Question: Is there a comprehensive digital atlas that offers detailed 3D representations of the human body and its systems?

If you want a digital atlas that can give you a detailed 3D view of the human body and its systems, BioDigital could be a good choice. This cloud-based service offers an interactive 3D model of the human body that can be used on any device. It includes more than 600 health conditions, works with web and mobile apps, and can be used in virtual reality and augmented reality formats. BioDigital is intended to help people understand anatomy, disease and treatment, so it's geared for education and medical professionals.

Another good option is VOKA, a detailed 3D anatomy and anatomical pathology atlas. VOKA is an interactive service with a full 3D atlas of human anatomy for male and female bodies, along with a large 3D pathology catalog. It also includes interactive 3D models with zooming, rotating and isolating features, and supports multiple languages. The service is geared for students, professionals and institutions, offering a deep learning experience and frequent updates with new content.

If you want something a bit different, check out Meshcapade, which uses patented foundation models and scientific knowledge to create digital human avatars. The service is designed to let digital humans move and act naturally, with a generative model called SMPL. It can create photorealistic digital avatars from text prompts, video and images, and could be useful for e-commerce and the metaverse.

Although not specifically focused on the human body, 3DFY.ai offers an AI-powered system for generating 3D models from text prompts or single images. It's a flexible system for creating 3D assets, which could be useful for health care, for example, with simulation and education applications that can quickly and easily produce detailed and realistic models.
