Show HN: Trellis 3D AI – Turn any image into 3D assets using AI

3 points by yangxiaobo - 219 Days, 0 Hour ago Hacker News

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 mapping

Current Specs: - Processing time: ~30s per image - Output formats: GLB + 3D Gaussian - Zero external dependencies - Runs entirely client-side

Currently it's using Hugging Face for processing, and I plan to implement API integration in the future to enable more advanced features.

Would love your feedback and suggestions for improvements.
