MIDI-3D is based on multi-instance diffusion modeling technology, which enables end-to-end generation from a single image to a complete 3D scene. By combining artificial intelligence and 3D modeling technology, the tool is able to process all identified objects in a picture at once and automatically maintain the spatial relationship between them. Its 40-second generation speed achieves an exponential increase in efficiency compared to traditional 3D modeling, which requires handcrafting objects one by one.
Specifically, the system realizes batch generation through the following technological breakthroughs:
- Image segmentation using Grounded SAM for accurate labeling of each object region
- Generate all 3D object instances in parallel using multi-instance diffusion models
- Automatic scene combination and spatial relationship alignment
Developers have verified that for a typical indoor scene with 4-5 objects, traditional modeling takes 8-10 hours, while MIDI-3D outputs a complete scene file in .glb format in just 1 minute.
