The general goal of any 3D capture or creation technique is to extract a 3D representation of a scene. It is possible to distinguish between 3 major approaches
- 3D acquisition: This refers to the direct capture of a 3D scene using either a multiview or image+depth based camera setup.
- 2D to 3D conversion: The goal of this approach is to recover the 3D scene strcuture from a monoscopic image or video.
- 3D rendering: Given a 3D model
