E57 file extension - 3D Imaging Data Exchange format file

What is e57 file? How to open e57 files?

File type specification:

3d graphics, CAD-CAM-CAE file type icon 3d graphics, CAD-CAM-CAE file type

The E57 file extension is used for E57 3D Imaging Data Exchange format developed by the Data Interoperability sub-committee of the ASTM E57 Committee on 3D Imaging Systems.

The E57 File Format for 3D Imaging Data Exchange is capable of storing point cloud data from laser scanners and other 3D imaging systems, as well as associated 2D imagery and core meta-data.

An .e57 file is encoded as a hierarchical tree structure, some of which is encoded in XML, and some of which is encoded in a binary format that is not XML. The bulk of the data, including point data and images, is encoded in the binary sections for efficiency. Metadata, such as sensor pose information, is encoded in XML. The binary sections are not embedded in the XML section. Instead, they are located in separate sections of the file and referenced from the XML section.

The default software associated to e57 file type:

libE57  Microsoft Windows software

Company or developer:
ASTM Committee E57 on 3D Imaging Systems

The libE57 software is an open source implementation of the ASTM E2807 Standard Specification for 3D Imaging Data Exchange (known as the E57 format hereafter) in the C++ language

Help how to open E57 files:

E57 format can be opened with libE57 software.

How to convert file with extension E57:

As far as we know, this .e57 file type can't be converted to any other file format. This is usually the case of system, configuration, temporary, or data files containing data exclusive to only one software and used for its own purposes. Also some proprietary or closed file formats cannot be converted to more common file types in order to protect the intellectual property of the developer, which is for example the case of some DRM-protected multimedia files.
