Development of a Layer-Based Interactive 3D Human Anatomy Visualization System

I am a student, and I want to develop a 3D educational application for studying human anatomy, as part of my diploma project, primarily aimed at students. The main goal of the program is to allow users to interactively explore the human body by selectively viewing different anatomical systems and organs.

Specifically, I want the application to support the following features:

A high-quality 3D human body model that represents realistic anatomical structure.

The ability to toggle visibility of individual anatomical layers, such as:

  • Skin

  • Muscles

  • Skeleton

  • Veins and arteries (circulatory system)

  • Organs (heart, lungs, liver, etc.)

  • Brain and nervous system

The option to view a single system in isolation (for example, only veins or only the brain).

The option to combine multiple systems at once (for example, organs + veins, or skeleton + muscles).

The ability to change the appearance of the model dynamically, such as:

  • Adjusting transparency of layers

  • Highlighting selected organs or systems

  • Changing colors for better visualization and learning

Interactive controls to:

  • Rotate, zoom, and pan the 3D model

  • Click on an organ or system to display its name and educational information

A user-friendly interface suitable for students, focused on learning and exploration rather than medical diagnostics.

I would like to understand:

  • Whether this kind of system is technically feasible with modern 3D technologies

  • What tools, engines, or libraries would be most appropriate (for example, WebGL/Three.js, etc.)

  • What are the main technical challenges, especially related to performance, model complexity, and real-time layer switching

  • Best practices for organizing anatomical data so that individual systems can be easily shown or hidden

Additionally, I would like to know where I can obtain accurate and legally usable medical/anatomical 3D data, such as:

  • Complete 3D human body models

  • Models that are already separated into anatomical layers (skin, muscles, organs, vessels, nerves, etc.)

  • Open-source, academic, or commercial datasets suitable for educational use

  • Common file formats and data standards used for loading such anatomical models into a 3D application
