How to know if an .e57 file has normals

Introduction

Purpose

Determine if an .e57 file has Normals.

Procedure

Open the file in CloudCompare and click on one of the scans contained in the file.

• If the file has normals, you will see the entry ‘Normals’ in the properties table of the CC Object section and a check box to control visibility.

• If this option is not visible, it means the file does not have normals.

Alternatively:

1. Extract the XML portion of the .e57 file using the utility e57xmldump available here.

2. If the file has normals, you will see information about the normals for each scan position in the XML.
