Hi3D, formerly known as Hitem3D, is a high-precision AI-powered 3D model generation platform developed by MathMagic. By simply uploading a single image or multiple images from different viewpoints, users can automatically generate ultra-high-resolution 3D models with a resolution of up to 1536³. The generated models can be widely used in 3D printing, industrial design, game development, film and video production, digital twins, and many other fields. Its proprietary Sparc3D algorithm adopts sparse convolutional networks and 3D VAE technology, significantly reducing the information loss that often occurs in conventional conversion methods. This enables highly accurate and efficient 3D generation while preserving fine details. Hi3D can generate high-precision models in as little as 2 minutes and also supports advanced parameter adjustment for experienced users. In addition, the platform provides a one-stop workflow covering image editing, model generation, repair, post-processing, and 3D printing, supporting the next generation of 3D content creation.
