This app can record a volumetric video.

When you turn on "NR", the noise such as point stream is removed.

When you turn on "MODE" (upper right corner of screen), you can use the accumulation mode.
It is a mode to capture multiple 3D images as a single frame and to make movie from these frames.
The default time interval is 1.0 sec.. It can be changed in the configuration.
**Unfortunately, this functionality is beta version.
The position matching between images is done using the IMU sensor only.
In the future, we plan to improve the matching accuracy.

The recorded video can be played by tapping the Files button to go to the file selection screen.
If you move the recorded file to the folder of the following App with the File App, you can also play it with this App.
