A point cloud is a large set of 3D points, captured by laser scanning or photogrammetry, that records the exact shape of an existing building, site or object. Point clouds give accurate as-built geometry for renovation, retrofit and heritage projects.

## Why does a point cloud matter for architects, engineers and contractors in India?

Point clouds give accurate as-built geometry for renovation, retrofit and heritage projects. They can be used to create BIM models of existing buildings or to check construction against design.

## What is an example of a point cloud?

A laser scan of an old warehouse produces a point cloud that the team traces to create an accurate model before a conversion project.
