Volumetric video

Volumetric video captures a three-dimensional space and performance, creating a navigable, interactive 3D model with six degrees of freedom (6DoF) for AR/VR applications.

Volumetric video is a sophisticated media production technique: it captures a real-world subject or scene using an array of synchronized cameras and depth sensors, then processes the data into a dynamic 3D mesh or point cloud. This process delivers a true 6DoF experience, allowing the user to move around the recorded content, not just look around from a fixed point, which is the key difference from 360° video. Major players like Microsoft Mixed Reality Capture Studios and Intel Studios (with its 5K camera arrays) are driving its adoption. Applications are already live in enterprise and entertainment: we see it in sports replays (free-viewpoint highlights), immersive training simulations (e.g., medical), and high-fidelity AR/VR content.
