FVV is Voxelogram’s ‘Free-Viewpoint Video’ file format.



FVV is Voxelogram's 'Free-Viewpoint Video' file format. While in traditional 2D video the viewpoint is fixed by the single camera used to capture the scene, in Free-Viewpoint Video the user can interactively choose arbitrary viewpoints of a real captured scene while the video is playing back. The scene therefore is captured by multiple synchronized video cameras and the shape and appearance of the captured actor is reconstructed from the multi-video streams using Voxelogram's 4CAST software framework.
Like traditional 2D video files a Free-Viewpoint Video file consists of a sequence of frames, together with some descriptive information. Unlike 2D video however, which basically only contains pixel data per frame, a Free-Viewpoint Video frame contains geometry and texture information. Using the FVVLib an application can access the FVV files and play it back using a render library like OpenGL.
