1.1 This specification describes a data file exchange format for three dimensional (3D) imaging data, known as the ASTM E57 3D file format, Version 1.0. The term E57 file will be used as shorthand for ASTM E57 3D file format hereafter. 1.2An E57 file is capable of storing 3D point data, such as that produced by a 3D imaging system, attributes associated with 3D point data, such as color or intensity, and 2D imagery, such as digital photographs obtained by a 3D imaging system. Furthermore, the standard defines an extension mechanism to address future aspects of 3D imaging. 1.3This specification describes all data that will be stored in the file. The file is a combination of binary and Extensible Markup Language (XML) formats and is fully documented in this specification. 1.4The values stated in SI units are to be regarded as the standard. No other units of measurement are included in this standard. 1.4.1Discussion Planar angles are specified in radians, which are considered a supplementary SI unit. 1.5This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. 1.6This standard does not purport to address legal concerns, if any, associated with its use. It is the responsibility of the user of this standard to comply with appropriate regulatory limitations prior to use.
