vibe3D - the shadcn for threejs Starting with the scifi asset kit, over 180+ models, all free and oss (MIT licensed) and two reference terrain meshes. All models are installed directly into your codebase instead of pre-packaged as code imports or worse yet, FBX files 🤮 Docs: This means, a simple "bunx vibe3d add Artificial Intelligence Papers-kit/pressure-gauge" will install the fully procedural code Want to change something? just tell your ai to do it It uses some shared helper code to produce the topology and at least per kit all items reuse and share the same materials, so technically performance should be better than letting your ai run wild on its own. Also releasing with it two skills: - Vibe model skill to produce your own models and kits, just "bunx vibe-model --global" and tell your ai to vibe model some 3d assets with a reference photo, you'll see it works - Vibe terrain "bunx vibe-terrain" installs the terrain mesh modeler, yea just try it out, best results with opus 5 ngl Everything is MIT licensed, i was just joking, no hate for unreal or unity Threejs still the best tho 🖕🏻 If you just want to see all 3D models up close: Yea, you can also just vampire it and download all modes as .glb files, good luck fixing some of them then though Big thanks to ThreeJS Assets for contributing 50 assets to the scifi kit! Everyone who spends some tokens on it will be added to the contributor list Oh and before i forget fuck you kenney, we roll our own kits now

Testing one of the best safety features of an airplane, the “Enhanced Ground Proximity Warning System” (EGPWS, pronounced E Gyp-Wiz). It’s part of every preflight check. Sound on! It’s a warning system. While the jet has separate warnings for things wrong internally, EGPWS is concerned about what’s outside the jet, not what’s inside. It’s primarily concerned w/ terrain & obstacles…EGPWS can “see” outside when pilots can’t. It doesn’t actually see anything, though. There are no cameras or lasers. EGPWS does use the jet’s radar, but not for detecting terrain. (We’ll talk more about radar in a minute, but it’s not useful for orienting yourself to terrain in the vertical. It has a “map” mode that you can use to “paint” things like cities, lakes & shorelines, but it only knows how strong the reflection is & how far away, not how high. We almost never use it in map mode, anyway) EGPWS uses the jets navigation systems – like GPS, Inertial Reference, Altimeters, airspeed, etc. – to plot a position in a virtual world. This world is contained in a database on the jet; it’s constantly plotting your position & then estimating where you’ll be in the next few minutes if the trend continues. The virtual world database knows where the mountains are. When you get close to airports in the database (not all airports are in it), it knows where the buildings & antennas are, too, out to a certain radius. Past that radius, it stops caring about the manmade objects. Anyway, it can tell if you will hit something on your current trend & will issue various warnings. It can give you up to 60 seconds of warning. It starts out slow, like saying “CAUTION, TERRAIN”, but if you don’t fix it, it gets serious…“TERRAIN, TERRAIN, PULL UP!”. You’re 20-30 seconds from impact. It’s not a miracle worker, though. It can wait to give you a warning that you can’t fix. Imagine flying toward a 10,000’ high cliff at 1,000’. A 60 second warning will not be enough time to climb 9,000’ & clear it. Or, it sees a mountain to your right, but your current path is clear. It doesn’t know you’ll do a 90° right turn once abeam the mountain. Now you’ll get some late warnings. EGPWS has various other functions. If you get on the approach but haven’t configured to land, it will say “TOO LOW, FLAPS” (or GEAR). If you start getting below the glidepath, it will say “GLIDESLOPE”. Start descending right after takeoff? “DON’T SINK”…and if you do keep sinking, it switches to “PULL UP!” Now, EGPWS doesn’t use the onboard Doppler radar for any of these functions, but it does use it to detect windshear. EGPWS doesn’t care if you turn on the radar or not, it turns it on itself when you push the throttles up for takeoff or when you descend below a certain altitude on approach. It takes about 12 seconds for the radar to build a picture from that point, but once it does, it can “see” windshear. The Doppler detects this by bouncing radar off of particulates & reading how they are moving at different altitudes. The particulates can be dust or just humidity…the radar can’t read air molecules by themselves. So, it’s still possible to get windshear the radar doesn’t see on very dry, clean days. EGPWS hates windshear. If it detects it, EGPWS replaces your screen w/ the radar – even if not turned on by you – & starts with a gentle warning to “MONITOR RADAR DISPLAY”. If you get closer to it, you get “WINDSHEAR AHEAD” (on takeoff – abort if you still can) or “GO AROUND, WINDSHEAR AHEAD!” (on landing). EGPWS is great, but can’t actually move the jet. It’s not connected to the controls in any way. Some fighters do have that capability, but not airliners. The pilots have to fix it. OK, that’s a brief summary of EGPWS. As usual, I’m dramatically simplifying things for a non-techie audience…there is much more to it & different models of jets have slight differences in how this all works. The 737 MAX has some improvements, w/ different voices & even panic, but I don’t have one to record, sorry!
