Gghead
Overview :
GGHead is a 3D Generative Adversarial Network (GAN) based on 3D Gaussian scattering representation, designed to learn 3D head priors from a collection of 2D images. This technology simplifies the prediction process by leveraging the regularity of the UV space of template head meshes to predict a set of 3D Gaussian attributes. Key advantages of GGHead include high efficiency, high-resolution generation, full 3D consistency, and real-time rendering capabilities. It enhances the geometric fidelity of generated 3D heads through a novel total variation loss, ensuring that neighboring rendered pixels originate from close Gaussian points in UV space.
Target Users :
GGHead targets 3D modelers, animators, game developers, and virtual reality content creators. These users typically require a fast way to generate high-quality 3D head models, and GGHead provides an efficient, consistent, and realistic solution for 3D head generation that meets their dual demands for speed and quality.
