Is your feature request related to a problem? Please describe.

A bounding box similar to the feature in 3DF Zephyr allows you to define a volume(interactively in the viewport with a gizmo) to ignore data outside of it for future processing steps. This should allow for reducing computation and memory from observed data that the user knows is not important

Describe the solution you'd like

In other software, I have had a light point cloud generated with the alignment/extraction step. The bounding box can indicate the area of interest in case near/far points were added but not relevant for the final output(eg background/distance data of a scene, or the base of what the subject rests on top of).

This avoids generating dense points outside of the volume, or meshing outside of the volume, or any data that doesn't contribute much value to the the content within the bounding box volume for any other operations like texturing.

A similar tool can also delete points/triangles, useful for removing the base surface.

Describe alternatives you've considered

Current advice is to handle this via external tools like MeshLab.
