gmio_logo ====================================================== [![Build Status](https://travis-ci.org/fougue/gmio.svg?branch=master)](https://travis-ci.org/fougue/gmio) [![Build status](https://ci.appveyor.com/api/projects/status/0q4f69lqo6sw9108?svg=true)](https://ci.appveyor.com/project/HuguesDelorme/gmio) Coverity Scan Build Status [![Coverage Status](https://coveralls.io/repos/fougue/gmio/badge.svg?branch=master&service=github)](https://coveralls.io/github/fougue/gmio?branch=master) [![License](https://img.shields.io/badge/license-CeCILL--B-blue.svg)](http://www.cecill.info/licences/Licence_CeCILL-B_V1-en.html) C library for geometry input/output =========================================== gmio is a reusable C library providing complete I/O support for various CAD file formats (eg. [STL](https://en.wikipedia.org/wiki/STL_%28file_format%29)) gmio aims to be [fast](https://github.com/fougue/gmio/wiki/4.-Benchmarks), portable (C90 conformance) and feature-rich. Main highlights: * [x] "Abstract" streams that does not tie the user to C stream(`FILE*`) * [x] Buffering of input/ouput for efficient device usage * [x] Operations can be easily aborted * [x] Progress report about the I/O operation * [x] Available under the CeCILL-B license, which is fully BSD compatible Supported CAD files format ========================== Current version only supports the STL file format (STereoLithography), but support is complete : * [x] ASCII format: Case-insensitive reading * [x] ASCII format: Output format(%f, %e, ...) and precision of floats support * [x] Binary format: Little/big endian support * [x] Binary format: 80-byte header and facet "attribute byte count" support * [x] Detection of the input format * [x] Retrieval of infomations about contents(facet count, solid name, ...) * [x] Multiple solids from stream(eg. 4 solids in STL ascii file) In addition, the STL module has the following advatanges: * [x] The user keeps its own geometry data structures, no mesh conversion needed * [x] Fixed memory consumption and independant of the mesh size * [x] Seamless use of OpenCascade [StlMesh_Mesh](http://dev.opencascade.org/doc/refman/html/class_stl_mesh___mesh.html) and [MeshVS_DataSource](http://dev.opencascade.org/doc/refman/html/class_mesh_v_s___data_source.html) in gmio Building gmio ============= gmio can be built with CMake, by default a static library is generated. Read the [Build instructions](https://github.com/fougue/gmio/wiki/2.-Build-instructions) Documentation ============= The HTML reference manual generated by Doxygen is [here](http://www.fougue.pro/docs/gmio) There is also a [wiki](https://github.com/fougue/gmio/wiki) How to report a bug =================== The gmio bug tracking system is open to the public at https://github.com/fougue/gmio/issues. If you think you have found a bug in gmio, we would like to hear about it so that we can fix it. Always include the following information in your bug report: * the name and version number of your compiler * the name and version number of your operating system * the version of gmio you are using * what configure options it was compiled with. If the problem you are reporting is only visible at run-time, try to create a small test program that shows the problem when run.
