    LiveSplat is a system for turning RGBD camera streams into Gaussian splat scenes in real-time. The system works by passing all the RGBD frames into a feed forward neural net that outputs the current scene as Gaussian splats. These splats are then rendered in real-time. I've put together a demo video at the link above.

    I'm the co-creator and maintainer of https://aframe.io/ and long time Web 3D graphics dev. Super excited about new techniques to author / render / represent 3D. Spark is a an open source library to easily integrate Gaussian splats in your THREE.js scene I worked with some friends and I hope you find useful. Looking forward to hearing what features / rendering techniques you would love to see next.

    Hi HN, author here. SHARP is Apple's recent single-image 3D Gaussian splatting model (https://arxiv.org/abs/2512.10685). Their reference code is PyTorch + a pretty heavy pipeline; I wanted to see if it could run in a browser with no server hop, so I exported the predictor to ONNX and ran it via onnxruntime-web with the WebGPU EP. What works: drop in an image, get a .ply you can download or preview live, all on your machine — your image never leaves the tab. The model is large (~2.4 GB sidecar) so first load is slow on a cold cache, but inference itself is a few seconds on…

    I ported Microsoft's TRELLIS.2 (4B parameter image-to-3D model) to run on Apple Silicon via PyTorch MPS. The original requires CUDA with flash_attn, nvdiffrast, and custom sparse convolution kernels: none of which work on Mac. I replaced the CUDA-specific ops with pure-PyTorch alternatives: a gather-scatter sparse 3D convolution, SDPA attention for sparse transformers, and a Python-based mesh extraction replacing CUDA hashmap operations. Total changes are a few hundred lines across 9 files. Generates ~400K vertex meshes from single photos in about 3.5 minutes on M4 Pro (24GB). Not as fast as…

    Hello HN! I’m excited to share this open-source community mashup showing the power and possibility of combining 3D Gaussian splat scans with traditional mesh-based 3D tiles maps in the browser. As you've probably seen on HN a bunch lately, Gaussian splats are a new method to allow custom 3D scans of scenes and objects [1] and Google Maps 3D Tiles API are the same 3D buildings and street views your familiar with in Google Earth or Google Maps, and recently they’ve been made available for inclusion in web apps. Combining splats + 3d map mixes highly detailed real-world custom micro-scans with…

    I just launched SplatGallery, a platform where you can share and discover the best 3D models created with Gaussian Splatting. It's a super early stage and new models are coming it fairly often. Would love to get feedback from the HN community on how to improve it!

    This is a GPU "software" raytracer (i.e. using manual ray-scene intersections and not RTX) written using the WebGPU API that renders glTF scenes. It supports many materials, textures, material & normal mapping, and heavily relies on multiple importance sampling to speed up convergence.

    3D-to-photo is an open source tool for Generative AI product photography, that uses 3D models to allow fine camera angle control in generated images. If you have 3D models created using the iOS 3D scanner you can upload them directly on to 3D-to-photo and describe the scene you want to create. For example: "on a city side walk" "near a lake, overlooking the water" Then click "generate" to get the final images.

    I was playing with this for a few weeks over the holiday break. This is one of the GS3D sample scenes running on PCVR at about 65 FPS. I'm sorting on the CPU at the moment, so there are some hitches, but it works! I may publish this as a Unity asset. (I'd love to get it working on Vision Pro, but we'll see.)

    Last week I wanted to quickly view some Gaussian splats which I had trained on a remote server that didn’t have any open ports or a display device. So I ended up downloading everything locally just to inspect the results This weekend I put together a terminal-based Gaussian splats viewer that renders directly in the terminal. It works over SSH and currently runs on CPU only and written in rust with claude code. I’ve found it to be pretty useful for quickly checking which .ply files correspond to which scenes and getting a rough sense of their quality. Along the way, I also wrote a small…
