Medical Surgery VRBrain & Anatomy Trainer

Medical Surgery VR is a cutting-edge virtual reality training and visualization application built in Unity 6 with the Universal Render Pipeline (URP), designed to bridge the gap between medical education and immersive technology. The experience is structured around two purpose-built scenes: a fully dressed hospital operating room for hands-on surgical simulation, and a dedicated Brain Deep-Dive environment for in-depth neurological inspection.

In the main surgical scene, users interact with anatomical models placed on an operating table inside a richly detailed hospital room. A fully custom Bounding Box Manipulation system—implemented from scratch with 8 corner scaling handles and 12 edge rotation handles rendered via a real-time LineRenderer wireframe—lets physicians grab, scale, and rotate anatomy models in 3D using XR Interaction Toolkit controllers. A Hologram / X-Ray toggle, backed by a custom URP shader and UI Toggle integration, can instantly convert any mesh into a semi-transparent hologram, revealing internal structures on demand.

The surgical component uses EzySlice for real-time mesh cutting, driven by a physics-accurate ScalpelSlicer that detects trigger contact with sliceable anatomy and splits the mesh along the scalpel’s cut plane. Each resulting hull receives a procedurally generated cross-section material, a convex MeshCollider, and a configured Rigidbody; the lower piece is kept kinematic while the upper piece is released to gravity after a brief delay to avoid interpenetration. A SliceManager supports fully resetting the specimen back to its original state via a simple UI action.

The Brain Deep-Dive scene provides a dedicated neurological inspection mode. Users orbit freely around a high-fidelity 3D brain using the left joystick for horizontal and vertical orbit around the brain’s pivot, while the right joystick controls zoom distance. On the right controller, button A activates holographic scan view—swapping all brain materials to a glowing hologram shader—while button B restores the original anatomical shading, enabling rapid switching between modes for teaching and demonstration.

Built on OpenXR for cross-platform compatibility and AR Foundation for future AR expansion, Medical Surgery VR showcases the convergence of medical science and real-time 3D technology, delivering a training tool that is both technically rigorous and deeply immersive.
