Hi3D vs Unique3D

Hi3D is an AI image-to-3D tool that turns images into models using Math Magic’s Sparc3D and Ultra3D models. It supports both single-image and multi-view generation, along with text-to-3D, AI texturing, 3D relief generation, and a tool for dividing characters into printable parts. Exports include FBX, GLB, OBJ, STL, and USDZ, and models can be sent directly to Bambu Studio and OrcaSlicer. The wider integration list includes Snapmaker, Creality Print, ElegooSlicer, ComfyUI, and Blender. Developers and enterprises can use its Open Platform API; API operations are priced by model and resolution, with one credit listed at $0.020. The Free plan includes 100 lifetime credits, up to 10 asset generations, one concurrent task, and storage for seven models; those models are public under CC BY 4.0. Paid plans include private and commercial use, and the listed pricing note says paid plans start at $19.90/mo. Hi3D Scan supports video capture or gallery upload for model reconstruction. Platforms include Android, iOS, web, and API.

Unique3D generates textured 3D meshes from a single image. Its method derives four orthographic views from the input and progressively increases their resolution, then generates matching normal maps with a normal diffusion model. The project's ISOMER reconstruction algorithm combines color and geometric priors and can produce meshes with millions of faces. The project describes generation from a single-view image in 30 seconds and says a high-fidelity textured mesh from one orthogonal RGB image can be generated in under 30 seconds. Image-to-3D and AI texturing are listed capabilities, and GLB is the listed export format. The repository links to a ComfyUI implementation and provides instructions for an interactive local Gradio demo after model weights are downloaded. An online demo is free to try with a registration invitation code; it is described as slower but more stable than the Gradio demo. The Linux setup targets Ubuntu 22.04.4 LTS and CUDA 12.1, while Windows installation may require Visual Studio Build Tools.
