24 alternatives to TRELLIS 3D AI
Hi HN! I've built TRELLIS 3D AI, an open tool that converts 2D images into professional 3D assets using advanced AI technology. Technical Implementation: - Browser-based processing using WebGL - Structured LATents (SLAT) for maintaining geometric integrity - Dual output pipeline generating both GLB and 3D Gaussian formats - Real-time 3D preview using Three.js - Optimized for processing images up to 2048x2048px The core technology combines: - Pretrained vision encoders for image understanding - Rectified flow transformers for 3D geometry generation - Advanced neural networks for texture…

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…

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.

Hey HN! I’m Zach one of the co-founders of Adam (https://www.adamcad.com). We're building AI-powered tools for CAD and 3D modeling [1]. We’ve recently been exploring a new way to bring GPT-style image editing directly into 3D model generation and are excited to showcase this in our web-app today. We’re calling it creative mode and are intrigued by the fun use cases this could create by making 3D generation more conversational! For example you can put a prompt in such as “an elephant” then follow it up by “have it ride a skateboard” and it preserves the context, identity and…

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. The tech stack behind 3D-to-photo: Handling 3d models on the web: @threejs Hosting the diffusion model: @replicate 3D scanning apps: shopify,Polycam3D or LumaLabsAI

I’m a Technical Artist. I built anyCreature, an open-source, mesh-based generative harness designed to programmatically quantify and enforce 3D aesthetics through three automated pipeline checks: 1. QC Thresholds: Automated pass/fail checks for standard game-engine specs (poly count, vertex budget, rigging, and animation tracks). 2. Quantified Aesthetics: Spatial vertex analysis to objectively measure mass distribution and form tension, ensuring biologically logical anatomy. 3. Silhouette & Readability: Automated high-contrast B&W renders and 24px thumbnail tests to guarantee visual…

It's our new text-to-image model: a 9.3B single-stream diffusion transformer trained entirely from scratch. We focused heavily on controllability through structured JSON prompts, with strong text rendering, spatial awareness through bounding box guidance, and color palette control. It has the best text rendering of any open-weight model we've tested so far, and the NF4 quantized checkpoint runs on a single 24GB GPU. For more technical details and examples see our blog post: https://ideogram.ai/blog/ideogram-4.0/ We will be happy to answer any questions :)

I built a browser-based port of fogleman/primitive — a Go CLI tool that approximates images using primitive shapes (triangles, ellipses, beziers, etc.) via a hill-climbing algorithm. The original tool requires building from source and running from the terminal, which isn't exactly accessible. I compiled the core logic to WebAssembly so anyone can drop an image and watch it get reconstructed shape by shape, entirely client-side with no server involved. Demo: https://primitive-playground.taiseiue.jp/ Source:…
