What is the technical architecture of Hitem3D?

Hitem3D adopts a self-developed dual-engine system, combining high-resolution geometry generation with efficient local attention processing to ensure the geometric accuracy and texture consistency of 3D models, enhancing rendering quality and generation efficiency. The system includes two core engines, Sparc3D and Ultra3D, which are respectively responsible for detail-rich geometric construction and efficient local feature processing. The technology covers structure-aware texture generation, Physically Based Rendering (PBR), lighting semantic recognition, and automatic retopology, effectively reducing light and shadow interference and accurately restoring material properties. In addition, the platform supports an open API (automation mainly refers to the automation of the generation process; the generated results still require manual inspection and necessary post-processing) and is compatible with mainstream modeling software such as Blender, Unity, and Maya, facilitating integration by enterprises and developers to meet multi-scenario collaboration needs.
