Thanks to @mrdoob, three-gpu-pathtracer now includes a drag-and-drop viewer for binary glTF files 🚀 I've added a link to the viewer in the repo! #threejs #webgl #raytracing

@ggsimm @sweriko @Kirschdieb Sent privately to avoid quality loss😁

@ggsimm Can’t wait to use it with my impostor lib ❤️

@bandinopla @threejs Good idea 💡

@agargaro_dev @threejs try to add something to allow for somehow be able to identify which instance is from what geometry, in case one needs to move some instances of a particular instance mesh. Example: rock[5] is animated to float, but rocks are now merged into a batched mesh. So how to find rock[5]

Created a pull request in @threejs to add an example on how to combine many InstancedMesh into a BatchedMesh + LODs. This is useful when you do an environment that shares many duplicated props of different kinds but using a common atlas material. github.com/mrdoob/three.j…

With WebGPU, AAA graphics on the web isn’t a dream anymore. Devs just need native-grade tools. That’s why I’m building Three.js Plus. Today I added GPU culling. Here 5M PBR cubes distributed in <10ms on a convex geo, running at 120fps thanks to object culling & indirect draws.

@onirenaud @MaximeHeckel I'm really impressed with your work! My library (InstancedMesh2) performs frustum culling on the CPU, which can be accelerated using a BVH. I was starting to study webGPU so I could migrate the library. It would be great if you could give me some advice😁

@MaximeHeckel I'm not sure which type of magic did agargaro here but it's technically impossible to cull instances in the GPU using WebGL. You need access to an indirect storage buffer and use indirect draw calls, common GPU features introduced to the web via WebGPU.

I did something → samsy.ninja Sound on & bring friends with you. Open to new opportunities. WebGPU @threejs

@ashimilation Yes, this is the article :) shaderbits.com/blog/octahedra…

@agargaro_dev Is this the same method fortnite itself uses? I noticed its at the very least quite similar (plus the example being the fortnite tree aswell LOL) ALSO great choice of a pfp, gotta love the english gentleman

This tree is only 2 triangles

@DehFanBoy_ @sweriko There is a significant performance gain, but you need to be careful about overdraw. I use these impostors as LOD from high distance. You can check this demo: octahedral-impostor.vercel.app

@sweriko @agargaro_dev How much does this method impact perf?

@MarikoRawralton @sweriko It's also possible to use an octahedron instead of hemi-octahedron

@sweriko @agargaro_dev Is there a reason it couldn't be done from below? It kinda falls apart if you're close to the tree from a lower angle.

@BrianBreiholz @threejs @VIVERSEofficial It's truly incredible what you've done 😍 Congratulations, my friend!

Excited to announce that I've shipped my first game! Written from the ground up in @threejs in 3 months and published on @VIVERSEofficial Some tech stuff that I'm really proud of: - fully custom spherical harmonics prt lighting. Giving a baked diffuse look while still allowing for dynamic objects - Runs completely inside a WebWorker (rendering & simulation) using OffscreenCanvas - Supports all input types: desktop, mobile, gamepad (non-trivial if your app runs in a worker!) - No Postprocessing! No bloom - everything you see is faked via mesh based shaders for performance reasons Huge thanks to @VIVERSEofficial who have made this possible by letting me into their Creator Program. It's not easy to make a living off gamedev on the web yet, so this is great for the ecosystem. All links below: #VIVERSE #threejs #IndieGameDev

@dghez_ @sweriko He’s using part of my library, he tagged me in the comment :)

@sweriko @agargaro_dev

@lambdanthony @sweriko Me too bro

@agargaro_dev @sweriko I love you

@lambdanthony @sweriko There’s my demo here github.com/agargaro/octah…

@agargaro_dev @sweriko Do you have a public repo available for this? I will love you forever

@hm_no_1 Yes we can try, write me in private :D

Playing with my octahedral impostors library 🤓 There are still things to improve, should I continue? I created a demo with a terrain 3072 x 3072 and 200k trees. It should work on mobile too! Demo: octahedral-impostor.vercel.app Github ⭐️: github.com/agargaro/octah… #threejs #webgl

@sweriko Happy to help😁 My implementation is based on those of Unity and Godot.

Its an Octahedral Impostor, basically like a traditional camera-facing billboard, but as it rotates, it samples pre-rendered views of the original 3D model from a texture atlas based on the viewer’s angle. Thank you @agargaro_dev for the help!
