![]() ![]() One of the greatest strengths of E57 is that it was designed to be readily extensible to accommodate new hardware innovations. Sections of the file and referenced from the XML section. The binary sections are notĮmbedded in the XML section. The bulk of the data, including point data and images, isĮncoded in the binary sections for efficiency. An E57įile is encoded as a hierarchical tree structure, some of which isĮncoded in XML, and some of which is encoded in a binary format that is To support efficient storage of large amounts of binary data. The E57 specification uses a subset of XML that has been extended The standard is available for purchase via the ASTM E2807 web site. Meanings of the data structures that compose an E57 file.Ī copy of the latest draft version of the specification can be obtained by joining the ASTM E57 committee of the ASTM. Reference to the standard, which documents the names, data types, and It would be difficult to effectively use the Foundation API without Reference that is needed to make full use of the library. Without reference to the standard, the standard is an essential While it is possible to utilize some aspects of the software The developers of the software were involved in the development of theĮ57 format standard, the software is not sanctioned or approved in anyĭo I need a copy of the ASTM E2807 standard? The libE57 software is not part of the ASTM standard, nor are theĪPIs defined within the libE57 software part of the standard. What is the relationship between the libE57 software and the ASTM E2807 standard? Matching your compiler/OS, it will be necessary to download the sourceĬode and compile it yourself. Pre-built binaries are provided for a selection ofĬompilers and operating systems (OSes). The source code for the libE57 software can be downloadedįrom this web site. (built on top of the Foundation API) that supports the most common use Relatively low-level, allowing control over all aspects of an E57 file, ![]() Theįoundation API is a full-featured interface that operates at a ![]() Separate application programming interfaces (APIs) for reading, writing,Īnd manipulating E57 files - the Foundation API and the Simple API. The libE57 software consists of a library, supporting utilitiesĪnd example programs, and documentation. Not intended to be the fastest possible implementation. ![]() It is not expected to be the only implementation, and it is The standard and to provide a reference to compare other implementationsĪgainst. It is intended to lower the barrier to adoption of The libE57 software is an open source implementation of the ASTM E2807 Standard Specification for 3D Imaging Data Exchange (known as the An overview of the design and implementation of the E57 format can be found in the paper " The ASTM E57 File Format for 3D Imaging Data Exchange." The libE57 Software Interoperability sub-committee of the ASTM E57 Committee on 3D Imaging Systems. The file format is specified by theĪSTM, an international standards organization, and it is documented in The E57 file format is a compact, vendor-neutral formatįor storing point clouds, images, and metadata produced by 3D imaging We would like to thank all the members of the ASTM E57.04 Data Interoperability Committee for a job well done. The final release of libE57 V1.1.312 is now available for download. LibE57: Software Tools for Managing E57 Files LibE57: Software Tools for Managing E57 files (ASTM E2807 standard) ![]()
