In this tutorial, you will learn how to use divider script, which separates existing reconstruction region in the open RealityCapture instance into rows and columns (matrix grid), and export those reconstruction regions (optional: with overlap).
Exported reconstructed regions are named based on their position in the grid. Please note that columns are defined on the Y axis, and they advance in the positive direction (+Y), and rows are defined on the X axis, and they advance in the positive direction (+X).
You will also be shown a script that can be used as an addition to the divider script. This script will import back every reconstruction region separately based on its name (rows and columns), and execute commands of your choosing, or wait for the interaction in the Command Prompt while you work manually in RealityCapture.
