Charactergen
Overview :
CharacterGen is an efficient 3D character generation framework that can generate high-quality and consistent-looking 3D character meshes from a single input image. Using a streamlined generation pipeline and an image-conditioned multi-view diffusion model, it effectively aligns the input pose to a standard form while preserving key attributes from the input image, addressing challenges posed by diverse poses. It also employs a transformer-based universal sparse view reconstruction model and a texture back-projection strategy to generate high-quality texture maps.
Target Users :
CharacterGen is designed for animators, game developers, and 3D artists who need to quickly generate 3D character models. It boosts productivity by reducing the manual modeling and texture mapping workload while ensuring high-quality and consistent character models.
Use Cases
Animation studios use CharacterGen to quickly generate 3D character models for their animations, shortening production cycles.
Game developers utilize this technology to design and generate 3D models for new game characters, enhancing the game's visual appeal.
3D artists employ this framework for personalized character creation, used in art exhibitions or personal portfolios.
