CSM AI

Hi3D is an AI-powered 3D generation platform that transforms images into high-quality, production-ready 3D models for creators, designers, engineers, and 3D printing professionals. Built on the Sparc3D × Ultra3D engine, the platform focuses on generating clean geometry, preserving sharp edges, reconstructing hidden surfaces, and delivering realistic textures suitable for professional workflows. Users can upload a single image or multiple views and generate detailed 3D assets with accurate structure, human-like realism, and high-resolution PBR textures. Hi3D supports a wide range of use cases including 3D printing, game design, animation, film production, architecture, sculpture, fashion, jewelry design, and product visualization. The platform includes specialized features such as AI texturing, 3D relief generation, multi-color model segmentation for 3D printing, portrait-focused 3D reconstruction, and de-lighted texture generation.

This 3D avatar diffusion model is an AI system that automatically produces highly detailed 3D digital avatars. The generated avatars can be freely viewed in 360 degrees with unprecedented quality. The model significantly accelerates traditionally sophisticated 3D modeling process and opens new opportunities for 3D artists. This 3D avatar diffusion model is trained to generate 3D digital avatars represented as neural radiance fields. We build on the state-of-the-art generative technique (diffusion models) for 3D modeling. We use tri-plane representation to factorize the neural radiance field of avatars, which can be explicitly modeled by diffusion models and rendered to images via volumetric rendering. The proposed 3D-aware convolution brings the much-needed computational efficiency while preserving the integrity of diffusion modeling in 3D. The whole generation is a hierarchical process with cascaded diffusion models for multi-scale modeling.
