I think it's because they already had proven capture hardware, harvest, and processing workflows.

But yes, you can easily use iPhones for this now.

Looks great by the way, i was wondering if there’s a file format for volumetric video captures

[darhodester]

Some companies have a proprietary file format for compressed 4D Gaussian splatting. For example: https://www.gracia.ai and https://www.4dv.ai.

Check this project, for example: https://zju3dv.github.io/freetimegs/

Unfortunately, these formats are currently closed behind cloud processing so adoption is a rather low.

Before Gaussian splatting, textured mesh caches would be used for volumetric video (e.g. Alembic geometry).

Edit: As I'm digging, this seems to be focused on stereoscopic video as opposed to actual point clouds. It appears applications like cinematic mode use a monocular depth map, and their lidar outputs raw point cloud data.

Recording pointclouds over time i guess i mean. I’m not going to pretend to understand video compression, but could it be possible to do the following movement aspect in 3d the same as 2d?
