CySize operates as a virtual tape measure, allowing the user to extract point, length, area and volume measurements from a wide range of 3D mesh data, not just 3D scans of people.

The measurement points and curves are placed on the 3D mesh by the user. As an aid to locating points, color markers can be placed on the subject being scanned and these will seen by the user when the scan is loaded.

Because of its flexibility, CySize can be used to take any number of non-standard measurements of people in standard or unusual poses.
